Mosquito sprays are outdoor insecticides that pose a real poisoning risk to pets, especially cats. Most products rely on pyrethroids or pyrethrins, which are highly toxic to felines and can cause serious neurological symptoms in dogs if the pet is sprayed directly, walks through treated areas before they dry, or grooms the product off its fur.
Exposure commonly happens when pets are allowed outside during or immediately after application, when they contact wet foliage or patio surfaces, or when they lick spilled concentrate or residue from their paws. Cats are particularly vulnerable because their livers cannot efficiently break down pyrethroids, so even small amounts can trigger tremors, seizures, or worse.
Keep pets indoors and away from treated areas until the product is fully dry and any label-specified re-entry period has passed. Store concentrates and sprayers securely, clean paws after outdoor walks, and never use dog flea/tick products on cats. For safer mosquito control, consider pet-safe barriers, eliminating standing water, or consulting your veterinarian before applying any repellent.
