Wow, bedbugs are one of the hardest pests I have ever had to deal with. All the washing and cleaning made little difference, and pesticides- not effective. I contacted bedbudbarrier.com.au and got the powder, and other products but most importantly the education from the site. Armed with all of it I finally started to make progress. I made an electronic enquiry which was returned by a phone call. Great company to deal with, and fairly price. Thanks for helping me get my sanity back to my sleep time.
