Is Terro Liquid Ant Bait Stations (T360) Safe for Pets?

Use with caution
Terro's Liquid Ant Bait Stations (T360) are use-with-caution, and they're an important verification within this cluster: this is not a single-borax product like the T300 — it's a dual-active "Ant & Roach" station combining borax (5.40%) with abamectin B1 (0.05%), a distinct roach/silverfish active.The borax portion carries the same comparatively low-toxicity profile as Terro's other ant baits, but abamectin is a more potent mammalian neurotoxicant with a documented breed-sensitivity issue — dogs with the MDR1 gene mutation, common in Collies and Australian Shepherds, can react severely to avermectins. Keep every station somewhere no pet can tip, chew, or crush it, and herding-breed households should be especially strict about placement.

The verdict for pet owners

The short, honest answer

Pet-safety score
50out of 100
Use with caution

The score rolls up every per-species verdict below, weighted by the honest exposure that matters — a chewed-open tube, not a hidden dab — and is checked against the EPA label and veterinary toxicology.

The verdict
Use with caution

A dual-active ant-and-roach station — the added abamectin means more caution than a single-borax bait, especially in herding-breed homes.

Terro's T360 is a genuinely different product from Terro's T300 despite the shared "liquid ant bait" branding: independent verification confirms it's a combination "Ant & Roach" station with borax (5.40%) in the liquid ant portion plus abamectin B1 (0.05%) in a separate roach/silverfish paste, EPA Reg. No. 149-21. The borax liquid mirrors the T300's comparatively low-toxicity profile, but abamectin is more toxic to mammals than borax and carries a specific, well-documented breed-sensitivity issue: dogs with the MDR1/ABCB1 gene mutation common in herding breeds (Collies, Australian Shepherds, and related breeds) can react much more severely to avermectins. A chewed-open station exposes both actives — station security matters even more here than with a single-active liquid bait.

Borax causes GI upset — the abamectin paste is the bigger concern, especially for herding breeds

The borax liquid gives typical GI upset at small intake, similar to Terro's other borax products, but the abamectin paste is the greater concern — especially for herding breeds (Collies, Australian Shepherds, and related breeds) with MDR1/ABCB1 sensitivity to avermectins.

CatsCaution
Cats differ — added blood-disorder risk

Sweet liquid attracts cats — both borax and abamectin effects are possible if opened

The sweet liquid can attract cats the same way it does with Terro's other ant baits, but if a station is opened, both borax GI effects and abamectin neurotoxicity are possible exposures to watch for.

Small mammalsAvoid

Never let pet rodents or rabbits access this dual-active station

Small body size combined with two separate actives — borax and abamectin — means pet rodents and rabbits should never have any access to this product.

BirdsCaution

Keep inaccessible to cage-free birds

Ingestion is the route of concern for a bird investigating a station; keep every placement somewhere a cage-free bird cannot land near or peck at it.

FishAvoid

Never let bait or rinse water reach aquarium or pond water

Abamectin is highly toxic to fish and aquatic invertebrates — never dispose of this product near aquarium or pond water.

Sodium tetraborate decahydrate (borax)

Borax works as a stomach poison for ants and carries a comparatively low mammalian-toxicity profile at bait concentration — the same chemistry and dilution used in Terro's T300, mirrored in this station's liquid ant portion. It is a real toxin, not "pet-safe," and typical small ingestions cause self-limiting GI upset.

Abamectin B1

Abamectin is an avermectin — a more potent mammalian neurotoxicant than borax — used in this station's separate roach/silverfish paste. It carries a well-documented breed-sensitivity issue: dogs with the MDR1/ABCB1 gene mutation, common in Collies, Australian Shepherds, and related herding breeds, can experience much more severe reactions to avermectins than other dogs. It is also highly toxic to fish and aquatic invertebrates.

The actionable core

How to use it safely around pets

Treat the reservoir as the hazard, not the ants' tiny draw — and because this SKU carries two actives in one station, security matters even more than with a single-borax liquid bait.

