What are fleas? What do they look like?
Fleas are a parasitic insect that feeds on the blood of mammals and birds. There are an estimated 2,500 species of fleas in the world. The most common flea species in the U.S. is the cat flea, Ctenocephalides felis, which also infests dogs and can bite humans.
Humans can be bitten by so-called "sand fleas," which usually are found at the beach and in coastal areas. They actually are not insects, but tiny crustaceans, though their bite is similar to that of the cat flea. They do not infest homes.
Adult fleas are about 1/12 to 1/8 inch long, wingless, oval, flat from side to side, and dark reddish-brown. They have six long legs and can jump very high and far, about 200 times their body length. Flea larvae are pale white and measure about 3 mm in length, resembling tiny worms.
What does a flea bite look like on a person (pictures)?
Flea bites look like small red dots. These spots often occur in two to three groups or clusters with redness around them and sometimes a light halo. They tend to bite humans around the feet, ankles, and lower legs.

- Bed bug bites often appear in linear rows and can appear anywhere on the body, whereas flea bites tend to be located in clusters often on the feet and ankles.
- Bed bugs are nocturnal, and like to make their home in your mattress, so bites from these insects usually occur at night when you are sleeping. Fleas are also nocturnal but tend to cling to pets, and are found on furniture, drapery, and carpeting.

- Keep your pets away from animals you know have had fleas recently.
- Keep your pets out of difficult to treat places such as under decks or sheds.
- Mow your lawn frequently and keep the grass short.
- Use a flea comb to check your pet's fur for fleas.
- Keep pet bedding clean and wash in hot water.
- Vacuum carpets, rugs, and upholstered furniture frequently, especially in areas where pets sleep, and under beds, sofas and behind furniture.
- Dust furniture and dry clean curtains and upholstery.
- Use flea preventive medicine on your pet once a month (for example, Advantage, Advantix, Frontline, Revolution, Sentinel, and others). Talk to your veterinarian about the right product for your dog or cat.

How can I tell if I have fleas in my home?
One of the first ways people notice they have a flea infestation is when their dogs or cats start scratching, biting, or licking themselves excessively. You can use a flea comb to check your pet's fur for fleas and flea feces. Flea feces on your pet may look like dot-like insects or flecks of dirt or pepper.
Once fleas have gotten onto pets it does not take long to spread through the household. Once they have infested the home, you may notice fleas hopping on your carpet, furniture, or drapery.
If you suspect that your pet or home may have a flea infestation you can test the dark specks to see if it is flea feces. Moisten the suspected flea feces, and if it turns red or maroon in color, it is flea feces. (Flea feces is comprised of dried blood.) Another quick way to help you check for a flea infestation is to wear long white socks. Fleas like to jump on human's feet, ankles, and lower legs. The insects are dark reddish-brown, and if they jump on you while you wear white socks they will be easier to see.
