This work was completed at my fiance's home in Pittsburgh. The first time we contacted them was at the beginning of June, 2012. Somehow our Pittsburgh home had attacted bed bugs. For anyone who goes through this experience, it's horrific! ESPECIALLY when you're "garunteed" that the problem will be extinguished and it's not. We have had this company return to spray 6 times, total. 4 of these times, they required payment AGAIN... On a garunteed product, this seems a little backward to me. Either the product doesn't work or it's not being properly applied. All instructions given were followed to a T. We ended up having to use another company to eliminate the problem. 1 treatment, at the problem was gone! I do NOT recommend this company. Not only did they argue with my fiance' about the payment, but they acted like they were cutting us a deal and that it was OUR fault that the treatment wasn't working at all. Good things were that they did respond quickly. However the person that they sent every time needed a bath terribly and the smell of them was extremely unprofessional.
