I Have a Question

Has anyone ever had issues with bedbugs and how did you deal with it? I've been having issues with them for a while and like a dummy ive been dealing with it on my own, I got pest repellers, ive used sprays and set traps, and got one of those mattress covers, nothing works, anyways, I finally realized maybe i should get some help with it, my neighbors have had issues too. I finally told the manager in my apt building about it, guess i was scared to bring it up, next wk the pest control guy is paying me a visit. not sure if hes going to spray or do the heat treatment, get the feeling he might use heat. i dont have to pay for it cause im in hud housing unless it happens again. just wondered if anyone has ever dealt with this and how?
