TERRO PCO Liquid Ant Killer Bait Stations (item# T300-NT) are now available with a new easy snap-off tab, making it quicker and more convenient to open each station for use. Prior to this new feature, a pair of scissors were required to cut and open the station. In addition, the station will now always be opened properly. TERRO PCO Liquid Ant Bait Stations are pre-filled with a 5.4 percent boric acid liquid bait, ideal for the control of sweet-eating ants. Packaged 30 per box, the stations attract ants fast, can be placed indoors or outdoors, and have no unpleasant odors, the company says.
