7B WOOD DESTROYING PESTS UPDATED 2026 EXAM
QUESTIONS AND ANSWERS SCORED A+
✔✔Which would be a treatment for for drywood termites? - ✔✔Heat chamber for 4
hours at 140 degrees F and expose termite to 15 degrees F for 4 days
✔✔Wood Destroying insects: - ✔✔Powderpost Beetles: Consist of 3 families, larvae
(not adults) do most damage to wood
Longhorned beetles: usually .5 inches to 3 inches, damage usually limited to pine soft
wood, recognized by ripples on the surface of the galleries, larvae are called round
hound borers and feed on wood, doing most of the damage
Carpenter Ants: construct nests in wood but do not consumer it, live in colonies
Carpenter Bees: Excavate tunnels in softwood, black with yellow hair
E: occur only in wood having a moisture content greater than 20 percent
✔✔The most common structural pest in the longhorned better family is the; - ✔✔Old-
house borer
✔✔What is the best method for controlling wood decay fungi? - ✔✔Eliminate moisture
sources
✔✔Parts of Power Sprayer - ✔✔Tank: should be made of fiberglass or polyethylene to
be resistant to the corrosive properties of pesticides
Should have a guage to show the liquid and level
Pump: Used to generate hydraulic pressure to the pesticide directly in the line, rather
than pressurizing the tank
Hose: usually made of PVC and capable of with standing 600 PSI or more, usually has
an inside diameter of 3/8 inches of 1/2 inches
Applicator: various types, including rods and sub slab injectors
✔✔A typical tank on power sprayer used in termite control has a: - ✔✔100 gallon tank
✔✔what length is recommended for use in most termite control operations? - ✔✔150-
300 feet
✔✔Which is not true of backflow preventers? - ✔✔There is no chance backflow
occurring when using a backflow preventer, even when the outside pressure greatly
exceeds that of the water system
✔✔Which statement is true regarding protection of water supplies during a pesticide
application for control of subterranean termites - ✔✔High water tables can result in
contamination of pesticide contamination in water supplies
, ✔✔T or F: If the homeowner with a well tells you that he intends to hook up to a public
water supply, you should wait until he fills the caps and private well before apply
termiticide - ✔✔True
✔✔Where would be logical places to inspect for subterranean termites - ✔✔Places
where steps, porches, or concrete slabs join the structure. Basement and crawl space
walls. Sill plates, floor joints, and subfloors
✔✔Which is not true about proper structure and construction aspects of a building site?
- ✔✔The finished grade outside the building should slope toward the foundation
✔✔Which type of slab-on-ground construction is most susceptible to termite attack? -
✔✔Floating slab-on-ground (expansion crack all the way around it)
✔✔Which would be an effective barrier against subterranean termite infestations? -
✔✔stainless steel mesh termite shield
✔✔Which is true about sand barriers used in termite prevention? - ✔✔they are best
used when used in conjunction with other methods
✔✔Which is true about the use of treated lumber to prevent termite infestations? -
✔✔Chemically treated lumber should be sued for the foundation plate, mudsill, and all
lumber uses belowground
✔✔T of F: treating soil with insecticides to prevent termite infestations will substitute for
faulty construction methods - ✔✔F
✔✔Which is not true about use of biotermiticides in preventing termite infestations? -
✔✔Used alone, they have been shown to be more effective than soil termiticides
✔✔T or F: Borates injected into wood for the local control of termites have shown some
potential in preventing termite infestations - ✔✔T
✔✔Organophosphate insecticides are broken down in humans mainly by the: - ✔✔liver
✔✔An example of how an insect growth regulator functions in an insect is by -
✔✔interfering with molting
✔✔Which is true about fumigants? - ✔✔They are quick acting and usually eradicate the
pest
✔✔Which is not true about fumigants? - ✔✔Fumigants do not diffuse well through all
parts of the structure
