As a backpacker hostel bed bug prevention is a top priority! Previously we used a chemical spray for our annual prevention program. We had a couple of outbreaks and it appeared that the treatment was no longer working as effectively. Our pest control guy studied bed bug barrier & we decided to give it a go. He uses the powder on the mattress (which is then covered by a mattress protector), powder in any nooks and crannies we can find together with the floor and screw-in barriers. It has been 18 months since our first use. He has just undertaken the annual inspection of all rooms and found virtually no trace of activity (except a few dead bodies that came in alive and died at the scene!) which is pretty amazing considering the nature of our business. Together with bed bug barrier and our pest control expert – we are so happy to report an effective solution with the peace of mind that comes with the product being non-chemical.
