Fleas are very tiny insects smaller than 1/8th of an inch. Since they are so small, they are hard to recognize and even notice. A flea infestation will feed on blood from humans and animals and have an amazing jumping ability, despite being wingless. Fleas can jump about 8 inches into the air, making it easy for them to latch onto fur or clothing.
Since they feed on human and animal blood, a flea infestation can be quite bothersome and difficult to fully get rid of. Flea bites will cause an itching feeling for the host that can be very uncomfortable. While fleas are most likely to enter your home through your pets, they will lay their eggs and larvae in different areas around the house, making it difficult to find the source of new fleas for complete flea removal.
