Question: What over the counter treatment can I buy to prevent and get rid of bugs?

ANSWER  Preventing bedbugs is mostly a matter of inspection(as opposed to buying chemicals).

When you go from one place to another, check your luggage.  Bedbugs are notorious hitch-hikers. They can crawl into a suitcase in one city and infest a home or apartment in another city.  They are easily transported in back packs, gym bags, and brief cases.
