I just got back for Bass Pro Shops and asked them the same thing. They said Deet is the best thing to use, and that there’s no sunblock/repellant that works that great. He said that one could put on the sunblock on first, then the repellant. Going fishing now and will try this.
If I sprout a third eye or something, I’ll report back.
Sounds like old wives tale, but it does work for some (not all) people:
A product from Avon called “Skin so soft” marketed as a ladie’s skin cream.
I thought this sounded silly, but a lot of people in Florida Keys swear by it.
Doesn’t have any strong chemicals like some repellents - guess mosquitos think it stinks:-)
