RE: Mosquito Repellent?
DEET is a good, no make that excellant repellant, yet it has a strong odor so it needs a stong cover scent.
Permanone has no odor, but it is not a repellant. It will kill the skeeters that land on you, but will take around 5 minutes to do that. Pretty soon more skeetrs take their place. It will also kill ticks, fleas. flies,etc.
Your best protection is being high in a tree.
FOOLPROOF?
Never underestimate the power of a fool!
