The answer to 'flea in my house' is that fleas are a common household pest that can infest homes and cause problems for both people and pets. Fleas are small, wingless insects that feed on the blood of their hosts, which can lead to skin irritation, allergic reactions, and the potential spread of diseases.
Common causes of flea infestations include bringing in pets that have fleas, exposure to infested areas, or the presence of wildlife or rodents that can carry fleas. Symptoms of a flea problem may include seeing the fleas themselves, experiencing itchy bites, or finding flea dirt (flea feces) on your pet or in your home.
