Do you burn those smoke fires that help keep them away? We used to do that for our horses and my sis's horse loved it and would hang his head over it and be bug free. I can't remember what they are called
not citronella - but those are nice too. I think the fire has a special name. Smokey fires. I love camping. Especially near a lake so Mav and I can swim. Steve won't go in the cold water
