Prevention
following the Supreme Court Ruling is
the key to proper, effective, least hazardous, and legal urban pest management
programs in all government buildings and structures.
Briefly,
the SC decision that upheld all lower court rulings, the MMC Pest Control Board, and the Department of Health Circular 155 ruled that it is the National Committee on Urban Pest Control [NCUPC] that has jurisdiction
over urban pest control. As cited by the ruling, “the NCUPC was created pursuant to the Memorandum of Agreement signed
by the Office of the President, the Metro Manila Commission, the Department of
Labor & Employment and other government agencies and non-governmental organizations
per Presidential Decree 856 [Sanitation Code], 522 [Sanitation requirements for
establishments catering to traveling public], and 1096 [Building Code], PD
1423, and President Corazon Aquino’s Executive Order 432, RA 3850, PD 1423 as
amended by EO 128. Through the NCR Pest Control Board and the MMDA Pest Control
Board, the practice of pest control is governed.” The NCUPC, by virtue of Presidential
Proclamation 990, can harmonize laws
and various government offices related to pest control.
If
the conditions that attract and support pests, that is, the presence of food or
organic debris, water, shelter, and access are improperly eliminated, then
other management practices are most likely to fail. The building management
including all occupants must be involved in the planning, design, construction,
remodeling or retrofitting of the government building and structures should be
aware of the need for long-term prevention or suppression of pest problems. Pest
prevention will reduce overall costs of pest control operations as well as
other maintenance and operating expenses.
A
thoroughly and legally integrated approach to urban pest management in government
buildings and structures begins in the early planning stage. Too often, pest
management or pest proofing is not considered, is neglected, or is just taken
for granted at this point. The way a government building or structure is put up
including materials, construction techniques, and attention to detail will
impact any future pest management efforts throughout the life of government building
or structure. So there’s a need to consider pest management needs during
design, development and construction of government building and structure where
the National Committee on Urban Pest
Control Licensed Pest Control Provider follows the phases of building and
structural construction means to incorporating features that will exclude
pests, minimize pest habitat, and promote proper sanitation.
Several
basic building and structural features can cause most of the pest problems.
Many government buildings and structures have pest exclusion problems at
doorways and windows. Heating, air conditioning, plumbing, electrical service,
and fire sprinklers provide other pest entry points. Even in newly constructed government
buildings and structures, electrical conduit, water and gas lines, and
communication cables generally have large openings that permit pest entry. Wall
cavities, ceiling cavities, and the space beneath floors can all provide pest
shelter. From these areas, pests generally have ready access to the rest of the
building and structure. Utilities, overhead suspended ceilings, and air
conditioning ducts provide a very effective pest distribution system. So
there’s a need for all existing government buildings and structures to be
regularly inspected by the NCUPC to
assess them in terms of pest infestation and the soundness of the structures
against termite and other pest damages. The NCUPC then prepares the technical
program to form the basis for
bidding pest control services per RA
9184 [Government Procurement Reform
Act].
Although
pest-resistant building and structure practices most commonly reduce shelter
and access, they can also reduce food and moisture sources through proper
sanitation, reducing trapped moisture, and improving drainage.
While
proper construction practices are the emphasis here, they cannot stand alone. A
strong and legal urban pest management and maintenance program is essential.
Poor sanitation or leaving entryways open will make even the best designed and
constructed building susceptible to pest problems. Using the practices
discussed below, together with regular
routinary inspection conducted by National
Committee on Urban Pest Control Licensed Pest Control Provider, and
awareness of potential pest problems among staff management of government
building and structure and occupants by the NCUPC information dissemination education, can greatly reduce or
eliminate the potential for infestations, especially when followed by
responsible maintenance.
The
following guidelines and best practices illustrate the variety of practices
that can be used and their value in pest prevention in government structures
and buildings. No single practice will work equally well in all circumstances.
Certain practices listed below may not be appropriate where structural
requirements or budget considerations preclude them. Once the basic principles
are understood, there is no substitute for resourcefulness and ingenuity in
developing practical, site-specific solutions.
