Borax-based ant baits are attractive to ants because they contain sweet or protein-based ingredients that pets may also find appealing. Dogs and cats can be exposed by licking spilled liquid bait, chewing on bait stations, or eating granules tracked onto floors. Because the amount of borax varies by product and because pets can ingest a large quantity relative to their body size, all exposures should be treated as potentially serious.
Short-term effects of borax ingestion include vomiting, diarrhea, drooling, and stomach irritation. Larger ingestions can progress to lethargy, tremors, and kidney damage. Cats are generally more sensitive to borates than dogs, so even small amounts warrant prompt veterinary guidance.
To reduce risk, place ant baits only in locations your pets cannot reach, such as inside locked bait stations or behind appliances. Clean up any spills immediately, and check that outdoor granules are not spread where pets walk or graze. If you have pets, consider using physical barriers, cleaning up food residues, and choosing pet-safe or non-toxic ant control methods first.
If you suspect your pet has eaten any borax ant bait, contact your veterinarian or a pet poison helpline right away. Bring the product container and, if possible, note the active ingredient and estimated amount consumed.
