Entomology (Study of Bugs)/Tiny black bugs that sting
For two months now we have been dealing with tiny black bugs invisible to the naked eye. We finally caught some in a glue trap. They are so tiny that to really see them I had to use a magnifying glass. They have two antennae a head and a thin body and wings. We had a few that were a little larger that we submitted to Teeminix and they could not identify them. We are getting ,what I would call, stung by these insects. It's a very sharp pinch then it goes away. Terminix came in and said we had fleas and sprayed but we had no flea bites and have no pets. I live in western Pennsylvania and have searched the Internet for this bug. One exterminator said it was a flying ant but told me they wouldn't bite. We are stung under clothing and on exposed skin. Please help! I have a son and am worried about pesticides.
There are no insects that exactly fit your description. Here's a list of insects and mites that do bite people and some things that can be mistaken for bug bites http://www.livingwithbugs.com/unknown_bug_bites.html
. If you have actually caught something I'd take it to you county Extension office (extension.org) and they will send it to PSU for id.
