Test Your Knowledge
Name and describe one popular type of compressed-air sprayer. - answer✔✔The 1-gallon
stainless steel sprayer. This sprayer with a multiple-spray nozzle can apply insecticides
accurately into insect harborages.
Name three commonly used sprayers in general pest control. - answer✔✔Compressed-air
sprayers, backpack sprayers, and power sprayers.
What parts of a compressed-air sprayer should you inspect regularly? - answer✔✔Check the
spray tank inside and out. Look for pinholes and stripped threads. Examine the check valve and
plunger cup of the pump unit for wear and damage. Inspect the hose for cracks and soft spots.
Check the nozzle by using a spray pattern check tray.
For what types of applications might you use a pin-stream nozzle? - answer✔✔Crack and
crevice applications. An injection tool (extension tube) directs and narrows the stream of
pesticide.
For what types of applications might you use a flat-fan nozzle? - answer✔✔For general or spot
applications on even surfaces.
How often should you clean a compressed-air sprayer? - answer✔✔If you use your sprayer
daily, clean it weekly. If you use it less often, clean it after each use.
To mix insecticide concentrates, what temperature water should you put in the spray tank? Why?
- answer✔✔Cool. Warm water helps break down pesticides and increases their odor. Never use
warm water to mix pesticide sprays.
True or False: Backpack sprayers are a good choice to apply pesticides in homes and small
businesses. - answer✔✔False. Backpack sprayers are designed for continuous spraying of large
areas such as commercial food facilities and warehouses.
What are some advantages of using bait stations? - answer✔✔These devices are small and easy
to move and place. They are designed to attract the target pest, not nontarget organisms. The
toxin is contained, so that it is not easily accessible to children and pets.
Name some factors that determine success in baiting for pests. - answer✔✔1. Know when,
where, and how to place baits and bait stations.
2. Choose the baits that you know pests like to eat.
3. If using guns or other injection devices, keep the delivery tube capped when not in use so the
bait does not dry out.
4. Do not contaminate baits with spray insecticides that might make the bait less attractive to
pests.
Name at least three kinds of traps used to monitor, catch, and/or kill pests. - answer✔✔1. Snap
(trigger) traps.
2. Live traps.
3. Glue boards.
4. Insect light traps (ILTs).
What type of pest would you be most likely to catch with a trigger trap? Where should you place
the traps? - answer✔✔Rodents (mice and rats). Place traps close to the walls, behind objects in
dark corners, and in other areas where rats and mice are active. Place traps so that rats and mice
will pass directly over the trigger as they follow their natural course of travel (usually close to a
wall).
Why is it important to match the size of a trigger trap with the size of the target rodent species? -
answer✔✔Using a mouse-sized snap trap to catch rats is inappropriate and ineffective.
Conversely, using a rat trap to catch mice will lead to many sprung traps with few captures.
What is the main advantage of using glue boards to catch rodents? The main drawback? -
answer✔✔The main advantage of using a glue board is that you can release non target catches
relatively unharmed by applying a coating of vegetable or cooking oil. However, glue boards do
not kill quickly. Captured animals may suffer a slow and inhumane death if they are left
unattended for a long time or if they are discarded, still living, along with the glue board.
What are bait applicators? For what type of application are they well suited? - answer✔✔Bait
applicators, or "guns," have dispensing tips that allow you to apply insecticidal pastes and gel
baits packaged in various ways. They are well suited to treat cracks and crevices.
What are the main purposes of sticky traps or pheromone traps? - answer✔✔To identify the pest
and help estimate the size of the pest population.
