My son bought bed bugs back from his Fiji schoolies trip. I tried a product from Bunnings but the bed bugs were back pretty quickly. So, with diligence, I bought the powder and the mattress covers for our mattresses. Following the directions, against the advice of others who said “only use a professional”, I spent a day going through the motions. Success!! No bed bugs and it has been more than one year later. Thank you Bed Barrier, it is possible to get rid of bed bugs and got cost a fortune.
