How to Get Rid of Flea Dirt on Cats and Dogs
Flea dirt is a sign of fleas. So the first thing to do is to treat your pet for fleas. Then, to prevent further production of flea dirt, your veterinarian can advise on the best product for your cat or dog.
Suppose your cat or dog has a heavy build-up of flea dirt. In that case, you could also consider removing it, but remember this isn’t always necessary as it will go away eventually as your animal grooms themselves.
To remove flea dirt, there are a few options. Firstly you could consider using a flea comb to brush the coat. This can remove flea dirt as well as any residual fleas. However, using a flea comb requires a patient animal who doesn’t mind sitting for a long time.
It is not recommended to use a flea comb on pets with long, matted, or knotted fur as it can be painful.
You can run the comb through the fur and clean it off using gentle strokes before starting a new stroke. Start from the neck and work down to the tail. Make sure you cover the entire body. The benefit of using a flea comb is that there are no chemicals or bathing required, which may suit some animals with sensitive skin or cats that typically detest water.
The second option is to bathe your pet. Again, you can use flea shampoo or regular shampoo but make sure to check with your veterinarian first as some topical flea products need to stay on the skin for a few days before bathing for them to work. Also, it may not be recommended to use flea shampoo and other flea products at the same time.
Once you’ve got it all clear, you can set your pet up for a regular bath. Make sure that you thoroughly rub your fingers into their coat, as the flea dirt will be located close to their skin. Rinse well and enjoy a freshly cleaned pet.

How to Perform an at-Home Flea Dirt Test
If you notice some black flakes in your pet’s fur, you might be unsure if it is regular dirt or flea dirt; luckily, there is a quick at-home test you can perform to find out.
Firstly, use a fine-toothed comb to brush through the fur and collect some of the dirt. Secondly, grab a paper towel and lightly wet it so that it is damp. Then, distribute some of the dirt from the comb onto the damp paper towel. Watch the dirt as it dissolves into the paper towel.
Flea dirt contains blood, so when it is wet, it will turn the paper towel a reddish-brown color, the color of blood. Regular dirt will not dissolve as easily and won’t turn the paper towel a reddish-brown color. Another option if you don’t have a comb is to press the damp paper towel onto the dirt to pick some up and examine it in the same way as above.
Once you know that the dirt is flea dirt, you can plan to treat your pet accordingly.
Flea dirt is the waste product that fleas produce when they feed on our pets. Although flea dirt can seem gross, it’s essential to know what to look for and what to do about it to prevent a problem from occurring.
