If you have a problem with bed bugs this article may help. Here are 24 natural ways to get rid of bed bugs. From alcohol to spices you will find ways to deal with them in every room of your house. Organic Pest Control NYC shares this info. I think if I had to deal with them I would use the Diatomaceous Earth (Food Grade). Bed bugs can live for months even without biting someone for the blood. You can see traces of them on mattresses.
If you are staying at a hotel and want to check for them peel back the sheet off the mattress and look in the creases on the edges of the mattress, if you see black and brown spots along that area then you know they are there. That is fecal stains from the bed bugs. If you see that I would not stay there. If you are fighting them at home and can not afford a new mattress I would buy one of those mattress covers that the mattress slides into and then it zips closed. I would put that on the mattress and before zipping throw a bunch of diatomaceous earth (food grade only) in there. The DE scratches the shells of bugs like glass and then they dry out and die.
