Is DEET (N,N-Diethyl-meta-toluamide) safe for dogs and cats?
Low risk for petsDEET products formulated for humans should not be applied directly to dogs, but incidental exposure is low risk.
What is deet (n,n-diethyl-meta-toluamide)?
DEET (N,N-Diethyl-meta-toluamide) is a insect repellent, amide, aromatic compound.

Risk for dogs
Low riskDEET products formulated for humans should not be applied directly to dogs, but incidental exposure is low risk.
Veterinary toxicology references indicate DEET has moderate toxicity in dogs if ingested in large amounts. Incidental dermal exposure is generally well-tolerated. Dedicated veterinary insect repellent products are preferred for dogs.
Risk for cats
Context-dependentGenerally considered safer for cats than permethrin, but not recommended for direct application. Cats may be more sensitive due to glucuronidation deficiency.
While DEET is not in the same high-toxicity category as permethrin for cats, felines have reduced hepatic glucuronidation capacity. Veterinary-approved products should be used instead of human DEET products.
Regulatory consensus
4 regulatory and scientific bodies have classified DEET (N,N-Diethyl-meta-toluamide). The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| US EPA | 2014 | Registered pesticide (active ingredient in insect repellents) | Re-registered 2014; considered safe when used as directed |
| WHO | — | Recommended for malaria prevention | WHO recommends DEET-based repellents for personal protection against vector-borne diseases |
| CDC | — | Recommended insect repellent | CDC recommends DEET along with picaridin, IR3535, and OLE as effective repellents |
| EU BPR | — | Approved biocidal active substance (PT19 — Repellents and attractants) | Approved under EU Biocidal Products Regulation |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
