You’ll see a large number of bedbug sites out there selling specialized mattress covers to keep bedbugs from getting inside your mattress (or outside, if you’re infested), but did you know that you can buy them right from your local store or better yet, eBay (and let the stores compete!).
It’s a lot less expensive and you need only ask the clerk to direct you to the mattress section and look for allergy relief / dust mite barrier covers; these are effective enough to stop bedbugs from passing through as long as it completely seals the mattress. Make sure there are no gaps where the bed bug could crawl out or in, often found near the zipper.
On this bed bug mattress covers page I list manufacturers competing with each other on eBay by offering extremely low prices; however, go to a store specializing in these covers where competition doesn’t exist and you can expect to twice what you would otherwise pay!
It’s always disturbing to find that you payed far more than you should have for a product, so take your time, compare prices and make sure that you’re getting an inexpensive bedbug cover that will do the job right the first time!
