I am getting eaten alive by something in my house that seems to be located in my bedroom or bathroom. At first I thought it was mosquitos because of the size and shape of the bites. I have been seeing the insects in the attached pictures in my bathroom sink around the drain and also on the tiled bathroom floor near the toilet and shower. The insects are about the size of a grain of fine-ground pepper and they might be mistaken for a fleck of dirt if they didn't move. Any ideas what these little beasties are, what is attracting them, and how I might be able to get rid of them? Also, they don't seem to fly, but they do jump. Could they be the source of the bites that are driving me mad? Any help or guidance you might be able to provide would be greatly appreciated! Thank you!
These insects are called springtails.
They do not bite.
Here is a page about them: http://extension.umd.edu/hgic/springtails
You may need to dehumidify the area.
Here too is a publication that can help drill down what it may be that is biting you or irritating your skin:
