Which application method delivers pesticide as fine droplets suspended in air, typically used for flying insect control?
Answer: Space spray or fogging
Space spraying or fogging disperses pesticide as fine airborne droplets to contact and kill flying insects in the treated area.
When applying a pesticide in a crack and crevice treatment, where should the nozzle be directed?
Answer: Into cracks, crevices, and voids where pests hide
Crack and crevice treatments target the harborage areas where pests live and breed, maximizing efficacy while minimizing human exposure.
What is the primary purpose of a pre-application site inspection before treating a structure?
Answer: To identify pest species, harborage areas, and conducive conditions
A thorough pre-application inspection identifies the pest, its harborage, and conditions that support it, enabling an effective and targeted treatment plan.
Which of the following best describes a 'spot treatment' application?
Answer: Applying pesticide only to specific small areas where pests are present or likely to occur
A spot treatment limits pesticide application to small, targeted areas, reducing overall pesticide use and non-target exposure.
What factor most directly affects the droplet size produced by a spray nozzle?
Answer: Nozzle type, orifice size, and spray pressure
Nozzle design, orifice size, and operating pressure together determine droplet spectrum, which affects coverage, drift, and efficacy.
When using a compressed air sprayer indoors, what is the maximum label-permitted application pressure for most indoor crack and crevice products?
Answer: 25 psi or as specified on the label
Labels for most indoor pesticides specify low pressures (often 25 psi or less) to minimize misting and aerosol drift that could expose occupants.
Which application technique is most appropriate for treating ant trails along a baseboard?
Answer: Directed residual spot or band treatment along the trail pathway
A directed residual treatment along ant trails places the pesticide exactly where ants will contact it, providing efficient control with minimal off-target exposure.
