As a general rule repellant liquid treatments kill mostly the workers and foragers, but not the reproductives or the larvae, inside the ant colony. When using baits, the foragers bring the bait into the colony to be given to all as nourishment. It can take a few weeks for there to be a noticeable decrease in ant sightings when using only baits. But in the long run it can be the most effective path to elimination.
Some species of ants can be a real challenge to deal with. Here in the Raleigh/Durham/Chapel Hill Triangle it is the odorous house ants that give us the most difficulty. They are commonly found in kitchens and bathrooms and can sometimes be seen trailing up the exterior foundation walls of your house. Because these ants can have numerous small colonies, it makes it almost impossible in some cases to find them all. A combination of a non-repellent liquid treatment around the exterior foundation and placement of baits in their foraging areas seem to work best for this type of ant. In most cases it will be a minimum of two weeks, if not longer, for complete control.
Fire ants are another persistent and challenging species of ant here in the Triangle area. There are many types of bait available that work great on fire ants. A non-repellent liquid treatment can sometimes be effective on a minor infestation of two or three mounds, but you may want to call in the professionals once they become more numerous. Innovative Pest Solutions offers a one-year guarantee on their fire ant treatments. We hope this post on Ants: Bait vs. Liquid helps our readers.
