Fleas are parasites that feed on the blood of any warm-blooded body. The most common species is the cat flea, which often feasts on cats, dogs and humans.


Fleas transport themselves on rodents and other mammals. They infest both household pests and wild animals. Fleas use their powerful legs to jump as high as 8 inches vertically and 16 inches horizontally.


Fleas usually remain on their warm-blooded hosts at all times. They can also be found on shoes, pant legs, or blankets, which can transfer the fleas to new environments. They are often found infesting opossums, raccoons, and skunks in urban settings.


Fleas are the most common transmitter of the rare Bubonic Plague. They also transmit the bacterial disease murine typhus to humans through infected rats. Their saliva can cause serious Flea Allergy Dermatitis in pets, and their debris has been reported to cause similar allergic reactions in humans. Fleas can also transfer tapeworms and cause anemia in pets. Flea bites commonly cause painful, itchy red bumps.


Clean and vacuum frequently to help remove flea populations and prevent the laying of eggs. Keep your lawn groomed to avoid rodent habitation. Protect pets by keeping them on a leash when outside, bathing, and grooming pets regularly, visiting a veterinarian annually and using flea treatments according to the directions. It is important to hire a pest professional to rid your home of rodents and fleas.
