A1. Break off each of the four spurs to expose the holes, which allow ants access to the bait inside the station. One station is normally sufficient to eliminate one nest. Ants entering a building in different places may mean there is more than one nest. Check the station regularly (bait should be visible through the holes) and replace used ones. Keep the station dry whilst in use. If using outside, place the station near the nest and cover with a tile or brick to keep it dry. Leave alone, the ants will get used to it and it will eventually kill them off.
