Why Terro Liquid Ant Killer Bait Stations Is Necessary
Liquid ant bait is necessary because sprays only kill the ants you see, while the colony keeps sending more. A bait that ants carry back to the nest kills the queen and the whole colony, which is the only way to stop the problem for good. I have sprayed trails before and watched new ants appear the next day, and bait is what finally ended it.
Placement matters as much as the product, because bait only works if the ants find it and carry it home. I placed stations directly on the trails I could see, near entry points, and along the foundation outside. The baits that worked fastest were the ones placed exactly where the ants were already walking.
Patience is part of using bait, since the ants need time to carry it back and share it with the colony. The trails may look worse for a day or two as more ants show up to feed, and that is actually a good sign. The products in this guide all worked within a week when I placed them right and waited.
