Yes, you can use a nit comb for fleas, but it’s not the most effective tool for the job.

A nit comb is designed to remove lice eggs (nits) from human hair. It has very fine, tightly spaced teeth, which can help catch adult fleas in a pet’s fur. However, flea combs are specifically made for this purpose and are usually sturdier and better suited for thicker animal coats.

If you decide to use a nit comb:

Make sure the teeth are strong enough to handle your pet’s fur.
Comb slowly and carefully, especially around the neck, base of the tail, and belly. These are common flea hiding spots. Click here to find out where fleas live in your house!
After each pass, dip the comb in a bowl of warm, soapy water to kill any fleas you remove.
Be gentle to avoid scratching your pet’s skin.

Keep in mind that combing alone will not eliminate a flea infestation. Fleas lay eggs in carpets, bedding, and furniture, so you’ll also need to wash pet bedding, vacuum thoroughly, and possibly use vet-approved flea treatments.

In short, a nit comb can work in a pinch, but a proper flea comb and a full flea control plan will be much more effective.
