How Itch Flea Treatment works

  • Flea Treatment Ingredients

    Attacks the central nervous systems of fleas and kills them within 24 hours and ticks within 48 hours. Sucks to be you, fleas.

    (S) Methoprene 
    Directly penetrates flea eggshells, preventing flea larvae and pupae from developing. So long, suckers.



  • Where do fleas come from?

    Did you know that just 5 fleas on an untreated pet can lead to more than 1 million eggs infesting your home in only 4 weeks*? Gulp. But where do fleas come from?

    Most fleas come into contact with your cat or dog from the environment around them. From gardens, to the pub, the park and street, it can feel like nowhere is safe from the blighters.

    Wildlife such as foxes, hedgehogs, birds, squirrels and rabbits can all be flea-carrying culprits, bringing them into your garden ready for your pet to pick up.

    Anyone who comes into your home (human and pet alike) can unknowingly carry fleas in with them too.

    Believe us when we say prevention really is better than cure. Flea eggs can lurk within your home for up to 5 months before hatching. So even if you think you have treated a flea infestation, it could still come back unexpectedly.

    Break the cycle with Itch - the UK's personalised flea treatment subscription for cats and dogs. Our Itch Flea spot-on treatment attacks fleas at EVERY life stage.

    *Based on an untreated pet having 5 fleas not being groomed off, each laying 50 eggs per day, developing into new fleas in 14 days and new fleas jumping on and laying more eggs.

  • How to tell if your pet has fleas

    Symptoms of flea infestation in your pet can include itching, scratching, visible flea dirt, hair loss from overgrooming or skin irritation. It can also include mysterious insect bites popping up on you, as well.

    5 fleas on an untreated pet can lead to 1 million + eggs infesting your home in as little as 4 weeks*. That’s why it’s important you give your cat their flea treatment every month to stop any unwanted lodgers moving in.

    Top tip: If you think you’ve found flea dirt, run a damp cotton wool pad over it. If the dirt turns red, those fleas aren’t dead. This means you’re dealing with a live infestation.

    Our double action, spot-on flea treatment for cats and dogs, Itch Flea, kills adult fleas within 24 hours, halts all other flea life stages in their tracks and stops any new fleas from infecting your pets, protecting them until their next monthly flea treatment. Plus it kills ticks and lice!

  • How to get rid of fleas (and prevent them coming back!)

    Itch Flea Treatment for cat and dogs is super easy to apply - once the solution from the pipette is applied to your pet’s skin between their shoulder blades, you can put your feet up, safe in the knowledge they’ll be protected for the next 4 weeks!

    To kill fleas and stopping more developing, our spot-on formula is the best flea treatment:

    ✓ Kills fleas already living on your cat within 24 hours
    ✓ Kills any new fleas that jump onto your cat or dog, any time in the next month
    ✓ Prevents eggs and larvae developing
    ✓ Kills adult ticks attached to your cat and lice within 48 hours
    ✓ Protects your pet and your home

  • Why use spot-on flea treatment?

    Using a flea spot-on treatment is a super quick and easy way to get rid of fleas and keep your pet and home flea-free.

    For some pet parents, giving their four-legged friend a flea tablet can be a real ordeal. Spare yourself (and your pet) the stress by treating them with a flea treatment that is applied to your cat or dog's coat instead.

    As we always say, prevention is better than cure. Itch Flea treatment attacks fleas at all life stages to help keep your pet cat or dog (and your home) flea-free. This means you can avoid needing to resort to flea bombs. It’s a real faff needing to evacuate your home for hours while it works, not to mention adequately airing out the space after so it’s safe for pets and humans alike to go back inside!

I have seen so many dogs and cats suffering because they weren’t treated for fleas and worms in time. Not only that, it can be dangerous for families too. That’s why I love the Itch personalised flea plan. It makes it so easy to protect your pet and never miss a treatment.