1. PRE-CONSTRUCTION
GUIDELINES AND BEST PRACTICES
A. FOUNDATION AND
SLABS
- Eliminate gaps or flaws in
foundations and slabs, or where the wall framing meets the foundation or
slab floor. These openings may be large enough to allow entry for insects
and rodents. Older buildings commonly have cracked foundations, cracked
plaster or mortar, warped siding, or broken and torn vent screens that
allow pest entry.
- Install physical barriers
beneath joints or other discontinuities in the foundation. No hidden cold
joint should exist in the foundation unless there is an installed physical
barrier. A sheet of metal barrier to termites can be installed from below
the wall sill plate or first block course horizontally to embed in a
mortar joint.
- Include the design of footings
for brick, stone, or other veneers with the other pre-construction
foundation planning. A concrete bearing ledge that is poured integrally
with the concrete foundation should support these heavy veneers. If poured
as part of the foundation, the ledge prevents termite entry into the
building between the footing and the foundation.
- Use a sand barrier. Use a
3-inch layer of sand underneath slab construction. Use 1-3 millimeter
particle size in place of unsifted sand to provide a permanent termite
barrier for subterranean termites. This will prevent termites from
penetrating the cracks in the slab construction.
- Use natural durable wood, kiln
or chemical-treated wood or non-wood materials. The only sure prevention
of termite problems is the use of building materials other than wood.
- Eliminate all wood-to-soil
contact as much as possible. Soil should always be from 6 to 18 inches
below any wood member, the greater the distance, the better.
- Extend foundation below ground.
Good foundations will normally stop rodents from getting into buildings;
however, if foundations do not rest on bedrock, they should extend
vertically below ground at least 3 feet or have an L-shaped curtain wall
about 2 feet deep with a 1-foot projection from the building. On piled
foundations, the reinforced concrete beam spanning the piles should extend
3 feet below ground to stop rodents.
- Modify foundations on older
buildings with concrete or metal barriers to stop rodents from digging
their way in.
- Check foundation vents to make
sure they are tight and appropriately screened (use a hardware cloth to
exclude rodents).
- Avoid burying or storing
cellulose-containing material (such as wood scraps, form boards,
vegetation, stumps, large dead roots, cardboard, trash, and foreign
material) near or under the structure. To reduce chances of termite
infestation, no cellulose-containing material should be buried on the
building lot within fifteen feet of any building or the position of any
building proposed to be built. Cellulose materials are attractive food
sources for subterranean termites that can then move into the structure.
- Prior to concrete placement,
remove all cellulose-containing material such as form boards from the area
encompassed by the foundation and the area within one foot of its
perimeter. The fill material should be free of vegetation and foreign
material.
- Prior to concrete placement,
clean all cellulose-containing material from cells and cavities in masonry
units, and from air gaps between brick, stone, or masonry veneers and the
structure.
- After all foundation work is
completed, remove all loose wood and debris from the crawl space and
within one foot of the perimeter of the building. All wood forms and
supports should be completely removed.
- Eliminate sources of chronic
moisture in and around the structure. This is one of the most important
requirements for successfully managing subterranean termites, carpenter
ants, and wood boring beetles. Good drainage design will help to prevent
moisture build-up in and around the building or structure.
- Use moisture barriers. In
above-ground foundations, moisture barrier films such as 6 mil
polyethylene can be used to cover the area under the structure. This will
help decrease moisture buildup in sub-flooring. Some builders recommend
the use of moisture barriers under slab foundations as well.
- Slope all exterior grades away
from the structure to provide drainage.
- Construct and seal all
adjoining components such as porches and planter boxes to prevent moisture
and soil contact with the structure.
- Design exterior landscaping so
it does not cause moisture build-up around the foundation. Maintain
clearance between vegetation and exterior walls.
- Align and/ or shield sprinkler
irrigation heads to direct spray away from the building.
- Place foundation wall vents to
provide cross ventilation for buildings with crawl spaces. If regrading or
remodeling covers vents, additional vents may be needed.
