The TERRO Outdoor Ant Killer Spray takes care of more than just ants. Kill ants, (including carpenter ants), spiders, boxelder bugs, cockroaches and more with this versatile spray. Spray pests from up to 15 ft away so you have no need to get too close! To use the spray, simply apply to cracks and crevices, reaching deep within to reach where ants and spiders like to hide. This spray can also be used along ant trails that, if followed, will lead to the anthill where more ants live. To protect your house or business, spray along the perimeter of the building as a barrier for insect pests.
