Jean Butler @ 6:46 pm #


I am particularly interested in the little black flies. On two separate occasions, I found one or two (both times dead) in my bed in the morning when I made the bed. These had thin little wings, but I have never seen one of them fly. They usually move very slowly. The first place I saw one was in my bathroom sink, coming out of the overflow drain. This was several months ago. I sprayed with a bug and insect spray which I keep on hand, plugged up the overflow drain, and that seemed to take care of them… until last evening. I was in my recliner and I saw one on the chair arm, just sitting there looking at me. I swatted him. It was approximately 3/16″ of an inch long and the others were about the same size. If these are the same creatures that were biting me back in the spring and summer, the bite is awful. Apparently I am allergic to their bite. I made the mistake of scratching it, not knowing if it was a bite or what since I saw no sign of anything that could have bitten me, but within 5-10 minutes of scratching I had a bump on my arm the size of a large lima bean and the itching drove me crazy. I finally put clear finger nail polish on the bite, but it took about three weeks for that place to go away and it left a purple scar on my arm. I hate creepy crawly things in my house, especially in my bed…I freak out!!!!!!!! Any suggestions of getting rid of them permanently?
