@Brian44, Sorry to hear about that. I know how bummer that can be for you and the guests. Living here in the South we can have roaches visiting inside our homes all the time. I was having the same issues before I listed my house on ABB. I tried a few things but I don't it really worked. Luckily my 3rd guests saw one dead cockroach the day they checked-out. Instead of calling the pest exterminator I decide to tackle the issues more seriously myself. After talking to some local professional exterminators and doing some researched online there are 3 products (see photos below - from Amazon) that sucessfully helped clear out my roach problem. After treating my house inside and out with these products, within 3 days I haven't seen any roaches nor bugs. I'm impressed that it worked so well and I saved hundreds of dollars. Anyway, I thought I share this info with you as you may want to pest treat your home yourself and save some $$. Also instructions on how to used these products properly are available on YouTube. Good luck!
