when we go camping about 3 days ahead I take high qualities of vitamin b12 bugs don't like it. We also use camphor wood they don't like the smell at all. You could even try some camphor oil. If at home and you are being bitten try to spray Avon skin so soft on your screens they don't like to come through it. worth a try I would say. Check the health food store I'm sure you'll find more remedies. good luck
