dont freak out yet, these mites may not be as bad as you may think. these white mites are decomposers, they do not care about blood. I had these in my worm bin and I didnt mind them until they started to overpopulate.
black and red mites are the kind you need to freak out about.
Use a melon rind or something watery. they will swarm around it and then you toss it away. no matter how much you clean, disinfect, and sterlize your area they still find their way back.
