Two of my three cats had awful problems with flea allergies. I spent a fortune on various medications to help (which didn’t) and a £40 flea collar from the internet recommended by my vet made the problem worse at it seemed the cats were allergic to them. I saw an advert for a Bio-collar and I haven’t looked back since. The cats fur is glossy and all their skin problems have cleared up completely. I couldn’t be happier - and neither can my cats!

Why Pet Owners Choose BIO-COLLAR™
NO ONE LIKES UNINVITED GUESTS !
Did you know? 2 in 3 pets in the UK will face flea or tick problems each year — putting them at risk of constant itching, skin infections, and serious illnesses like Lyme disease.
Fleas and ticks don’t just irritate your pet…
They spread bacteria, cause allergic reactions, and can quickly turn into a full home infestation.
Protect your pet — and your home — before these hidden threats become a real problem.
Remove Fleas & Ticks Without Chemicals
A flea may be tiny, but it creates huge problems. Think of it like a grain of sand compared to a football. Despite their size, fleas and ticks multiply fast and spread dangerous diseases.
That’s why the BIO-COLLAR™ uses a balanced blend of citronella, lavender, and lemon eucalyptus oils, slowly releasing them across your pet’s coat. The result: an invisible shield that protects for up to 8 months.
The Safest & Easiest Way To Protect Your Pet!
Every pet parent deals with fleas and ticks eventually…
but most treatments are messy, stressful, or don’t last.
Drops leave residue. Pills are a fight. Sprays smell awful.
And everything needs reapplying.
THE BIO-COLLAR™ changes that.
Put it on once and enjoy up to 8 months of natural, continuous protection for dogs and cats.
No chemicals. No irritation. No weekly routines.
Just simple, gentle, everyday protection.

Brought these before and wasnt really expecting much from them so was happily surprised at how well they do work, my cats are indoor cats but were still getting fleas badly every year , since wearing these collars I haven't had any problems.
Fits well on our Simba our Doberman and works well
Never used before but prefer natural rather than chemical, my girls appear happy with them and do look like they are working! And above all they look pretty in pink! Lol, will buy again
Great product that really works! After 7 months , I saw another natural product that goes onto a Coller ( the one with the ball of liquid ) so I thought I’d try it, and used your Coller to put it on, about a month later I saw black flees on Sam, and realised that your Coller must be the one that was working previously, I immediately ordered some of your products again and as soon as it was fitted, no more flees !! I won’t make that mistake again . Ps I contacted the other suppliers 3 times , no response! Just about says it all !
They do help, but my older one still gets alot of flea dirt etc I'm putting it down to the extremely hot weather that hasn't helped any pet owner I should imagine, otherwise happy
Both dogs wear them. I thought they were working really well until Tuesday when I found a couple of fleas on thr dog in the picture. Regards Gaz
My dog is so much happier and we’ve had no fleas or ticks. Great result all around
First time trying bio collar i love that it has all natural ingredients on it. So far so good 😊👍 highly recommend trying it for ur dog, love that u can bath ur dog without the worries of it not working and it's effective for the 8 months great we product thank you
Your Bio collar is amazing. Milo has been wearing them now for 8 months and never had fleas since he has had them. Incredible 😂
This is the 2nd time I’ve used this & it works, I’ve 2 dogs & they both get along with these quality collars with no adverse reactions
The collar works very well. Never had a flea or tick problem.
Had the coller on a while now so far no sign of fleas. Great alternative
We ordered the flea and tick collar for our cat. We live in a rural crofting area with lots of sheep and ticks are a real problem at this time of year. We were finding ticks on our cat daily but have not had any ticks on him since putting the collar on him so really pleased with the result. Will definitely buy again when it is due to be replaced.
The picture is one of my younger cats Ember wearing her collar (I have 6 cats) and this is our second set of collars after I bought some last year. Fingers crossed not seen any horrible critters on any of them 🤞
Excellent product. So easy to use and does not have any side effects. Will definitely reorder. Have recommended it to friends and family
Definitely works these collars. My dog had fleas regularly until i got his collar. No fleas since i put it on him. Thank you
Monty was continually scratching but now that has stopped thanks to his new collar. He's happy wearing it too.
I’ve been using these collars on my Labrador for a few months now and he’s been completely flea free. Very pleased with the results.
My cat had been scratching non-stop. Since putting this on her, she’s settled right down. Such a relief.
Our spaniel hasn’t had a single tick since wearing this collar, even after long walks in the woods.
I was doubtful at first, but it really does work. My dog is much happier.
We switched from spot-on treatments and haven’t looked back.
My little terrier stopped chewing at her paws within days.
We’d been battling fleas on our Labrador for the best part of the summer. Tried shampoos, sprays and even the spot-on treatments from the vet, but they never seemed to last very long. I decided to give the BioCollar a go as I liked that it’s natural. Within about a week the scratching had reduced massively and now, three months in, he’s completely settled. His coat looks healthier and he seems far more comfortable. Very glad we made the switch.
My cat had dry skin from scratching so much. Since wearing the BioCollar her coat looks healthier and she’s far less irritated. I’m really impressed with how well it’s worked.
We were spending a small fortune on treatments that only seemed to work temporarily. The BioCollar has lasted far longer than expected and has kept our terrier comfortable and itch-free. It’s genuinely been a game changer for us.
I don’t usually leave reviews, but this genuinely deserves one. We’d tried absolutely everything for our Labrador. shampoos, drops, powders and nothing seemed to last. Within about 4 days of putting this collar on, the scratching stopped. It’s now been 4 months and we haven’t seen a single flea. Wish we’d found it sooner.
If you’re unsure, just try it. I nearly didn’t, but I’m so glad I did. My spaniel hasn’t scratched once since wearing it and we walk through fields daily.
We have three cats and keeping on top of fleas used to be a constant battle. Since using these collars we’ve not had a problem at all. They’re easy to fit, don’t have a strong smell and the cats don’t seem bothered by them. It’s saved us a lot of stress (and money).
We’ve got two cats and fleas were becoming a nightmare. Since using these collars, the house feels normal again. No more constant grooming or biting at their fur.
The difference in my dog’s behaviour says it all. He used to wake himself up scratching. Now he sleeps peacefully through the night.
I bought this after a recommendation from a friend at the dog park. My cocker spaniel had been scratching constantly and nothing seemed to fully sort it. Within a fortnight of wearing the collar the difference was obvious. He’s back to being his playful self and not constantly stopping to scratch.
I was sceptical of the “natural” claim, but it genuinely works. No strong smell, no irritation, just protection.
My indoor cat started over-grooming and I noticed little bald patches on her back legs. I felt awful. We fitted the collar and kept up with brushing for the first couple of weeks. Since then her fur has grown back beautifully and she’s far less restless. I’ve not seen a flea since. It’s such a relief not having to use harsh chemicals on her.
My elderly dog seems much more comfortable now. No more biting at his paws or rubbing against furniture.
I’ve recommended this to my sister and two neighbours already. It’s been that good.
We were constantly washing bedding and vacuuming because of fleas. Since using this collar, the problem has completely settled. It’s made life much easier and our dog is clearly more comfortable.
Honestly, if your dog is struggling with fleas, this is worth every penny. Ours is happy and itch-free and that’s all that matters.
We live in a fairly rural part of Yorkshire and ticks are always a worry on long walks. Our spaniel has been wearing the BioCollar for months now and we genuinely haven’t had a single issue. He swims, rolls about in mud and generally lives his best life, and the collar has held up brilliantly. It’s reassuring to know he’s protected.
