How do I know when it’s time to switch to long-term ant killer?
Ant sprays are great short-term solutions to small ant problems. For example, you see a few ants on your counter, but there doesn’t seem to be a trail or a larger group somewhere in your house. An ant spray will do the trick to kill those worker ants, and your problem is solved.
The problem arises when you start to see ants every day, and no matter how many times you spray them, more come back. Soon you may start to see their numbers grow, or you may notice trails of them coming from a crack in the wall or a crevice near your back door.
At this point, you may have a larger problem at hand.
If you weren’t able to catch the small problem while it was still small, you might have to heighten your efforts. One thing you can try is switching from a spray to bait. Bait will attract more ants at first, but you have to let that happen in order to kill the rest of the colony.
