Pros & Cons of Do It Yourself Flea Bombing

A flea bomb, also called a fogger, functions as a total-release aerosol pesticide homeowners may purchase at various retailers. Normally a combination of permethrin, a synthetic chemical that functions as a neurotoxin, and methoprene, a growth regulator, flea bombs typically do not negatively affect humans. Permethrin can be harmful to cats, as it may cause toxicosis.

The permethrin kills hatched fleas while the methoprene (insect hormone mimic/insect growth regulator) halts new fleas from hatching. Flea bombs release the chemical combination as a mist, which then disperses and settles around the infested room. Homeowners should not reenter the home for up to four hours (see and follow product labeling) after using a flea bomb, and properly ventilating the house is a must.

Though relatively inexpensive and seemingly easy to use, severe flea infestations should be handled by trained pest control professionals. Flea bombs do not always reach all areas allowing for possible re-infestation. Inadequate ventilation or failing to clean treated areas properly may lead to food contamination in prep surfaces after treatment.

Precautions & Removal

Do-it-yourself flea bombs may present a risk of fire, as homeowners must remember to turn off all potential ignition sources in homes before use including all electrical sources/appliances and pilot lights for gas appliances. Turning potential ignition sources back on too soon may also lead to fire.

Homeowners must also be aware of the need to repeat whole-house treatments like flea bombs in 10 to 12 days to ensure that initial fumigation proved successful. A trained pest control professional neutralizes all possible areas of contamination, including those indoors, outdoors, deep in carpet, and in between counters, cupboards, and baseboards.
