There are several different species of ants. Many can be annoying and can come into the home and not cause structural damage. These are easily treated and usually out of the house the day of treatment. Carpenter ants on the other hand are considered a Wood Destroying Insect. Therfore a Report is needed if you are selling a house. I can put a barrier on your structure to keep carpenter ants out guaranteed. Also, I can do a Wood Destroying Insect Report also called a NPMA-33. If your report comes back active I can treat for these Wood Destroying Insects.