Facilitate
inspection and maintenance
- Provide adequate clearance to
allow access for inspection and control if needed. Construct decks,
fences, patios, planters, or other wooden structural components that
directly abut the sidewall of the foundation or structure to provide: (a)
an 18-inch clearance beneath or, (b) provide for 6-inch clearance between
the top of the component and the exterior wall covering or, (c) have
components that are easily removable by screws or hinges to allow access
for inspection of the foundation sidewall and treatment for termites.
- Eliminate gaps around floor
joists. Floor joists should be built in or fitted onto joist hangers.
Facilitate
sanitations/ harborage reduction
- Build floors to be durable,
non-absorbent, anti-slip, without crevices, and capable of being
effectively cleaned. If concrete is used, it must be steel-float finished
and sealed. Slope floors sufficiently for liquids to drain to trapped
gullies or drainpipes. The floor area under food preparation equipment
should allow easy cleaning of food spills and remain open to prevent
harborage.
- In areas where hazard from
termite damage is most critical, use floor framing of natural and durable
wood and follow the proper methods of termite protection for foundations.
- Provide adequate ventilation.
Allow at least 18 inches of clearance under floor framing and at least 12
inches under floor girders. Proper ventilation and use of vapor barriers
on the ground in the crawl space will help prevent the moist conditions
that subterranean and dampwood termites favor. The minimum ventilation
requirements in building or
structure must be based on the ratio of the net free vent area (a
measurement of a vent’s unrestricted opening) to the area of crawl space
to be ventilated.
C. INSIDE WALLS,
CABINETS, SHELVING, STORAGE ROOMS
Exclusion
- Install wall cavity closures
and avoid joist/ rafter gaps. Cavity closers should be installed at the
top of all cavity walls and there should be no gaps between joists and
rafters. This will keep out various pests that have gained access to the
attic such as birds, mice rats and squirrels.
- Eliminate gaps around wall
penetrations. Wherever drains, hoists, and vents, conveyors, pipes, cable
conduits or ducts pass between buildings through walls or foundations,
they should be sealed to prevent the spread of any infestation from one
building to another.
- Equip storage areas with
self-closing doors to deny pest access.
- Eliminate cracks and crevices,
that is, with sealant, or copper or bronze wool wherever possible,
especially in kitchens and other food preparation and storage areas.
- Eliminate dead spaces inside
storage areas to restrict areas where rodents may hide. Dead spaces
include double walls, false ceilings, enclosed staircases, boxed plumbing,
and voids or false bottoms under cabinets.
- Do not use wall coverings that
provide insect harborage. Do not install pegboard in kitchens, or other
food service areas, animal rooms, or laboratories.
- Construct walls for easy
cleaning. Wall surfaces are best when smooth, impervious, non-flaking and
light-colored, and must be capable of being thoroughly cleaned. Do not use
absorbent emulsion paints. Stainless steel splash-backs are recommended
behind sinks and working surfaces. Coving should be used at wall to floor
and wall to ceiling junctions to help cleaning operations and minimize
debris accumulating. Avoid construction of wall-to-wall junctures less
than 90 degrees. Slope floors in kitchen areas to provide good drainage
after cleaning.
- Use durable, non-absorptive
shelving material. Keep shelving far enough away from walls to leave room
for cleaning.
- Areas where susceptible items
are stored should be well lighted for ease in cleaning and inspection.
Moisture
management
- Ventilate cavity walls.
Adequate ventilation must be provided but any openings into the roof for
this purpose must be screened with mesh or hardware cloth.
- Eliminate gaps around joists.
On multi-story buildings or structures, floor joists should be built in or
fitted onto joist hangers.
- Seal all internal partitioning
wall and ceiling cavities.
- Build for ease of maintenance.
