Scared- Think I saw a BED BUG in my hotel?

Okay take a deep breath and calm down, I had bed bugs and I must have had them for a while because there were hundreds under my bed around the edges. I haven't had a problem in a month with what i used its really cheap and easy to use. Rubbing alcohol. I swear this is what I used this kills them but only on contact. They die in extreme heat or cold so your suit cases and stuff should be fine, all you have to do is throw your clothes in the dryer for 20 minutes on high heat. Literally they were in my clothes and as i pulled them from the dryer those things fell dead on the floor. Vacuum vacuum vacume!!! they can be on you. So just vacuum. Seriously I promise no problems in a month
