Wondercide Flea & Tick Collar for Dogs Peppermint Small/Medium

Wondercide Flea & Tick Collar for Dogs is a plant-based repellent collar infused with peppermint that protects against fleas and ticks for up to 4 months and mosquitoes for up to 1 month. The Small/Medium size fits dog necks measuring 9.5" to 21" and was previously listed as the One Size Fits All collar.

Designed as a preventive layer of protection, this collar repels bugs before they become a problem — not a treatment for active infestations. Pair with Wondercide Flea & Tick Spray for complete coverage.

Benefits

• 4-month flea & tick repellent — continuous protection against fleas and ticks for up to 4 months
• Monthly mosquito protection — repels mosquitoes for up to 1 month
• Plant-based formula — powered by peppermint essential oil, no synthetic pesticides
• Adjustable fit — fits necks 9.5" to 21", suitable for most small and medium breed dogs

Great For

• Dog owners looking for a plant-based alternative to conventional flea collars
• Dogs that spend regular time outdoors, hiking, or in tick-prone environments
• Pet owners who want continuous protection without monthly topical applications
• Multi-pet households already using Wondercide sprays who want an added layer of coverage

Pawstock Insights

The Wondercide Flea & Tick Collar occupies a genuinely useful middle ground in flea prevention: longer duration than a monthly spot-on, simpler application than a spray routine, and none of the synthetic chemicals found in conventional collars like Seresto. At 4 months of flea and tick repellency per collar, it's one of the longest-lasting plant-based options available in this format. The peppermint essential oil formula works by continuously releasing scent that deters fleas, ticks, and mosquitoes from approaching — which means consistent wear is key to getting full protection. A couple of things worth knowing before you buy: this collar repels, it does not kill. If your dog is already dealing with an active flea problem, start with Wondercide's Flea & Tick Spray for pets, home, and yard to knock down the infestation first, then transition to the collar for ongoing prevention. Also note that Wondercide recently consolidated their sizing — what was previously called One Size Fits All is now labeled Small/Medium, fitting necks from 9.5" to 21". If you're shopping for a larger dog, the Large size fits necks 13.5" to 26".

Usage & Application

Buckle collar around dog's neck with enough room to fit two fingers between collar and skin. Wear continuously for best results — remove only for bathing or swimming. Replace every 4 months for ongoing flea and tick protection. For active flea infestations, use Wondercide Flea & Tick Spray for pets, home, and yard as directed before switching to collar-based prevention.
