Terro-1% Ant Bait Stations can be used indoors where ants are seen, including the edges of sinks, tubs, windowsills, under pallets, storage shelves, food cabinets, or appliances, along floors and baseboards and in corners and other area where ants may forage. Do not skimp on bait placements; the more bait placements the better. Using the stations outside, place around decks, loading docks, crawl spaces, fences, foundation perimeters, trees and other areas. Ants typically follow defined trails from the nest to food or water. Placing this product close to these trails will improve control.
