Ants have always been an issue on Nantucket. Even the cleanest house can have ants. All it takes is a few crumbs and the smallest opening for foraging ants to get in. Ants leave a trail for there friends to follow. If you got one you most likely will have a whole lot more pretty quickly. We recommend every one have there foundation treated 2-3 times per year as part of a maintenance program. In addition you may want to add an indoor insect treatment to your maintenance program.
