How do bug foggers work?

Question

I'm doing a project for a marketing class I'm in. Does anyone know the technology behind those bug foggers you can buy? You know, like the Raid flea bombs? What exactly makes them work?

Answer 1

There are two common types of bug foggers. The simplest is the "bomb" type like Raid in a can. You depress the button and the aerosol floods the air with the insecticide. The vapor penetrate the living space - usually you have to leave drawers and doors open, depending on what pest you are targeting.

The other type are the propane type foggers. Thiss hand-held unit has a flame burner that heats a tube wrapped around it. As you pump the trigger insecticide (and typically kerosene) flow into the tube. The liquid is held back by a check valve. As it boils and vaporizes, it is forced out of the samll orifice in the front making a nice dense fog to flood your yard.
