I do recommend that. I have been dealing with someone who has been out once and he helped me figure out the problem the first time. They just created a new one. He’s coming back tomorrow if I don’t figure it out sooner.

We know they’re in the ductwork and the crawl space - we need the point of ingress blocked. We already need to repair/replace the ductwork and do other work in the crawlspace - having a pest control person out to look would be easy enough.
