I had an infestation of bed bugs this past summer.
Armand and team treated my house. (Side note: it's brutally hot afterwards for 2 days, find somewhere else to sleep).
About three weeks later I woke up with more bites on my neck. I called Armand and he came in and treated my room again. Apparently the wall was super thick and some bugs were living in there. His partner told me I must have brought them back in from work - impossible, as I undressed in the garage every day! I treated my office anyway since I needed the peace of mind. Armand gave me a good price and was very kind.
Overall I was happy with their service. It sucks that my room had to be treated twice but that's the bugs fault I guess. I would use them again.
