When I go into the hen house to gather eggs, clean, etc. I usually come back inside with one or two teensy-tiny black crawling/jumping bugs on me, especially in my hair. They do not bite, but will drive one crazy moving around. Have to get in the shower or get DH to search through my hair until he finds and removes it. Usually, when he opens his fingers to kill it, it jumps off and disappears before the deed is done! The ones that we did manage to capture are not smooshy...they are hard to kill like fleas. What is this bug? I wormed my hens with Eprinex and put Sevin dust in the hen house last week, but I am still getting them on me. The hens have no sign of this bug (at least the ones I held upside down and examined). Help!
