TERRO® Liquid Ant Killer

Ants can be a problem anywhere – in the home, at work and everywhere in between. To kill common household ants, place TERRO® Liquid Ant Killer in areas where you've seen ant activity. This will attract foraging ants so they can take the bait back to the nest. As the bait circulates through the colony, it kills the ants you see and the ones you don’t. Within a few days, you should see a significant decrease in the number of ants visiting the bait.

How it works

How It Works

Since this is a bait, initially you will see more ants – but don’t worry, this is a good thing. Why? As ants forage for food, they are quickly attracted to the sweet, sugary liquid. After finding the bait, worker ants consume it and leave behind a pheromone trail leading back to the colony. This trail lets other worker ants know where the newly discovered food supply is. This is why you will see more ants in the beginning.

Meanwhile, the active ingredient, Borax, is slowly interfering with the ant’s digestive system, ultimately killing it, but leaving enough time for the ant to go back and share the dose with the rest of the colony. This slow kill is necessary so that foraging ants can make several trips to the bait. The communal nature of an ant colony allows the bait to be spread to hundreds, if not thousands, of individual ants.

Where to Place

Place TERRO® Liquid Ant Killer near ant trails and other locations where they are numerous. Apply the baited cardboard tiles on the edges of sinks, tubs, windowsills, under food cabinets, along floors and baseboards and in corners. Each of the 1 mL droppers is just the right amount for a single bait placement.

How to Use

How to Use

TERRO® Liquid Ant Killer is very easy to use. Before placing the ant killer, be sure to remove other sources of food, such as crumbs, sugar, and grease spots to prevent attracting them elsewhere.

  1. Simply apply drops of the liquid ant killer directly from the dropper onto the smooth side of the cardboard tiles included on the packaging.
  2. Place tiles indoors on a flat surface near ant trails and other signs of ant activity.
  3. Be sure to leave the ant killer undisturbed while the ants are actively feeding on it.
