Dear Help,
We believe you probably need a true specialist for this identification, but we are leaning toward the Tropical Rat Mite, Ornithonyssus bacoti. We first located an image on BugGuide, but it is very tiny. Then we found a wonderful informative website on Biting Mites in Homes. The website states: ”
Rat and bird mite infestations occur in structures where rat or bird nests are located. Infestations are sometimes first noticed following extermination, or after the natural hosts have died or left the structure. Infestations may also occur where heavy mite infestations have developed around a rodent or bird nest. Rat mites are small, approximately the size of the period at the end of this sentence. They move actively and can be picked up with a wet finger, brush or piece of sticky tape. Distinguishing between different species of Ornithonyssus mites to determine whether birds or rodents are the likely source is difficult and requires special expertise. The best first course of action, when faced with biting mite problem is to look for all potential bird or rodent sources.”

It could also be the tropical fowl mite or bird mite (Ornithonyssus bursa). For information check out: Good luck.

  1. Do you own a hamster? or other small animal? I went through a terrible time trying to figure out what was biting me and they bite at night! It was a tropical rat mite diagnosed by the University of Florida. This mite needs to be killed on the animal who is the carrier. I can tell you it reproduces from a larvae, every 7 days so getting treatment for the animal is key my vet gave me drops for the hamster to take weekly this took over 6 months! I wll never buy another small animal before having a vet check.

  2. When I open my car looks like white cotton comes out then they bite me.ture into black dots like fleas I had rats in my garage and bird in my dyerand I see little sinew things on my rug.
