Some people would rather try to do it themselves with Bed Bug Bombs, Sprays that say they work, alcohol that kills only on contact, and yes renting Heat Treatment Equipment. Let’s step through some of this. Chemicals that are available over the counter only have to kill a Bed Bug so long as it kills in an ideal environment. This would be like a glass bowl that 100% of the product is on the surface unlike Couches and Beds that soak up 80% of the Chemical. Also the Bug cannot get away. If the Bug can get away from a product that that it can detect it will and just about all the over the counter products are detectable by Bed Bugs and take long exposure times to kill them with 100% of the product on surface.
