UK Flea & Tick Guide for Dog and Cat Owners
Last updated: 1 October 2026 · New guides added every Friday
Fleas and ticks are a year-round reality for UK pets. Ticks wait in the grass and bracken on our walks, and central heating lets fleas breed indoors right through winter. This page brings together all our practical, UK-focused guides in one place, so you can find the answer you need quickly.
Ticks: the essentials
Ticks are common on UK dogs: in the University of Bristol's Big Tick Project, about 30% of dogs checked at the vet were carrying at least one. The RSPCA puts peak tick season at March to October, and the highest rates were found in Scotland, the South West of England and East Anglia.

Fleas: the essentials
Most of a flea problem isn't on your pet at all: the RSPCA says 95% of flea eggs, larvae and pupae live in the home environment. That's why fleas often seem to come back after treatment, and why indoor pets can still get them.

Quick answers
When do UK pets need flea and tick protection?
UK pets need flea protection all year, because central heating lets fleas breed indoors in winter, and tick protection at least from March to October, when the RSPCA says ticks are most active. Ticks can still appear on mild winter days, so many owners protect their pets all year round.
What's the most important everyday habit?
The most useful habit is a quick check of your dog after every walk in grass, bracken or woodland, plus regular vacuuming and hot-washing pet bedding at home. Together they catch ticks early and stop fleas building up in carpets and furniture.
When should I see a vet?
See your vet if your pet has sore or bald patches, constant scratching, or seems unwell after a tick bite (tired, off food, limping or with swollen joints). Always ask your vet before combining treatments, and never use a dog flea product on a cat unless the label says it's suitable for cats.
Long-lasting, plant-based protection
If you'd rather avoid monthly spot-ons, the BIO-COLLAR™ is a plant-based essential oil collar designed to help keep fleas and ticks away for months, with no monthly routine. It works best as prevention, alongside regular checks and a clean home.
