The answer to 'why is my flea invasion' is that fleas are a common household pest that can quickly infest your home and pets. Fleas thrive in warm, humid environments and can reproduce rapidly, leading to a full-blown flea infestation if not addressed quickly. Common causes include pets bringing fleas indoors, adult fleas emerging from pupae in the home, or an existing flea population in the yard or neighborhood.
Symptoms of a flea infestation include seeing live fleas on your pets or in your home, finding flea dirt (flea feces) on your pets or in your home, and experiencing itchy bites on your skin. Flea infestations can also lead to health issues for pets, including skin irritation, anemia, and the transmission of tapeworms.
