Ants aren’t good neighbours, they’re unfriendly pests. Stop invasive ants with Ant Killer Dust. This ready-to-use product is intended for general use, but is especially good for cracks and crevices wherever you may find them, indoors or outdoors. Applying it around the perimeter of your home will create a barrier that ants will have to try and crawl through, thus initiating contact and killing them within 48 hours. Another ant bites the Dust! That’s the idea.
