Hello:

Have a question re DEET.


A bit worried about the 100% deet, as I read in several places over the
years that
at this strength it is a carcinogen and should be avoided.
True ?

Not sure. Canada no longer supports sales of 100% DEET products. This is
because of rapide absortion of DEET across the skin.


Dropping down in strengths, I see iall the products seem to go from the 100%
to 30% for several 3M offerings.
Doesn't seem to be anything between 100% and 30%, surprisingly.

Is the 30 % "fairly" effective ?

Data suggets about 6 hours of repellency, but repellency is a relative
term, just means fewer bites than if you didn't use the product.
Apparently, 2 separate doses of 25% DEET provide prtection fo rthe same
length of time as a single dose of 100% DEET, with half the prodcut.

How dangerous is this stuff per any recent research ?

Any other repellents "worth" trying ?

Thanks,
Bob
