The answer to 'signs of flea' is that common signs of fleas in the home include seeing live fleas, finding flea dirt (flea feces) on pets or furniture, noticing your pets scratching or biting themselves excessively, and seeing small red bites on your own skin. Fleas are small, dark-colored insects that can jump long distances and feed on the blood of humans and animals.
Fleas are often brought into the home by pets, but can also come in on clothing, furniture, or other items. They can quickly multiply and infest a home if not addressed. Prompt action is important to get rid of a flea problem before it becomes worse.
