Advantages of thermal fogging
1. Smaller particles penetrate cracks and dense areas more thoroughly than
mist sprays.
2. Thermal fogging is recommended for treatment of large areas.
3. Thermal fogging is less likely to build-up an oily residue on plants,
furniture, etc. unless over applied.
Most insecticides are applied at a suggested rate of 1 ounce (30ml) per thousand
cubic feet of space. A 15-20 second application generally covers a 1,000 cubic
foot (28 cubic meters) area.
Note: to compute cubic feet multiply the L (length) x W (width) x H (height)
of area to be treated LxWxH= Cubic Footage.
Tips on thermal fogging outdoors
Thermal fog is affected by air currents and drafts which can carry the
product away from treatment area. For maximum effectiveness:
• Do not fog open areas outdoors on windy days.
• Outdoor fogging is most effective when performed at dawn or dusk.
• Move downwind and utilize the available outdoor air currents to circulate
and carry the fog over the target area whenever and
wherever possible.
Advantages of spraying
1. Preserves the potency of insecticides adversely effected by heating.
2. Applicator is better able to observe where solution is deposited.
3. Larger heavier spray droplets are not as easily affected by wind drift.

Special procedure for heavy insect infestations
One method of insecticide application which is very effective is to first apply a
suitable residual insecticide to cracks, crevices, and other probable partially
concealed or protected insect harborages. Then thermally fog the suspected
harborages and the airspace with a suitable
pyrethrum base insecticide which also acts as a
