I was lying on my bed on the top of the covers for 20 minutes and felt an itch on my back. I scratche it several times and when I got up I looked in the miror and saw three bites. I found a few small black bugs(smaller than a pin head). What can they be? With a magnifing glass they look like tiny beetles or spider mites. What can they be and where do they come from? How do I get rid of them? Thank you.

I would put them in a bag take to the health department/pest control for identification... lately on the news there has been a lot of places infected with bed bugs.

Got any Oak trees around your yard. This could be Itch Mites that fall from oak trees. Itch Mites Linked to Oak Trees Plaguing Midwesterners Again 10/18/05

Ask your mum or dad or any friend of yours to pick them and throw them in the bin. Or spray anti kill insect spray on your back. They don't harm your skin so don't worry

I am sure you meant the opposite of anti kill, you do want to kill them, right. Itch mites can cause a welt up to 1/2" wide and itch like crazy. Scratching can cause a secondary infection too. They really do harm your skin in fact.

Yes yes I meant kill kill kill
