Is Household Flea & Tick Spray Toxic to Dogs and Cats?

Toxic - Danger

This can be dangerous at any amount. Contact your veterinarian or poison control immediately if your pet is exposed.

Household Flea & Tick Spray is a pesticide product designed to control pests such as fleas and ticks. This product contains the active ingredient Diazinon at a concentration of 0.5%. Diazinon is an organophosphate insecticide. Products containing this chemical are generally used to manage pest infestations in a household environment. The application typically involves spraying infested areas, including pet bedding, carpets, and upholstery, where fleas and ticks are likely to reside. However, Diazinon has significant toxicity concerns, especially for pets like cats and dogs. In pets, exposure to Diazinon can result in symptoms of organophosphate poisoning, which includes salivation, diarrhea, tremors, breathing difficulties, and in severe cases, can be fatal. Cats are particularly sensitive to Diazinon and can exhibit life-threatening symptoms even at low exposure levels. For dogs, while slightly more resistant, toxicity can still occur, especially with repeated exposure or ingestion. Due to these risks, pet owners must exercise caution when using any pesticide containing Diazinon, ensuring that pets are not present during application and avoiding treated areas until the product has fully dried and any odors have dispersed. Always follow the manufacturer's guidelines and consider consulting a veterinarian before using such pesticides around pets.
