Fleas are parasitic insects that live on warm-blooded animals. They can attach themselves to clothing, outdoor materials, and even humans. Their bodies are highly flexible, which allows them to run through hair. Fleas can live in almost any environment and are typically found in areas of the home where people sleep.
Fleas can survive on humans if they have no other warm-blooded host to feed on. Their bites are often red, itchy, and have a raised bump. It is important to thoroughly wash any clothing to get rid of flea eggs. Fleas lay their eggs on dark clothing and can survive for up to 24 hours on clothes.
Adult fleas can survive without a pet for up to 14 days. They feed on blood, and if they are starved, they will seek out humans to feed on. When humans are in a home without pets, fleas will begin to infest bedrooms, where they will feed on their hosts’ blood.
If your home has pets, you must keep these animals inside if you want to keep them out. Fleas will bite people while they are sleeping or sitting. They will try to get your blood before they flee. Fleas don’t like long exposure to humans, so if they don’t get a shower, they may have eggs on their clothing.
