Safety Precautions for Total Release Foggers:

EPA has prepared this fact sheet to help users reduce potential hazards associated with total release foggers. Total release foggers, also known as “bug bombs,” are pesticide products containing aerosol propellants that release their contents at once to fumigate an area. These products are often used around the home to kill cockroaches, fleas, and other pests. Because the aerosol propellants in these foggers typically are flammable, improper use may cause a fire or explosion. In addition to this hazard, failure to vacate premises during fogging or reentering without airing out may result in illness.

There are several video’s that outline the proper use of these tools for pest control (vacate residence, do not use more than on label and ignition sources)  and with all the stories over the last few years its probably time for a detailed guideline on usage. I will add one more item, there is a place for this type of tool within pest control but bear in mind that improper use may make the bug go deeper into the walls or hiding place. This may actually make the situation worse and more difficult if you then must hire a Pest Management Professional.
