How Visible Are Fleas?

Fleas are small, wingless insects, which are often not very visible to the naked eye. They are less than 1/16th of an inch long, and their bites are highly irritating. Fleas can also carry a tapeworm, making them highly dangerous. This parasite goes through a life cycle that makes it vital to identify and treat it effectively.

Fleas often lay their eggs in carpets and rugs, making them difficult to detect. If you have dark carpeting, they may be even harder to see. Flea eggs can also be found in cracks between wood floorboards. Using a flea comb will help you identify if you have a flea problem.

Flea bites look like small, red bumps, usually with a ring of red around the center. Fleas tend to live on warm, folded skin, and on legs and ankles. Flea bites are often painful and can leave a scab or red rash.

Adult fleas are about an eighth of an inch long and reddish brown. They are wingless and move very quickly. Unless there is a severe flea infestation, you may not even notice them. Fleas have six legs, including two hind legs that are larger than the forelegs. Their forelegs allow them to leap eight inches high, while their hind legs enable them to jump up to 16 inches.

It is also important to check your pet regularly for signs of flea bites. Fleas are very small and difficult to see, so keep a close eye on their behavior to spot them early. If you notice a flea on your pet, you should be sure to treat it accordingly.
