Flea bombs treat indoor flea infestations through indirect application of chemicals. They are designed to be left alone to release pesticides into the room and kill the fleas.
While flea bombs sound like an effective solution for indoor flea infestations, their chemicals often do not reach hidden or sheltered areas, such as the spaces beneath furniture or the interiors of closets and cabinets. These spaces can become a refuge for the fleas. Fleas in these protected areas will be unaffected by the flea bomb and therefore not controlled. Flea bombs also do not address outdoor infestation or animal infestation. One of the most critical parts of a successful flea control program is addressing the source of the fleas. Pets should be treated with an appropriately labeled product homeowners can purchase from their veterinarian. If the pet is the source and not treated, it will lead to a continuation of flea activity and likely failure of the other treatments. The areas outside where the animals or wildlife reside also need to be treated, or else the homeowner may pick up fleas when outside the home.
Flea bombs also leave behind a residue on surfaces and can contaminate exposed food and food preparatory surfaces. Lastly, certain stages of the flea’s life cycle are not likely to be affected. Pupae and adults inside the cocoons are not as affected as other stages. For these reasons, a flea bomb is not considered an effective or recommended solution.
