We live close to several farmer's fields and have gotten overwhelmed by some type of grain mite. As of yet, no one has been able to identify which specific type. Have tried many different sprays along w/ the exterminators advice. Anyone know how to get rid of these things. We have lost a couch and recliner along w/ our mattresses and window coverings because they live off the cotton, etc... This has cost us several thousand dollars and it's almost the time of year that this began last year. We need any advice you can offer. Thanks!
