A: I have noticed small piles of dirt next to my exterior door threshold plate and some ants. On occasion I see what appears to be the same type of ant feeding on my pet’s food indoors. What type of ant could this be?

They often displace soil near their nest sites and have obvious foraging trails to food sources both indoors and outdoors. The big-headed ant also creates piles of dirt near expansion joints and cracks both indoors and outdoors. A trained pest control professional can easily distinguish between these two ants
