Aside from seeing them with your own two eyes, there are a number of ways to find out if you have carpenter ants in your Minneapolis home. If you’re finding a buildup of sawdust-type wood shavings in unfinished areas like basements or attics and you haven’t been doing any woodworking, that’s a major sign that you have ants. Also, if you see a line of carpenter ants outside in close proximity to your home, there’s a chance they may also be inside your home. Sometimes you can even hear them at night – talk about creepy! If you discover carpenter ants in your home, it’ll typically be in an area with a high level of moisture because carpenter ants need that type of environment to construct their colony.
