In-Depth Information
cooler air, it condenses into very fine droplets, producing a fog. Figure 8.18
shows a vehicle-mounted fogger.
Other aerosol generators (cold foggers) break the pesticide into aerosols by
using mechanical methods such as:
rapidly spinning discs
extremely fine nozzles and high pressure (atomizing nozzles)
strong blasts of air.
This specialized equipment is most often used in greenhouses, barns,
warehouses, and other structures and for biting fly and mosquito control in
outdoor recreation areas.
Advantages:
no unsightly residue
safe reentry immediately after ventilating the area
penetration in dense foliage
penetration of cracks and crevices and furniture
some indoor devices are automatic and do not require presence of
applicator.
Limitations:
aerosols and fogs drift easily from target area —use outdoors is
limited
no residual control—pests may return to the area as soon as fog
dissipates
risk of explosion in enclosed areas.

SELECTION, USE, AND CARE
Choose an aerosol generator according to where you will use it—indoors
or outdoors. Aerosol and fog generators are manufactured for many special
uses. There are truck- and trailer-mounted machines for use outdoors. Most
hand-operated or permanently mounted automatic machines are for use indoors.
In general, use and care for an aerosol generator as you would a sprayer.
They do require special precautions. Be sure that the pesticides used in them
are registered for such use. Keep them on the target. Because of the effects of
weather conditions during application, follow special use instructions. The
operator, other humans, and animals must be kept out of the fog or smoke
cloud.
