Due to the wonderful humid weather that we have here in Indiana, dust mites are a plenty! For the past couple of springs and summers we have had a lot of problems with this bugs on our bed. Every year we have to take the proper sets to lower their numbers and insure that we are not bitten up throughout the night. Well, last night was horrible. We have yet to take the steps in lower their numbers because I totally forgot about it. Yesterday was a horribly humid day though and last night they were out in force. I actually saw one crawling on my finger when I held it up to the light of the television. I am so tired of bugs. So now I get to look for a plastic or other type of sheet to keep the dust mites from crawling through and onto us as well as some spray to spray on the mattress and box. Nice. I love it.
