Wintergreen oil

InertMin. risk approved

Listed as an inert ingredient permitted in EPA minimum risk (FIFRA 25(b)) pesticide products.

Safety around dogs & cats

Wintergreen oil is almost entirely methyl salicylate, essentially concentrated aspirin. Cats are exquisitely sensitive to salicylates and dogs are also at serious risk, so even small ingested amounts can be toxic. Never apply it to a pet or let one lick treated skin; this is one of the most dangerous oils for animals.
