TERRO Ant Killer, the original ant killer, attracts and kills all common household ants including Argentine ants, ghost ants, cornfield ants, pavement ants, acrobat ants, white footed ants, little black ants, odorous house ants and other sweet eating ants.
The ant killer is specifically designed – using the active ingredient Borax- to provide fast-acting elimination of the queen and entire colony.
TERRO Ant Killer is a bait product, so at first ants will come in large numbers, but they will soon disappear. The product is specifically formulated to allow worker ants to consume the product and survive long enough to carry the liquid back to the nest and deliver a dose to the rest of the colony - including the queen.
Leave the product undisturbed while the ants are actively feeding on it and be sure to eliminate all other food sources in the area. This will ensure that the ants aren't tempted to eat anything but the deadly liquid ant killer.
This is the only way to get rid of both the ants you see and the thousands you don't! While the active ingredient in the bait will ultimately kill the worker ant, it interferes with the ant's digestive system and works slowly enough that the worker has time to get back and share the ant bait with the rest of the colony, including the queen. This slow kill is needed to allow time for the foraging ants to make several trips to the bait and deliver enough bait to the rest of the colony.
Tear the PLACE TERRO HERE cardboard squares from the ant killer packaging along the perforated lines and simply apply the product directly from the bottle onto the square. Small pieces of paper, cardboard, or foil also may be substituted.
The key to effectively eliminating the ant infestation is to monitor the placements and ensure there is always a fresh supply of TERRO Ant Killer for the ants to feast on. Depending on the size of the ant invasion, complete control may take up to two weeks.
Place the product where ants are seen, such as the edges of sinks, tubs, window sills, under food cabinets, along floors and baseboards and in corners. Do not skimp on bait placements; the more bait placements, the better.
Resist the temptation to interfere when the ants come in droves — your patience will pay off as you watch your ant infestation dwindle then disappear.
Since invading ants usually have outdoor nesting sites, it often helps to put the product outside, close to where ants are found entering the structure. Ants typically follow defined trails from the nest to food or water so placing the ant killer close to these trails will improve control.
Q: I just placed several squares of TERRO Ant Killer in my kitchen and it's attracting more ants, not killing them! What's going on?
A: You have nothing to worry about! Initially, you will see more ants. As ant foragers look for food, they are attracted to the sweet liquid in the bait which they consume and carry back to feed to the rest of the colony and the queen. On the way back to the nest, the ants drop what it called a 'trail pheromone', letting the other ants know where the tasty food supply is. In turn, these ants follow the trail to the bait which explains why you initially see more ants
Q: I've been using TERRO; Ant Killer for the past few days. When should I remove the bait stations?
A: We recommend leaving the bait out for three to four days after signs of ant activity diminish. If no more ants appear, remove the bait, relax and enjoy being ant-free!
Q: The ants in my kitchen are avoiding the TERRO Ant Killer – can you explain why?
A: As long as the bait is in liquid form (has not hardened or thickened) it should be effective because the active ingredient does not diminish over time. The ants may have found another food source, by seeking a grease-based vs. sugar-based food, or be in the breeding cycle of their colony and not interested in eating.
Q: How long does it take to eliminate an ant colony with TERRO Ant Killer?
A: The ants consume large quantities of the bait and then return to the nest and share it with the rest of the colony, including the queen, eventually eliminating the entire colony. This process can take from just a couple days to several weeks, depending on the size of the colony. Each ant that consumes the bait will die within 24 - 48 hours. It is important to leave the bait as undisturbed as possible while the ants are actively feeding on it. You should replace it only if it becomes inaccessible to the ants, or empty.
