DEET (N,N-diethyl-m-toluamide) is a widely used insect repellent that helps protect against mosquitoes, ticks, fleas, and flies. In Australia, products contain anywhere from lower concentrations (around 10%) to highly concentrated formulations (up to 80%) and are available as sprays, creams, gels, and lotions. These products are mainly intended for human use, although limited use exists in some animals such as cattle, dogs, horses, and pigs.
Pets are most commonly exposed by licking treated skin, chewing or knocking over containers, or being accidentally sprayed during application. Small exposures often cause drooling, vomiting, diarrhoea, or mild stomach upset. Larger amounts, or exposure to stronger products, can affect the nervous system and may cause wobbliness, disorientation, tremors, and in severe cases, seizures. If DEET gets into the eyes, it may cause redness, watering, squinting, pain, or irritation. If inhaled, it can irritate the airways and may lead to coughing or difficulty breathing.
The risk of poisoning depends on the route of exposure, product concentration, and amount involved. If your pet has been exposed to a DEET-containing product, you can contact the Animal Poisons Helpline for a rapid risk assessment, guidance on immediate first aid, whether veterinary treatment is required, or if home monitoring is appropriate.
