This Home Defence Ant Stop Bait Station aids in keeping your home immaculate and insect-free. These ready-to-use traps are ideally designed to kill ants and their nests specifically. The ants are attracted to the designed bait and carry it back to their nests. The formula is devised in a way not to kill the ants immediately but their root of infestation. Instructions: The stations can be used in and around the home. The enclosed design means they are clean and simple to use. Place the station where you see ants run, if you see ants entering your home in different places remember that there may be more than one nest in the vicinity. Warning: Always read the label and product information before use. Contains Fipronil.
