I have been getting bitten constantly all summer and now even after two light frosts. The culprits are not skin colored but white and look like dry skin or dandruff but when you try to brush off what appears to be dry skin you find that the thing is really stuck and the bite hurts and it is very hard to get it out or off. I have all kinds of scars from trying to get them out and itching. I began getting only bitten outside as I sat on my patio but now after three months. They are in my carpet and bed.
What are they and how do I kill them and also keep them off me? They go through layers of clothes even though the outer layer is sprayed with a spray for bedbugs (and other pests that contains Deltamethrin. What can I use to kill them and what can I use safely on myself and my dog?
