Best Ant Killer

By the nature of their hive system, ants are foragers. They need to invade space to find food that supplies the colony, and ultimately, the queen. They will march far and wide to find sustenance, and if that means invading your house or home, so much the better. They will gladly steal the crumbs on your countertops and kitchen floor, then they will leave a scent trail so that more of the hive workers can zero in on this new food source. You can spot kill the invading ants, but until you eliminate the colony and the queen, the ants will keep coming back.

The best ant killers on this list will target, not only the ants themselves, but the queen and the entire hive population. They will be easy to use, effective and give long lasting results. The one that makes it to the top will eliminate the entire hive for a terminal solution to your ant problems. And remember, always be careful around kids and pets when using any of the substances on this list.
