How to: Check your pet for fleas

Watch now to know what you need, where to look, and what to do next.

Where to look for fleas on your pet

Even if your pet has an active infestation, it can still be difficult to spot fleas with your naked eye. Here are two areas where it may be easier to find visual proof:

Ears and rears: Fleas often settle down to feed in furry areas like necks, ears, and hindquarters.
Nooks and crannies: Fleas enjoy hiding in the armpits and groin, at the base of the tail, and inside folds of skin.

Use a flea comb and a damp paper towel to find fleas

Get settled with your pet someplace where you can sit safely and comfortably together. It can help to have a friend nearby to help hold or distract your pet.


  1. Use your flea comb to gently comb your pet’s hair from back to front. Try to get a good look at their skin.

    As you comb their hair, look for small, red-brown bugs (living or dead) and small black flecks of flea dirt (a fancy word for flea poop).

    Also keep an eye out for areas of red, irritated, or broken skin from scratching. (Sore skin can need veterinary help even if you don’t find fleas!)

  2. If you find little black specks, you may not be sure if they’re flea dirt or just plain dirt. The test is to put them on your damp paper towel. Because flea dirt is digested blood, it will turn reddish brown when wet. (Yuck!)

  3. When you’re done, consider giving your very good pet a little treat for their cooperation. And make sure to wash your hands thoroughly!

    See fleas, flea dirt, or raw or sore skin? Reach out to your veterinary team about solutions, like year-round flea and tick prevention for your pet or ways to help their overall itchiness.

If you see a flea or flea dirt, assume your pet has fleas

A female flea can lay up to 50 eggs a day. So even if you only found a few dead fleas, or a few bits of flea dirt, it’s pretty likely your pet still has active fleas — and that other pets in the house do, too.

In addition to treating your pets, you’re probably going to need to treat your house as well. Fleas can hide in your home where pets hang out even during the winter months.
