#1 Large Black Ants (with and without wings)
Carpenter ants don’t actually eat wood; they just destroy it to make a tunnel. What they feed on are the usual – something sweet, parts of dead animals & insects, and fruits & vegetables. Some of them are winged and some of them are not. If seeing winged ants are becoming more frequent, it’s a sign that they’re looking to spread their colony; as they have probably already used too much space in their nest.
#2 Wood Damage
As we’ve mentioned, carpenter ants can be really destructive if left alone. Once you start seeing these critters, check all your walls, nooks, and crannies for any change. If you’re structures have a smooth hole in it, then it’s most probably due to the carpenter ants excavating them.
#3 Sawdust Trail
With wood damage comes the trail. Piles of sawdust can be seen near walls and floors of the carpenter ants’ nest. Some piles of sawdust may even stick on your carpet, if ants normally go through them.
#4 Rustling Sound
In very heavy infestations (and if you put your ear against the wall), you may hear faint rustling sounds coming from the walls. The sounds actually come from the carpenter ants moving and chewing through the wood. It is where most likely they are building their nest.
The first step in dealing with an infestation is to know where they are. Due to their number and behavior, carpenter ants can be quite the challenge to evict from your home. Once you’ve found you have an infestation, call a trusted pest professional as soon as possible.
