Designed for indoor use, it’s easy to apply on cardboard tiles placed near ant trails and entry points. Fast-acting and trusted by millions, TERRO delivers precise, colony-wide control in a compact 1 oz bottle. ## Description Product Description Attract and kill the ants you see, as well as the ants you don’t see with TERRO Liquid Ant Killer. The liquid, which contains borax, is specifically designed to allow worker ants to consume the product, survive long enough to carry the liquid back to the nest. Ants consume the liquid ant bait and return to the nest where they pass it around to the rest of the colony. The active ingredient in the bait slowly interferes with the ants’ digestive systems, ultimately killing them. Since this is a bait product, you will initially see more ants as they are attracted to the liquid – but don’t worry, this is a good thing. After the bait is consumed, insect populations will begin to decline. Complete control may take up to two weeks. The 1 oz bottle offers plenty of ant-killing power to eliminate your infestation. For your convenience, TERRO Liquid Ant Killer is easy to use. Simply apply drops of the liquid ant killer directly from the bottle onto the smooth side of the cardboard tiles included on the packaging. Then place indoors on a flat surface near ant trails and other signs of ant activity. The more bait placements, the better. Be sure to leave the ant killer undisturbed while the ants are actively feeding on it.

Haven't had this bottle more than a year or two and yesterday they ignored it like the plague.** A: Once the clear liquid changes into a light yellow color it becomes less attractive to the ants and if dark brown they avoid it like poison. I've tried to re-dilute it a little with purified water with some success, but as soon as I switch in a fresh bottle, the same ants that ignored the old stuff start eating the bait like crack. So yes.. there is an effective shelf-life of 6 months to a year once opened, the better re-sealed it is after each use, the longer the shelf life. **Q: Does Terro Bait work against argetine ants? Any success story to share?** A: from the manufacturer website: The most reliable way to eliminate an entire colony of Argentine ants is to use liquid ant baits. TERRO® liquid ant bait products provide fast-acting elimination of the colony. Once foraging worker ants find the ant bait, they will go back and share it with the rest of the nest. TERRO® offers ready-to-use indoor and outdoor versions of Liquid Ant Killer Baits. **Q: how long does it take to see less or no ants?** A: This product will kill the ants that consume it within 24-48 hours. Depending on the size of the colony, it may take several weeks to notice a decrease in ant activity. **Q: Is it pet friendly.** A: The active ingredient found in TERRO® liquid ant bait is a Borax. Borax has a low toxicity for people and animals, but ants are another story. When ants consume the Borax bait, it interferes with their digestive system and gradually kills them. This slow kill allows time for the worker ants to consume the bait and head back to the nest to share with the rest of the colony.But, as with any pesticide, it's important to read the included instructions for information on how to best store and apply the product around children and pets. ## Frequently Bought Together - Terro T100-12 Liquid Ant Killer II, 1 oz, Pack of 1 - TERRO Ant Killer Bait Stations T300B - Liquid Bait to Eliminate Ants - 12 Count Stations for Effective Indoor Ant Control - TERRO T901-6 Ant Killer Plus Multi-Purpose Insect Control for Outdoors - Kills Fire Ants, Fleas, Cockroaches, and Other Crawling Insects - 3lb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1401196-terro-1-oz-liquid-ant-killer-attract-and-kill-household](https://www.desertcart.pt/products/1401196-terro-1-oz-liquid-ant-killer-attract-and-kill-household) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-13*
