Before you check out
Tick-borne illness has tripled in the US in 20 years. Researchers and patient organizations are doing the work that doesn't get the funding it needs.
Donations pooled monthly and sent to a Lyme disease research / patient-advocacy nonprofit. Not tax-deductible.
Built for the new tick
Real tick defense for everyone you take outside.
What we protect against

Lone star, deer, dog ticks — three vectors, multiple diseases, now established across the eastern US and into southern Canada. BITEBACK shields against all of them — one CDC- and Health-Canada-recognised active for you, an EPA 25(b) plant blend for your dog and cat.

Up 4× since 1991. The deer tick is in every state east of the Rockies. We shield against it — for you and your dog.

The lone star tick is rewriting the map — and giving people lifelong meat allergies. Both BITEBACK lines are built to repel it.

Anaplasmosis, ehrlichiosis, Powassan, Rocky Mountain spotted fever. Same defense, broader cover — for the whole household.

Asked our pediatrician at the 18-month visit; she said this brand's on her short list. The label was clear enough that the daycare director cleared it on first read. Two weeks in: no ticks, no daycare drama.

Cedar-based, no peppermint, no citronella. Finally something I can use on the cat without panicking. The dog gets it too — full multi-pet defense.
