From the most widely respected and well known ant killer comes the TERRO PreFilled Liquid Ant Killer II Baits. All TERRO products are good, but this one has everything else beat. It comes in a prepackaged liquid formula in bait stations, This means you don't have to handle the bait. Just place the station where there is known ant activity, and let it work. The active ingredient is borax, which is a slow kill and allows the ants to take the bait back to the colony. Once there, everyone eats this bounty, including the queen, and the colony is eliminated. Best of all, it is a sweetened liquid, so it is easy for the ants to consume, which makes it highly desirable, and that means they want more of it. TERRO liquid baits are the best, bar none!
TERRO PreFilled Liquid Ant Killer II Baits attract more ants because they are a liquid and easy to consume. That means more ants come to feed, which also means more ants take the active ingredient, borax, back to colony where everyone feasts on this bounty, and perishes.

Fire ant killer in bait form is best used as a preventive measure, as it is slow acting. It is a poison mixed with natural food sources that is carried back to the nest, eventually killing the queen ant. It is most effectively applied in the spring or fall, and should be spread in a wide area around the nest. Be very careful not to disturb the nest itself, or the ants will panic and very likely relocate. Using bait as a fire ant killer is really only effective on very small nests, or as a pre-treatment to areas prone to infestation.
