they are determined little buggers. If you have an old peanut butter jar, hang that high in a tree. It drives them crazy.
Maybe around here they will think winter's back and go back to bed. It was cold in the house this morning so I got up to throw a few chunks of wood in the stove (needed it bad last night ... the house was really cold). Looked out the window and there was a half inch of new snow on the ground. Checked the thermometer and it said 29šs. At least the gnats and mosquitoes got a surprise. They were getting thick already.
