Re: [NatureNS] picaridin?Hi Phil & All,
I am interested in your comment that "...of course, anything that =
comes as a lotion and ends up on the palm of your hands is NOT safe for =
use handling plastics and is useless for fabrics in the field)."
For years I used a bottle of 95% Deet (lotion) mostly to repel =
Yellow Jackets when working near a damaged nest by rubbing a drop or two =
on bare shoulders, neck and hat; avoiding glasses and rubbed my palms =
reasonably clean on my pants. When I ran out last year I was able to =
find only 23.75% Deet in a pump container and have as yet not used it.
How does the interaction of dilute pump formulations with fabrics =
differ from that of concentrated lotions ? How does one use one of these =
pumps so the squirt doesn't go where it is unwanted; e.g. as an aerosol =
on glasses ?
Yt, Dave Webster, Kentville

Here the lowest DEET concentration I can find in a pump (non-aerosol, =
