eek! Ok, so these "things" keep biting me and they itch! I have narrowed it down to dust mites, and the reason being is cause I have not dusted my room in like 6 months. I'm a college student so I don't have time to. These bites come and go. Sometimes there will be up to 5-7 bites and some only 2-3, they happen mostly on my arms and legs....(for now) the bites dont last more than an hour..Meaning they stop itching and you cant see them anymore. I have good hygiene and bathe every morning/night so i'm a pretty clean person...And these bites came out of nowhere. I never see anything nore do I even feel when they bite....Just itching then red/white welts...They also mostly only happen when i'm on my bed, i've washed my sheets and pillow cases like 50 times! ... I think they are microscopic (dust mites) but I do not know for sure. I'm so scared and dont want people getting them when they come to my room! Here are some pics...Both pics are of my left fore arm. Thanks for any replies!!!

by the way, these also look like when I get bit by a mosquito, but there are none here cause of the cold I think..But I do not see any mosquitos anywhere..
