Ticks & fleas: checking, prevention and control

In short

Fleas and ticks are common external parasites that cause itching and skin disease and can transmit illness. Because most of a flea problem lives in your home — not on your pet — control means treating the pet and the environment, with vet-chosen, species-appropriate products used consistently. If you've just found a tick attached to your pet, see our step-by-step removal guide.

  • Fleas cause itching, skin allergy and tapeworm; ticks can transmit serious disease.
  • Only about 5% of a flea population lives on the pet — the rest (eggs, larvae, pupae) are in the home.
  • Check regularly with a flea comb; confirm fleas with the 'flea dirt' test.
  • Never use dog products on cats — some (e.g. permethrin) are toxic to cats. Choose prevention with your vet.

Ticks and fleas — what's the difference

Fleas are tiny, fast-moving insects that live in the coat and feed on blood; they multiply quickly and most of their life stages live in your home. Ticks are larger, spider-like parasites that attach to the skin to feed over days and can transmit disease while attached. Both are picked up outdoors and from contact with other animals — and even indoor-only pets can be exposed via people, other pets, or open doors and windows.

How to check your dog or cat

Use a fine-toothed flea comb over the neck, back, belly and especially the base of the tail. You may see live fleas or small black specks (“flea dirt”). To confirm flea dirt, brush the specks onto a damp white tissue: if they smear reddish-brown, that's digested blood — a confirmed flea infestation.

For ticks, run your hands slowly over the body after outdoor time, checking ears, face, neck, armpits and between the toes, where ticks like to attach. If you find one attached, don't panic — see our removal guide below.

Why the home matters: the flea life cycle

Adult fleas on your pet lay eggs that fall into carpets, bedding and cracks. These hatch into larvae, then form hardy pupae that can survive weeks to months before emerging. Because only about 5% of the flea population (the adults) is on your pet at any time, treating the pet alone won't clear an infestation — you also need to vacuum thoroughly and often, wash bedding on a hot wash, and keep every pet in the home on treatment. Fleas may keep appearing for weeks as pupae hatch out, so control must continue for several months.

Tick-borne disease: warning signs

Ticks can transmit serious infections. After a bite, watch your pet over the following days and weeks for lethargy, fever, loss of appetite, pale gums, weakness, lameness or reluctance to move. These can appear well after the tick is gone, so keep an eye out and see your vet promptly if they develop. Fleas, meanwhile, commonly cause flea-allergy skin disease and can transmit a tapeworm if swallowed during grooming.

Prevention, at a high level

Effective, modern prevention comes as spot-ons, tablets or collars — chosen for the species, weight and lifestyle of your pet, and used consistently (often year-round in warm climates). We don't recommend specific products or doses here; that's a decision to make with your veterinarian, who can match the product to your pet and local parasite risk. Combine prevention with regular checks and environmental control for the best results.

Dogs vs cats

The most important difference is product safety. Never use a dog flea/tick product on a cat — some contain permethrin, which is highly toxic to cats. Cats are also sensitive to many essential oils (tea tree, eucalyptus and others), so avoid 'natural' oil-based remedies on cats entirely. Always read the label, use species-appropriate products, and treat every pet in the household together.

India-specific considerations

Warm, humid conditions across much of India mean ticks and fleas can be active for most of the year, so consistent, year-round prevention is often advised. The brown dog tick is widespread here and is associated with canine tick-borne diseases such as ehrlichiosis and babesiosis. Please avoid traditional 'home' tick methods — kerosene, petrol, oils or burning — which can harm your pet and raise disease risk without removing the parasite safely.

Safe control — and what to avoid

Do

  • Use vet-recommended, species- and weight-appropriate prevention, consistently.
  • Check your pet regularly with a flea comb and after outdoor time for ticks.
  • Treat every pet in the home together, and continue for several months to break the flea cycle.
  • Vacuum floors and furniture often and wash bedding on a hot wash.
  • Remove any attached tick promptly and correctly (see the symptom guide).

Don't

  • Use dog flea/tick products on cats — some are toxic to cats.
  • Apply essential oils, kerosene, petrol or other home remedies.
  • Burn a tick or hold a flame near your pet.
  • Treat only the pet and ignore the home — most of a flea problem is in the environment.
  • Stop prevention the moment you stop seeing fleas — pupae keep hatching.

When to see a veterinarian

Book a visit

Parasites are usually manageable, but some situations need veterinary help.

  • Persistent itching, hair loss, scabs or a skin infection
  • A heavy infestation, or a tick you can't fully remove
  • In the days-to-weeks after a tick bite: fever, lethargy, pale gums, weakness or lameness
  • Pale gums or weakness in a small kitten or puppy (possible anaemia from heavy fleas)
  • Any illness after applying a parasite product — take the packaging with you
I found a tick — what to do

Frequently asked questions

I found a tick on my pet — what do I do right now?

See our step-by-step tick guide: remove it promptly with fine-point tweezers or a tick tool, gripping close to the skin and pulling straight out, then clean the area and watch your pet. Never use oils, kerosene or a flame.

Why do I still see fleas after treating my pet?

Because most of the flea population is in your home as eggs, larvae and pupae. Pupae keep hatching for weeks. Keep every pet on treatment, vacuum often, and wash bedding — it can take a few months to fully clear.

Do indoor cats need flea and tick prevention?

Often yes. Fleas and ticks can come in on people, other pets, or through doors and windows. Your vet can advise what's appropriate for an indoor cat in your area.

Are 'natural' flea remedies safe?

Many aren't — several essential oils are toxic to cats, and unproven remedies can delay effective control. Stick to vet-recommended products chosen for your pet's species and weight.

Can fleas and ticks affect my family?

They can bite people and some tick-borne diseases have human relevance. Good pet prevention, environmental control and prompt tick removal reduce the risk for everyone.
