APPENDIX II-L: Non-toxic methods to ward off mosquitoes:
Bob, a fisherman, takes one vitamin B-1 tablet a day
April through October . He said it works. He was right.
The odor the tablet gives out through your skin
(YOU can not smell it) repels mosquitoes,black flies,
no seeum's, and knat's. It does not work on stinging insects. Hasn't had a mosquito bite in 33 years. Try it.
Every one he has talked into trying it works on them.
Vitimin B-1( Thiamine Hydrochloride 100 mg.)
This is going to floor you, but one of the best
insect repellents someone found (who is in the woods
every day), is Vick's Vaporub.
Plant marigolds around the yard, the flowers give off
a smell that bugs do not like, so plant some in that garden also to help ward off bugs without using insecticides.
