The answer to 'why is my flea infestation' is that fleas are common household pests that can infest your home and pets. Fleas thrive in warm, humid environments and can quickly reproduce, leading to an infestation. Common signs of a flea problem include seeing fleas on your pets, finding flea dirt (flea feces) on your furniture or bedding, and experiencing itchy bites on your skin.
Flea infestations are often caused by pets bringing fleas into the home, or by fleas living in your yard and finding their way inside. They can also be introduced through secondhand furniture, clothing, or other infested items. Addressing a flea problem requires treating both your home and your pets to fully eliminate the infestation.
