I have some kind of invisable bug in my frontroom. It stays in the frontroom and does not go into the other rooms. It comes out in the evening. When you get it wet it is black. We put them in a bowl of vinegar and they turn orange. We have been trying for months to get rid of it and nothing has worked. We wash walls with amonia and vinegar and that seems to stud them. Other wise you can't see them but you can feel them fly by your face or arm. We got a free couch from a farm and we think they came from that. I have got rid of the carpeting and other stuff but we still see to have some left. I have tried all kinds of chemicals. Any help I will appreceate thank you kathy I have had it professional sprayed also.

Until you can have them identified, you cannot eliminate them. Collect some specimens in a jar and take them to an entomologist. Normally you can find entomologists at Universities, government Dept. of Agriculture offices, and at some large exterminators' offices.

Once you have a species, you will know what their food source and resting habits are. Eliminate those two and the insects will die off.
