Take the 60-second check
Why isn't your flea treatment working?
A 60-second self-check based on advice from UK veterinary charities. Answer 6 questions and we'll show the most likely reasons — and what to do next.
Question 1 of 6
Which pet are you treating?
How do spot-on treatments work?
Bite = die
If a flea bites your pet, it dies. If it doesn't bite, it won't. Not every flea you see has bitten.
100 days
Adult fleas can survive up to 100 days without feeding on blood.
1000s of eggs
Before treatment, female fleas may already have laid thousands of eggs in your home and on your pet.
95%
of fleas live in your home — not on your pet.
Fleas jump off to lay eggs in warm, dark places like carpets, sofas and clothing. Eggs laid on your pet fall off too.
Prevent re-infestation
- • Break the cycle by eliminating eggs, so new fleas can't hatch.
- • Apply flea treatment monthly as prevention.
Break the cycle
- • Vacuum regularly — under furniture and along skirting boards.
- • Wash your pet's bedding on a hot cycle.
- • Comb your pet to remove adult fleas and eggs.
Applying a spot-on, properly.
- 1
Part the fur so the treatment covers as much skin as possible.
- 2
Apply at the back of the neck, in front of the shoulder blades, so your pet can't lick it off.
- 3
Keep your pet dry and stop them rolling on carpets or bedding afterwards.
