Do indoor cats need flea treatment?

Yes. Fleas enter homes on shoes, other pets or previous occupants. Year-round prevention is simpler than treating an established infestation.

How often should I worm my dog in the UK?

Adult dogs typically need worming every 1–3 months depending on product and lifestyle. Puppies need more frequent schedules — follow your vet's plan. Lungworm prevention is essential in affected UK areas.

Are ticks a problem in the UK?

Yes — ticks are active whenever temperatures are above about 4°C. They transmit Lyme disease. Check pets after walks and use vet-recommended preventive products.

Parasite Prevention for UK Pets — Fleas, Ticks & Worms

Published 1 June 2026Last updated 25 June 20261 min read

Quick answer

UK pets need year-round parasite control tailored by species and lifestyle. Fleas, ticks and worms (including lungworm in dogs) are preventable with vet-prescribed or vet-recommended products — never use dog-only treatments on cats.

Fleas

Treat all pets in the household simultaneously and wash bedding at 60°C. Environmental sprays may be needed for heavy infestations. Prevention is easier than eradication.

Ticks

Use appropriate preventive products. Remove attached ticks with a twisting tool — do not burn or squeeze. Monitor for Lyme disease signs after bites in endemic areas.

Worms

Pet	Key worms
Dogs	Roundworm, tapeworm, lungworm
Cats	Roundworm, tapeworm
Rabbits	Pinworm, E. cuniculi (discuss with vet)

Puppies and kittens need veterinary worming schedules from birth.

Buying parasite products

Purchase from your vet or pharmacy with veterinary approval. Many online products are unsuitable or counterfeit. The BVA advises products prescribed for your pet's weight and species.
