Terro-1% 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.
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. For example: 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.
