Refillable ant traps for quick & convenient elimination of ants & their nests without trace. At the first signs of ant activity (normally early spring). How to Use: Remove readily available foodstuffs. Pierce four holes in the sides of the ant trap where indicated. Place a few drops of the liquid in the centre of the trap & replace the lid Place the trap as close to the ants nest as possible (do not disturb feeding ants as it is essential that feeder ants take the bait back to the nest to the rest of the colony). An effective dose is usually built-up within the colony over 7-10 days, depending on the size of the ant colony & the frequency of ant feeding.