Suspended ceilings should be made of metal lattice incorporating cleanable
panels. Aluminum backed and faced fiberboard has proved successful in many
food factories. Flush-fitting ventilation grilles should be installed
tightly enough to eliminate openings around the edge of the grille. Solid
ceilings should be well insulated to avoid condensation and mold growth,
and should be smooth, fire-resistant, light colored, coved at wall joints,
and easy to clean.
Facilitate
inspection and maintenance
- Build in inspection and maintenance access. Suspended
ceilings are helpful in hiding horizontal pipe work and services but
access for inspection for pests and maintenance must be built in.
Structural walkways should always be provided in large premises.
- Seal utility entry points on
the building exterior. Junctures where utilities such as pipes and cables
enter structures require special consideration to prevent pest entry.
Pests, especially rodents, often find easy access into buildings through
holes beside water pipes and electrical conduit, and through the cold air
return ducts on forced air furnaces. Utility entry points include exhaust
vents and underground electrical lines. Power lines have always been a
favorite route of travel for rodents, especially rats. Old, unused
openings where utilities formerly entered the structure should also be
inspected for cracks, broken screens, damaged doors, and uneven floors
near doorways. Any external meter boxes must have close-fitting doors; all
connected pipes or wires must be adequately sealed.
- Seal entry points within the
structure. Once inside the wall, pests may gain entry into the main
structure along electrical lines, pipes, poorly sealed fire wall
sheathing, or around furnace ducts, hot water heaters, or laundry drains.
If pests are able to reach the attic, they may travel from room to room or
unit to unit through openings for pipes, ducts, and wiring.
[Pipes, ducts or cables passing through walls should fit
tightly or be built into fire stops. Protect joists with metal flanges where
pipes or ducts pass through floors and walls. Hot water pipes should be carried
in sleeves through vertical or horizontal partitions. Surround the base of
elevators, conveyors and machinery with a 2-foot high smooth metal fence;
conveyor ends should have tight-fitting doors. Seal around all electrical
conduits, plumbing, heating pipes, trunking or service ducts that pass through
them.]
- Seal duct work. Ensure that all
heating and air conditioning ducts are tightly sealed at seams and joints.
- Ensure that all pipe insulation
has a smooth surface and that there are no gaps between pieces.
Facilitate inspection and maintenance
- When installing pipes, cables
and fittings, build in or allow enough wall clearance to enable cleaning
around the entry point. Flexible fittings are recommended for gas
fittings. All electrical switches should be flush-fitted.
- Ensure that doors are properly
installed and correct problems that interfere with a close fit. Pest entry
problems can arise when doors are hung unevenly or too high, or lined with
unprotected soft rubber weather stripping. Insects and rodents, especially
mice, often find easy access to buildings through open doors or under and
beside poor-fitting doors, particularly in receiving areas and garage
areas.
- Ensure that roll-up or overhead
doors are well fitted. With the door closed, check for gaps along the
sides, bottom, and top of the door. A gap at the top is common. Roll-up or
overhead doors often provide easy entry for rodents, birds, and bats. Rats
and mice can easily climb up the space between the door and the inner wall
or track to the top, where they gain entry and climb down the inside of
the track. Gaps between the track and the wall are also common, especially
if the track has been installed on brick walls. Door bottoms may be bent
or damaged, leaving gaps along the floor. Uneven floors due to frost
heaves may leave gaps when the door is closed.
- Use self-closing doors. All
doors should close on a level threshold, have smooth, non-absorbent
surfaces, be tight fitted and self-closing. Doors of bin rooms below
refuse chutes should be self-closing, flush-fitted and of metal
construction.
- Select door styles for ease of
maintenance and durability. Use polypropylene or toughened rubber doors
for ease of maintenance.
- Correct mail slot/ letter
plates that are not at least 30 inches above ground level to prevent them
becoming 'rat flaps.'
- Avoid the use of door frames
with acute angles.
- Use woodwork that is
well-seasoned, properly-knotted, stopped, primed, and given three coats of
polyurethane paint.
- Modify conventional doors. External
doors should be fitted with metal kick-plates not less than 1 foot high
and the metal plates should also fit jambs and door linings.
