Fleas are tiny, wingless parasites that feed on the blood of a warm-blooded host. Fleas become problematic when they attach to pets like cats and dogs. The most common fleas are dog fleas and cat fleas. Adult fleas are between 2-3mm long and are typically reddish-brown in color.
Female fleas lay eggs loosely in the hair of the host animal, typically cats and dogs. However, a number of animals and even humans can have fleas. The eggs drop off and hatch in 2-14 days into small, hairy, worm-like larvae. Flea larvae can be found in the kennel or cage of your animal, along baseboards, in carpet, or even in furniture. Fleas usually live up to 3 months in which a female can produce up to 500 offspring in that time.
Flea bites are the most irritating aspect of these pesky insects. These bites cause red, swollen spots that are extremely itchy. Bites are usually clustered together and can remain itchy for several weeks.
