Ants are multi-queened, meaning that they have several queens who are working and laying eggs every day, so the colonies can grow in size very quickly. With using baits as our method of treatment, we are relying on the worker ants to take the bait underground and feed it to the other ants and multiple queens. Depending on the size of the colony, it may only take one treatment to gain control, but for larger more established colonies, it may require 1-2 follow-up treatments. We generally recommend ant follow-ups to be either 2 weeks or 1 month after the initial treatment. Our technician will make his follow-up recommendations based on the activity level that they see during their inspection.