- Use nylon bristle door sweeps;
these are remarkably versatile for pest-resisting conventional doors.
- Install close-fitting windows
and screens. Poorly fitted windows or screens allow easy rodent entry from
exterior utility lines and pipes running along exterior walls. Runways
going to window ledges are often observed on stucco and brick walls and in
ornamental plantings next to buildings. Screens on windows, crawl spaces,
and vents are often damaged in government buildings and structures. Check
these carefully for needed repair or replacement.
- Slope window ledges. Window
ledges or other essential projections should slope at 45 degrees to
discourage birds from perching and roosting on them.
- Modify windows to prevent
harborage and access for pests, with no clear passageways to inside.
Modify weep holes, that is, openings that allow drainage of moisture in
window frames, that is, with copper or bronze wool to prevent access by
paper wasps and other insects.
H. OUTSIDE WALLS AND
BUILDING PERIMETERS
- Do not install exterior features that attract insects,
rodents, birds or other wildlife. Avoid installation, particularly near
entrances, of the following:
o Light fixture designs that may provide opportunities for
bird perching, roosting or nesting;
o Decorative lattices or other structural features that may
inadvertently serve as bird roosts, over entrances to food services facilities;
and
o Structural features that provide opportunities for rodent
harborage or burrowing. Install bird-proof barriers (e.g., netting) that are
designed to prevent both pigeon and sparrow access to preferred nesting sites.
- Use enclosed fire escapes to
eliminate bird perching, roosting and nesting, and access for other pests.
- Use durable pest-proof
construction materials. Buildings and structures are constructed from
types of materials and design methods that vary greatly in the degree of
susceptibility to pest infestation, for example, metal and concrete versus
wood. Most structures eventually become less pest-proof due to
deterioration, alteration, or lack of repair. Pre-fabricated building
panels usually provide more opportunity for infestation to develop than do
solid brick or concrete walls; certain partition or cladding materials
such as chipboard, hardboard or block board offer little resistance to
gnawing of rodents and may, especially if damp, encourage molds, booklice
and fungus beetles.
- Avoid rough finishes that can
be gnawed or provide foothold. Rats and mice will climb up rough exterior
surfaces so it is best to eliminate such finishes and to avoid projections
or ledges which might give a foothold or provide access to any higher
points of entry that are unlikely to be as well proofed as those on the
ground floor.
- Screen or otherwise eliminate
animal access under decks, porches, and stairways. Seal porches and ramps
to the building foundation with hardware cloth screen mesh to form a
barrier to digging pests such as rats and skunks. This screen must extend
12 inches into the ground and must have a right-angled, 6-inch wide,
outward extending shelf to prevent burrowing under the screen.
- Use gravel to discourage
burrowing. Where feasible and inaccessible to people, maintain a 2-foot
pea gravel strip around buildings to prevent rodent burrowing.
- Install guards on pipes and
downspouts. Standard conical or rectangular metal rat guards should be
fitted to soil pipes and rainwater downspouts, projecting about 9 inches
from the pipes and built into the walls at the point where they touch it.
Fit tops of open pipes with balloon guards. Mesh fitted over rainwater
downspouts will keep out nest debris.
- Design exteriors that have no
access to wall cavities. To protect against mice, no external or other
cavity wall should have any holes larger than ½ inch in diameter. Modify
weep holes, that is, with screening in walls to prevent access by insect
pests.
- Install fitted grills over air
intakes.
- Consider pest management when landscaping near buildings
and structures.
I. EXTERIOR SIDING
- Avoid gaps at edges and
corners. Wood or masonite siding is especially vulnerable to warping and
cracking near corners and around the base of the building and structure.
Buildings constructed with ribbed or corrugated metal siding allow rodent
entry if the bottoms of the siding panels do not rest flat on a solid
surface or they are not otherwise closed off. Sections of pre-fabricated
buildings or structures should be assembled tightly, and gaps at joints
should be covered with metal flashing; joint gaps are often left open,
especially at corners and at the foundation/ slab interface.
