Fleas are tiny parasitic insects that feed on the blood of mammals and birds. You are most likely to encounter them in your home if you have a pet that unknowingly brings them inside. These parasites may be tiny, but they can multiply quickly and create a serious problem for you and your pets. They also multiply quickly, so you need to be able to spot a flea infestation and deal with it quickly if you want to keep it from getting out of control.
What Do Fleas Look Like?
Fleas are small wingless insects with three pairs of legs. Adults are only about 1/8 of an inch long, which makes them very hard to spot with the naked eye. They also move quickly and have flat bodies that make it easier for them to navigate an animal’s fur coat. They are typically reddish-brown in color.
Are Fleas Harmful?
Fleas usually don’t pose a health risk to humans, but their bites can cause itching that can lead to infection. Fleas do occasionally carry parasites such as tapeworms, and it is possible to develop an allergy to flea bites.
