google is your friend. especially the hits where the National Park Service deals with this. basically, you need to observe their entrance holes and spray poison into it. covering your bods as much as possible helps. burning is a NPS option though i was too chicken to try it myself. i had them lodged in a railroad tie retaining wall this year. i have to nuke all openings and then seal with expanding foam. looks ugly but over the course of a few weeks it did work. i didn't wear any gear beyond long pants but i did make sure to have a clear exit path back to my patio door!
