"What are the main purposes of sticky traps or pheromone traps? - CORRECT ANSWER=> To identify
the pest and help estimate the size of the pest population."
"True or False: You may safely place insect light traps (ILTs) near food preparation areas. - CORRECT
ANSWER=> False. ILTs may cause electrocuted flies to explode into prepared food."
"Describe the spray pattern delivered by a fan nozzle. - CORRECT ANSWER=> 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."
"What places on a power sprayer should you check regularly for wear? - CORRECT ANSWER=> Check
the hose and pump for wear and leaks to prevent accidental release. The nozzle is also a wear point.
Check its delivery pattern regularly."
"How might you use a power sprayer? - CORRECT ANSWER=> 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."
"Briefly describe the special precautions for storage of aerosol containers. - CORRECT ANSWER=> Keep
them in a cool place. Overheating can cause the contents to expand, which can make the container
explode."
"Briefly describe aerosol systems and the proper use of aerosol containers. - CORRECT ANSWER=>
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."
"Describe the characteristics of ultra-low-volume (ULV) and ultra-low-dosage (ULD) applications. -
CORRECT ANSWER=> 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."
"Name some advantages and drawbacks of using ULD or ULV application equipment. - CORRECT
ANSWER=> 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."
"What is the difference between cold foggers and thermal foggers? Which type is more often used? -
CORRECT ANSWER=> Cold fog generators break insecticide into aerosol droplets mechanically. Cold
foggers are mounted on trucks and are used to control mosquitoes, pests in large warehouses, and flies
in some operations. Thermal fog generators break liquid pesticide into droplets using heat. Thermal
foggers produce a mixture of pesticide and fuel oil. They work by vaporizing the mixture or solution to
produce fine droplets. Cold foggers are more common."
"Describe some characteristics of dusters. - CORRECT ANSWER=> 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."
"Name three types of hand dusters. Which type is especially effective in crack and crevice application? -
CORRECT ANSWER=> Bulb dusters, bellow dusters, and plunger dusters. Bellow dusters have a spout
with a tapered tip. These dusters effectively propel pesticide dust into cracks and crevices."
"What safety precautions must you take when using power dusters? - CORRECT ANSWER=> Confine
the dust so that it does not drift into non-target spaces. Turn off pilot lights and flame or spark producing
equipment if you are using a combustible dust (one that is likely to catch fire). Protect smoke alarms."
"Why is it important to calibrate your spray equipment? - CORRECT ANSWER=> Calibration allows you
to dispense just the right amount of chemical. If you use too little, you may not achieve good control. If
you use too much, you may waste money, contaminate the spray area, and face penalties for exceeding
the label rates. Calibration techniques help you to configure the output of your sprayer so that you know
exactly how much you are applying to a given area."
"True or False: Changing nozzle pressure is a good way to make moderate to large changes in sprayer
output. - CORRECT ANSWER=> False. Changes in pressure should only be used to make minor changes
in output. This is because a drastic change in pressure will also change the nozzle pattern and droplet
size."
