Flea & Lice Comb: How to Detect Fleas, Eggs & “Flea Dirt” (Dogs & Cats)
A good flea & lice comb is the quickest way to confirm if your dog or cat has fleas—or if you’re just dealing with dry skin and dust. Ultra-fine teeth catch adult fleas, eggs and the tell-tale “flea dirt” (dark specks that smear red on damp tissue). Below: how to use a comb properly, where to check, and what to do next.

Why a flea & lice comb belongs in your kit
- Fast detection: find fleas before an infestation takes hold.
- Egg & flea-dirt check: confirm what you’re seeing in minutes.
- Skin scan: teeth reach the skin to spot irritation, bites or scabs early.
- Daily habit: quick sweeps during peak season keep you in control.
How to use a flea & lice comb (step-by-step)
- Prep: Have white tissue/kitchen roll and a small bowl of water ready.
- Work in sections: neck, behind ears, along the back, tail base, inner thighs, armpits.
- Comb against the lay of the coat in short strokes so teeth reach the skin.
- Wipe on white tissue every few passes. Add a drop of water—flea dirt smears red/brown.
- Check the comb for moving specks (adults) and tiny white ovals (eggs).
Hot-spots to check
- Behind ears & collar line (warmth and shelter)
- Tail base & lower back (flea favourite)
- Groin, armpits, inner thighs (thin hair = easy bite sites)
Found fleas or flea dirt—what next?
- Comb daily to reduce adult numbers and monitor progress.
- Wash bedding & soft furnishings; vacuum carpets and upholstery thoroughly.
- Speak to your vet about an appropriate preventative/treatment plan (topical/oral/environmental).
Flea vs. dry skin: a quick check
Dry skin flakes are light and don’t smear red when wet. Flea dirt is darker, pepper-like and leaves a rust-red smear on damp tissue.
Why we recommend a pocket comb you’ll actually carry
- Always with you: credit-card size fits wallets, phone pouches and lead bags.
- Dual-purpose: use the fine side for detection; use the grooming edge for daily tidy-ups.

Can I use the comb on kittens/puppies?
