How DEET harms pets

DEET blocks nerve signals that control sensation and movement.

Pets lick it off their fur or chew the bottle.

Even small amounts can cause rapid onset of symptoms.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Symptoms of deet-insect-repellent poisoning

  • Vomiting and diarrhoea within 1–3 hours of ingestion.
  • Excessive drooling and pawing at the mouth.
  • Tremors or muscle twitching that start 2–6 hours later.
  • Difficulty walking or staggering by the evening.
  • Seizures in severe cases, usually within 12 hours.

What to do right now

  1. Call your vet or a poison line immediately; bring the product label.
  2. Do not induce vomiting unless instructed by a professional.
  3. If DEET is on the fur, gently wash it off with mild soap and lukewarm water.
  4. Watch for neurological signs like tremors or stumbling for at least 24 hours.
  5. Keep all insect repellent products out of reach, especially spray cans.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
