First off you should ALWAYS go to pest control if you think you have bedbugs! You shouldn’t try and get rid of them yourself, 99% of the time it does not work. Plus even if you removed infected areas and wash them it wouldn’t kill the eggs. Plus bedbugs are very easy to get but very hard to get rid of. So you should never do it yourself it won’t work!
When professionals need to treat an infestation, they don’t reach for rubbing alcohol or cedar oil or a blow dryer. They use a proven treatment process that involves a combination of proven products to get the job done. It’s not about whether or not a certain item can kill bed bugs, it’s about whether that item is the ideal part of a treatment that will actually get rid of an infestation. After all, your shoe would have a 100% kill rate on any bed bugs you smack with it – that doesn’t mean you can expect to be bed bug free after a diligent afternoon of shoe-wielding.
