Does fogging leave any unpleasant residual smell?

Does the fogger need to be preheated prior to using?

Yes, the foggers need to get to the proper working temperature, which takes only about 2 minutes. If not properly heated, the unit can squirt liquid onto your grass and plants.

How often do I need to pump the handle?

The optimal pumping interval is 3 to 4 seconds between pumps. If you pump too frequently, you may begin to squirt liquid as the insecticide is not given enough time to vaporize. Pumping too infrequently, can cause the fog to appear yellow or brownish in coloring, which means the insecticide is burning and the effectiveness can be diminished.

How long will fogging keep my yard mosquito free?

After fogging, you can expect your yard to be mosquito-free for up to 6 hours.

Does fogging repel or kill mosquitoes?

Fogging repels and kills mosquitoes. If you fog before dusk, the fog will reach the mosquitoes where they hide prior to emerging for their nightly feeding.

Is fogging more effective than those electric bug zappers?

Yes. Zappers do effectively kill mosquitoes as well as many "good" insects. But in order for them to work, they actually have to attract the mosquitoes, which may still bite you on their way to the light. Foggers kill mosquitoes where they hide before they even emerge for the night.
