[pct-l] insects!



I have never used the time release version.
unfortunatly I am very dry skinned, and still find that the 95% Deet is still far better.
 
The study is probably valid about sweat breaking Deet down. However, I don't think I can swallow the idea that 30% deet is anywhere near as good as 70-95%, Ive had Personal experience with hungry little insects. can still remmeber people putting on 25% deet lotion and the bugs stay away from them for about 5 minutes, and I handed out some of my 95% proof to some of them, to give them some relief from the bugs for about 30 minutes. Buy them things were hungry...
 
It may be that the 25% stuff was not a good blend, or something, but other than the 95% melts plastic, I rather perfer it....
 
P.S. the place where we were "experimenting" with 25 vs 95% deet was near Banner and Ridder on the the JMT.

Have you ever tried the timed release stuff? The military did a study that
showed that concentrations above 30% added nothing. The reason that 100%
seems to work better is that sweat breaks down DEET and it loses
effectiveness. The higher concentration appears to work better because it
will take more breaking down (as a very simple explanation). The controlled
release stuff does just that....releases it over time (12 hours or so) at
concentrations of 20% to 30%. It's not to be confused with the lotions that
have "normal" DEET at 20%.