Facilitate
inspection and maintenance
- Allow clearance for inspection
between siding and soil surface in order to provide access to inspect for
termite infestation, and to prohibit exterior siding contact with soil,
clearance between exterior wall coverings, that is, stucco, siding, and
soil on the exterior of a building should not be less than 6 inches.
- Irrigation/ sprinkler systems
and risers for spray heads should have sprinkler heads or be located two
feet from the building and structure so as to prevent water contacting
walls; including drought tolerant plants in landscape plans can aid in
achieving this goal.
- Eliminate rodent access under
shingles. Shake shingle roofs allow rodent entry if the roof is not
solidly sheeted with plywood or similar material and the shingles are not
properly fitted. Use vents with tightly fitted double roof jacks and/or
heavy-duty screen to prevent small animal access.
- Build tight roof joints and
protect with flashing. Ensure tightness of all roof joints and the
presence of flashing if rats and mice have access to the roof via wire,
pipes, plants, or rough-textured walls. Ensure proper installation of
metal flashing on roof, wall joints and edges.
- Fit eave roof tiles with bird
stops. This will also exclude bats, bees and wasps.
- Make sure all attic and soffit
vents are properly screened to exclude insects, birds, and other animals.
Use hardware cloth screen mesh.
- Direct water from drainage and
sprinklers away from walls. All condensate lines, and roof down spouts
should discharge at least one foot away from the structure sidewall,
whether by underground piping, tail extensions, or splash blocks. Use
gutters with down spouts on all buildings with eaves of less than six
inches horizontal projection except for gable end rakes or on a roof above
another roof.
K. REFUSE AND
RECYCLING AREAS
- Locate site away from building and
structure entrances or at least 50 feet from doorways.
- Design site with properly
graded concrete or asphalt pads to help prevent rats from establishing
burrows beneath them.
- Build to exclude vertebrates.
Build refuse sites with a solid enclosure that extends all the way to the
ground. Use metal or synthetic materials, as opposed to chain-link or
wood, to prevent rodents and other wildlife from gnawing or climbing the
enclosure.
- Close off refuse, recycling,
and trash storage areas. If trash will be stored, design storage areas
that can be closed off from the rest of the building. Locate storage areas
for boxes, paper supplies, and other materials in areas separate from
where food or trash is stored. When stored together, these materials put
food and shelter together, favoring pests.
- Place outdoor garbage
containers, dumpsters, and compactors on hard, cleanable surfaces.
- Include a water source at the
site for cleaning permanent storage containers and pad surfaces; ensure
adequate drainage.
- Floor cavities should be sealed
where they enter shafts or chutes.
Facilitate
sanitation/ harborage reduction
- Shafts or chutes should be of
smooth internal construction. To the extent feasible, build or modify
these areas, that is, use coving at floor to wall junctures, or other
means of minimizing corners and sharp angles to reduce debris accumulation
and to facilitate cleaning.

3. EXISTING
GOVERNMENT BUILDING AND STRUCTURES TERMITE AND PEST PREVENTION AND CONTROL GUIDELINES
AND BEST PRACTICES
For effective prevention and/ or control of
termites in government buildings and structures, the National Committee on Urban Pest Control Licensed Pest Control Provider
hereby recommend the following technical services following a process of
treatment procedure described as follows:
TECHNICAL SERVICES:
A. SOIL TREATMENT (ST)
·
ST prevents subterranean termites from
damaging the wood component of the building and structure by properly treating
the soil around it using appropriate equipment by either cordoning, trenching
or injection method. The distance shall
be about l8-20 inches apart and about six inches close to the external wall of
the building and structure.
·
ST uses only
approved
NCUPC Registered Environment-friendly termiticides
with no health
risks and proven effective
against the target pests. This creates soil that is an
uninhabitable environment for subterranean termites.
·
This
is accomplished by using a power machine operated and run by a five-horse power
(5HP) machine at a pressure of 150 Psi and at an approximate rate of 2 gals.
solution per 45 seconds. Dilution rate
of the termite should be strictly followed and complied with by the National Committee on Urban Pest Control
Licensed Pest Control Provider.