Place stations only where pets cannot tip, chew, or crush them

Position elevated or in fully enclosed locations — behind appliances, inside cabinets, or wall-mounted holders — not on an open floor.

Watch out
Because this station can hold more bait than a single dab and carries two actives, apply an extra margin of caution to placement.

Do not break the station open

Use the station sealed and intact as designed; never pry it open or decant its contents.

Watch out
A broken-open station exposes both the borax liquid and the abamectin paste at once.

Inspect daily and replace damaged units immediately

Check that stations are intact and upright; replace any that are cracked or leaking without delay.

Watch out
A damaged station can leak either active onto a surface a pet contacts.

Herding-breed households should be especially strict

If a Collie, Australian Shepherd, or other MDR1-sensitive breed lives in the home, apply extra scrutiny to placement and consider a single-active alternative instead.

Watch out
MDR1-sensitive dogs can react more severely to abamectin exposure than other dogs.
The re-entry rule

There's no drying window with this station — the safeguard is reservoir security for both actives, checked continuously.

Not applicable in the spray sense; the station should remain pet-inaccessible for the full time it's deployed.

Because this is a dual-active station, a chewed-open unit is a larger and more complex exposure than a single-borax liquid bait — treat placement with extra care.

    Emergency
If your pet was exposed

Act now — call a vet or a pet-poison line

Do not induce vomiting unless told to

If your pet accessed an opened, cracked, or chewed station, act now — estimate how much bait is missing and bring the station or a photo of the label when you call. This page is general information, not veterinary advice — for a suspected exposure, contact your veterinarian or ASPCA Animal Poison Control (888-426-4435) right away.

What each situation calls for

  • Your pet licked a small amount from an intact station

    Typically low-concern, but monitor closely and call your vet or a poison hotline if any GI or neurological sign appears, given the dual-active nature of this product.

  • A station was found chewed open, cracked, or empty

    Treat as a genuine dual-exposure — note roughly how much bait is missing, then call your vet or ASPCA Animal Poison Control and mention that this station contains both borax and abamectin.

  • Your dog is a herding breed and may have been exposed

    Call your vet or a pet poison hotline promptly and mention any known MDR1 sensitivity — herding breeds can react more severely to abamectin and may need closer monitoring.

In the next 60 seconds

  1. Move your pet away from the station and any spilled bait.
  2. Estimate how much bait is missing from the station — mention that it contains both borax and abamectin.
  3. Do NOT induce vomiting unless a veterinarian or poison expert tells you to.
  4. Have the product name and EPA registration number (149-21) ready.
  5. Call your veterinarian or one of the hotlines below — mention any known MDR1 sensitivity if your dog is a herding breed.
Lower-risk options

Safer pet-friendly alternatives

Honest options that reduce or remove pet-toxicity — no affiliate hype, real caveats included.

Single-active borax liquid stations (if only ants are the target)

Safer

Alternative bait chemistry

If roaches or silverfish aren't the problem, a single-borax station like Terro's T300 avoids the added abamectin exposure entirely while still targeting ants.

Still requires the same out-of-reach placement and reservoir security — borax is not "harmless."

Exclusion and sanitation

Safer

Non-chemical

Removing food, water, and entry points reduces both ant and roach pressure with zero pet toxicity.

Slower than baiting for an established infestation; pairs well with securely placed bait.

Enclosed, tamper-resistant stations placed inaccessibly

Safer

Enclosed bait

Applies to any bait format — the biggest safety lever is a location no pet can tip, chew, or crush, regardless of which active is inside.

Still contains toxicants — verify integrity regularly.

Professional baiting matched to the actual pest (Anchor Pest Services)

Safer

Licensed professional service

A licensed applicator can choose a single-target product instead of a broader combination bait, and can factor herding-breed sensitivity into the plan.

A service, not a product — mention any MDR1-sensitive breeds in the home when requesting a plan.
