Not sure if you've already tried this vet or not, but his name is Dr. Brauer and he works at Dayton South Vet Clinic. Phone is 937-294-8888. When I thought I had red bugs, I spoke to him on the phone and he was very knowledgeable about them and treating them with interceptor. I ended up not having red bugs, so I didn't need the interceptor, so I'm not sure if he will charge you for an office visit or not.
