7A General Pest Controls: Unit 7.
Application and Management Equipment
- Test Your Knowledge
True or False: You may safely place insect light traps (ILTs) near food preparation areas. - False. ILTs
may cause electrocuted flies to explode into prepared food.
What are bait applicators? For what type of application are they well suited? - 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.
How might you use a power sprayer? - To apply perimeter pesticide treatments around homes or
apartment complexes. Some product labels also permit treating the outside surface of homes and other
buildings to control insect pests. Other power sprayers are designed for use on wood floor joists and
mudsills in crawl spaces and basements as well as structural wood in attics, decks, and log homes
Describe the characteristics of ultra-low-volume (ULV) and ultra-low-dosage (ULD) applications. -
ULV and ULD systems create very small droplets and cover a relatively wide area (fogging). These
fine droplets can penetrate into narrow cracks and crevices. The droplets may remain suspended in the
air for several minutes before settling on horizontal and vertical surfaces, or directly on the target pest.
ULV and ULD systems can kill insects that remain "in the open" during an application as well as those
that hide in small harborages.
Describe some characteristics of dusters. - They leave pesticide dust on treated surfaces. Some
dusts remain active for long periods. You can direct the fine dust particles into areas where liquid sprays
cannot reach. The main types of dusters are hand dusters and power dusters. Dusters can effectively
treat infested harborages.
Describe the spray pattern delivered by a fan nozzle. - This nozzle puts out a band of spray. The
liquid in the band is distributed like a bell-shaped curve: most in the center, less toward the edges.
For what types of applications might you use a flat-fan nozzle? - For general or spot applications
on even surfaces.
, For what types of applications might you use a pin-stream nozzle? - Crack and crevice
applications. An injection tool (extension tube) directs and narrows the stream of pesticide.
How do you go about mixing a pesticide? - Read the label. Many products come ready-to-use, but
for those you have to mix yourself, the pesticide manufacturer provides dilution directions right on the
label. A spray dilution chart on the label lists the amount of product to be mixed with diluent (usually
water). The result is the recommended spray mixture..
How often should you clean a compressed-air sprayer? - If you use your sprayer daily, clean it
weekly. If you use it less often, clean it after each use.
Briefly describe aerosol systems and the proper use of aerosol containers. - Aerosols deliver small
droplets that remain in the air briefly. The droplets may also settle on a surface that pest will contact. As
a rule, use aerosol products as a directed spray, not as a space spray.
Briefly describe the special precautions for storage of aerosol containers. - Keep them in a cool
place. Overheating can cause the contents to expand, which can make the container explode.
Name and describe one popular type of compressed-air sprayer. - The 1-gallon stainless steel
sprayer. This sprayer with a multiple-spray nozzle can apply insecticides accurately into insect
harborages.
Name at least three kinds of traps used to monitor, catch, and/or kill pests. - 1. Snap (trigger)
traps.
2. Live traps.
3. Glue boards.
4. Insect light traps (ILTs).
Name some advantages and drawbacks of using ULD or ULV application equipment. - Low-volume
applications use a small volume of product. ULD and ULV systems produce very fine droplets, spread
efficiently over a large area. However, you must take special precautions when using these devices. First,
extinguish all pilot lights and other open flames in the application area because some products are
flammable. Second, wear a respirator. Manufacturers require respirator use to prevent inhalation
exposure.
