Flea Sprays/Foggers

Sprays and foggers are designed to kill fleas, flea eggs and larvae inside the home or other enclosed area, without posing a health risk to people, pets or indoor plants. Sprays and foggers should include a quick-kill ingredient to eliminate adult fleas, and an insect growth regulator (IGR) to kill eggs and larvae before they develop. Be sure to remind customers to read all labels carefully before applying a premise spray or fogger.

Air-conditioning and air-exchange systems in the house should be shut off completely when premise sprays and foggers are applied. This will ensure that the full strength of these products remains in the house. It will also prevent these insecticides from being re-circulated in the house through the air systems later on.

Yard Sprays are also an essential part of a flea control program, these sprays eliminate fleas, flea eggs and larvae from a dog’s outdoor environment. Yard sprays are most effective when they are microencapsulated to provide a gradual time-release of their active ingredients. Before using a yard spray, locate flea "hot spots" in the yard, and remove debris such as twigs and leaves from the area. Also remove all debris from porches and garages, since this can afford protection to fleas.

Do not use a yard spray in the home, since it is unsafe in an indoor environment. Also, indoor premise spays and foggers should not be used outdoors, since they will quickly lose their effectiveness when exposed to sunlight and moisture.
