Fleas on Cats: How to Get Rid of Them Naturally

Published September 2026 Β· 7 min read

Excessive scratching, tiny black specks in the coat, unusual restlessness: your cat probably has fleas. Here's how to get rid of them effectively, without resorting to harsh pesticides.

How do I know if my cat has fleas?

Run a fine-toothed comb through the coat, especially at the base of the tail and around the neck, over damp white paper. Small black specks that turn reddish on contact with water are flea droppings β€” a reliable sign even without spotting the insect itself.

πŸ” Good to know: adult fleas make up only 5% of an infestation β€” the rest (eggs, larvae, cocoons) hides in the environment: carpets, sofa, bedding.

5 steps to get rid of them naturally

1
Comb your cat daily with a flea comb to mechanically remove adult fleas.
2
Wash all fabrics at 60Β°C (bedding, cushions, blankets) to kill eggs and larvae.
3
Vacuum thoroughly on carpets, rugs and sofas, emptying the bag immediately afterwards.
4
Use diatomaceous earth on fabrics that can't be washed β€” it dries out fleas without chemicals.
5
Fit a natural repellent collar to prevent any new fleas settling in over the following weeks.

How long does it take to fully eliminate fleas?

Generally allow 3 to 6 weeks to fully break the flea life cycle, as eggs and cocoons can survive several weeks in the environment even after treating the cat itself.

⚠️ Warning: treating only the cat without treating the environment (carpets, sofa, bedding) explains most failures β€” fleas come back from eggs already present in the home.

How to prevent a new infestation?

Once the infestation is cleared, ongoing prevention is key β€” a natural repellent collar worn continuously stops new fleas settling in, without having to repeat the whole treatment process each time.

Frequently asked questions

Can cat fleas bite humans?

Yes, occasionally, especially with a large infestation β€” bites usually appear on the legs and cause small localised itching.

Can an indoor cat get fleas?

Yes, fleas can be brought in by another pet in the household, on clothing, or already present in a home before the cat arrives.

Should all pets in the household be treated at the same time?

Yes, absolutely β€” treating just one animal while another still carries fleas will only keep reinfecting the first.
