I was being attacked by something and constantly scratching itchy red spots on my body. Couldn’t work out what it was but after viewing pictures of bed bug bites decided this must be the problem. I never sighted one so wasn’t 100% sure. Meanwhile I felt considerable discomfort eased a little by using copious amounts of calamine lotion. After getting over the shock and horror of a probable infestation I came across Bed Bug Barrier then immediately ordered the Bed Bug Killer Powder and Bed Bug Duster. Followed the directions and BINGO immediate relief in that there were no more additional bites when I woke the following morning. The Bed Bug Duster is easy to use and ensures powder is distributed effectively with no unnecessary product wastage. I used it in the morning and was able to sleep in my bed that night. This really does work and I highly recommend the product and the company.
