Wondercide Flea & Tick Spot On for Dogs is a plant-based topical repellent infused with peppermint that protects against fleas and ticks for up to 1 month and mosquitoes for up to 1 week. Each box contains 3 tubes — a full 3-month supply — formulated for small dogs under 35 lbs.
Designed as a preventive layer of protection, not a treatment for active infestations. Apply one tube monthly to repel fleas, ticks, and mosquitoes before they become a problem.
What separates Wondercide Spot On from the crowded flea-and-tick shelf is the combination of what's in it and what isn't. Most conventional spot-ons rely on synthetic pyrethroids or isoxazolines — chemical classes that are effective but come with increasing scrutiny, particularly for small dogs and households with cats. Wondercide's formula is built around steam-distilled peppermint essential oil, lab tested to repel fleas, ticks, and mosquitoes without those ingredients. For small dogs especially, where dosing sensitivity is a real concern, that distinction matters. The Small size is dosed for dogs under 35 lbs, and at one tube per month the 3-tube box covers a full season. One thing to be clear on: this is a repellent, not a knockdown treatment. If your dog is already scratching from an active flea infestation, pair it with Wondercide's Flea & Tick Spray for pets, home, and yard to address the existing population first — then transition to monthly Spot On for prevention going forward. Used correctly, it's one of the cleanest options in its category.
