Mulch and termites
The termites that we have in Maryland are not attracted to mulch.
They are subterranian, living out of sight and moving within enclosed tubes.
You have many options for what your mulch is made of.

Stay away from the cocoa bean hulls, which are attractive to dogs and other animals but the theobromine in them is toxic.
