felecia187 yes i know a lot about allergies lived with them all my life , so if you are an allergy suffer like me , listen up , lets say you suffer from seasonal allergies , which means you only suffer in the summer time , spring and fall , but now you suffer in the winter time and you don't know why , do you itch , when you are trying to sleep , do you feel some thing biting you at night but can't find the bug , well dust mites are really really small , do you have a carpet in your home that you lay on and get itchy , these are signs that you have DUST MITES now do not panic , there is a solution , wash all your laundry in water that is hotter then 150 c then vacuum your rug twice a week or more , or better yet get hard wood floors , get an air cleaner for your bedroom that has an ultra violet light because these type of lights kill dust mites , so this will help you to enjoy life free from these dust mites , and you will feel lots better with out your allergy's controlling your life , enjoy .
