Terro PCO Liquid Ant Bait, manufactured by Nisus, is an effective liquid borate base bait that instantly attracts and kills all common household ants like carpenter or little black ants and their colonies with one convenient application.

This liquid ant bait offers slow control over indoor and outdoor ants to allow the foraging ants to bring back the bait to their queen, effectively killing all present and future ants. It contains no odors and once ingested by the ant it kills them by disrupting their digestive systems.

Terro PCO Liquid Ant Bait contains a higher percentage of the active ingredient Sodium Tertaborate Decahydrate 5.40% then other ants bait using this active ingredient. Another benefit of the active ingredient is that it is considered a natural ingredient with a low toxicity to people, but lethal to ants.

Special Considerations

As a effective ant bait killer, ants will first come in large numbers, but soon disappear. Terro PCO Liquid Ant Bait 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. The key to obtaining effective control is to monitor the placements and ensure there is always a fresh supply of Terro PCO Liquid Ant Bait on each placement. Complete control may take up to two weeks.
