Flea sprays are insecticides designed to eliminate fleas and their eggs from pets and home environments. They typically contain active ingredients that target the nervous system of fleas, leading to their death. Many flea sprays are safe for use on pets, but it's essential to follow the instructions carefully to avoid harming your animal or the environment. These sprays can be applied directly to pets or used in areas where fleas are likely to hide, such as carpets and furniture. Regular use of flea sprays can help control infestations and prevent future outbreaks, making them a valuable tool for pet owners dealing with flea problems.
