Arachnids have an exoskeleton – This term means that a spider’s skeleton is on the outside of its body instead of the inside.

While they can help control the insect population in your home, they can also reproduce at an alarming rate. The best move is to rid your home of both the spiders and the other insects they are feeding on.
