“When using pesticides for treating flea infestation in your home, remember that these chemicals may have harmful effects to your family, pets, and the environment,” notes Dr. Smith. Most experts agree that home flea treatments are safe as long as you thoroughly read instructions before use and follow the directions carefully. Some must be fully dry before contact to be safe. Others require you to remove food and dishes from treatment areas before application. Be sure you understand your product fully and plan carefully before applying flea control products in your home.
