Is Ant Baits & Traps (Borax / Avermectin) Safe for Dogs?
Why it’s a problem
Bait stations hold tiny amounts of borax or avermectin diluted in a sweet attractant, so a dog would need to eat many traps to reach a dangerous dose. Most exposures cause only vomiting or diarrhea. The real danger is the plastic housing, which can be chewed into sharp pieces or swallowed whole and cause an intestinal blockage.
How to keep your pet safe
Place traps inside secured stations or behind appliances where your dog cannot reach, and collect loose ones after treatment ends. If your dog treats traps as toys, switch to sealed gel baits applied in cracks. Check garages and patios before letting your dog roam.
Warning signs to watch for
Drooling, vomiting, diarrhea, loss of appetite, mild lethargy, abdominal discomfort; possible gagging or constipation if plastic pieces were swallowed.
When to call the vet
Call your vet or a pet poison hotline for advice — most cases need only monitoring. Watch for repeated vomiting, a swollen belly or failure to pass stool, which can mean the plastic is stuck. Never try to make your dog vomit up plastic pieces yourself.
Common questions
My dog ate an ant trap — should I panic?
No, panic is not needed — the poison inside is diluted and rarely dangerous in one trap. Do call your vet or a pet poison hotline, and watch for signs that plastic pieces caused a blockage.
Are Terro-type liquid baits dangerous for dogs?
They contain borax in a very dilute sweet solution, so a single station usually causes only drooling or mild vomiting. Confirm the ingredients with a pet poison hotline, and keep the rest out of reach.
What if my dog only chewed the plastic trap?
Watch for choking, repeated vomiting or constipation over the next 2–3 days, which can mean a swallowed piece is stuck. Call your vet if any of these appear or if a whole trap is missing.