·
Treatment Frequency: One General Treatment (GT) Only.
B. DRILLING SERVICE
·
Drilling
service is done in order to treat the soil under cemented floorslabs using heavy-duty HILTI FE24 Rotary Hammer
Drill (220V/ 740W) with the speed under load of 275-570 rpm and hammering power
of 3,100 blows/ minute and drilling performance in medium-grade concentrate of
40 cubic meter per minute = 260 mm/ min. Recommended diameter range is 12-20 mm
diameter, using heavy-duty Black & Decker bit of 48 cm long in diameter.
·
Before
any drilling service is conducted in building and structure, the building
management should provide the National
Committee on Urban Pest Control Licensed Pest Control Provider with a floor
plan indicating underground water, electrical and puso negro pipes.
·
Perimeter
drilling distance is one (1) meter apart and six (6) inches close to the wall.
·
With
this service, we can inject only approved NCUPC Registered Environment-friendly termiticides solution with
no health risks and proven effective against the target pests through soil
injector using the power machine deep under the surface to penetrate the hidden
areas so susceptible to subterranean termites with a rate of two (2) gal.
solution per hole. This gives greater structural protection.
·
Treatment Frequency: One (1) Treatment Only.
C. WOOD DRENCHING (WD)
·
WD
is designed to treat all infested parts of the building and structure,
concentrating on the floors, walls, baseboards, cracks and crevices by direct
spraying of only approved NCUPC
Registered Environment-friendly termiticides with no health risks and proven effective against the target pests at a correct
dilution rate.
·
This
treatment is to control the surface infestation on the spot and help minimize
further infestation in the building and structure.
·
Treatment
Frequency: One General Treatment (GT)
Only.
D. TERMITE ABATEMENT MAINTENANCE PROGRAM (TAMP)
·
TAMP
service is properly accomplished and done by dusting or trophallaxis method. Treatment
of the infestation by injecting only approved NCUPC Registered Environment-friendly termiticide powder with no
health risks and proven effective against the target pests at a correct
dilution rate in the doorjambs, electrical outlets, panel boards, double
walling, and cabinet. Either a rubber
or plastic applicator may be used in order to treat the infested areas and
other possible susceptible areas for termite.
·
If
the building and structure is already termite infested, there’s nothing like a
regular termite check-up. During the General Treatment (GT) and Quarterly Treatments
(QT). Only National Committee on Urban
Pest Control Certified Applicator shall conduct the inspection and
treatment to minimize the possibility of an infestation by drywood termites,
dampwood termites as well as subterranean termites.
·
Frequency: One General Treatment (GT) Only, and
Quarterly Treatment (QT) per quarter for a
period of One Year.
E. BUKBOK
ABATEMENT MAINTENANCE PROGRAM (BAMP)
·
Wood-boring
beetle or “bukbok” make pinholes on the walls causing sawdust on your floors
and eventually damage the building and structure. Although not as numerous as
the termites, this pest is much harder to control.
·
Depending
on the severity of infestation, BAMP may be done in the following manner: Spray or brush the infested area thoroughly,
inject every pinhole with a termiticide concentrate or conduct fumigation to
wipe out the infestation.
·
Treatment
Frequency: One General Treatment (GT)
Only.
F. MOUND
DEMOLITION (MD)
·
Termite
mounds are the homes of subterranean termites. These colonies are where the
queen lays eggs and the king, secondary reproductive, soldiers and workers
live. Termites attack and penetrate the
building and structure even if these mounds are 200-500 feet away from the building
and structure.
·
Only
National Committee on Urban Pest Control
Certified Applicator shall search for these termite mounds in the
surroundings, demolish them, retrieve the queen, and thoroughly treat the
surroundings using only approved NCUPC
Registered Environment-friendly termiticide with no health risks and proven effective against the target pests.
·
Treatment
Frequency: One General Treatment Only.
