Emma, that is helpful, thanks. It would seem that the risk is fairly minimal in reality but I still can't wholly erase those images of plastic bags dissolving before my eyes. I'd imagine that I'm probably more at risk from using mosquito coils in an enclosed tent and breathing in the smoke, something which I am inclined to do when camping in the height of midge season.

Phil, it's the effect on the Botox injections which I'm worried about....

Picaradin (active ingredient in Smidge and Autan Protection Plus) is supposed to be as effective as DEET but non toxic and doesn’t melt plastic http://www.outdoors.org/articles/amc-outdoors/picaridin-vs-deet-which-is-the-best-insect-repellent/

Ta Robin. So Colin's good looks are safe! :smiley:

I am fortunate in that my wife has assured me that I'm naturally repellent.

:confused:

I use Smidge which I’ve found to be excellent. Claims to repel ticks too

Two years ago I stayed at Rowardennan YH, Loch Lomond. There was a cloud of mosquitos (not midges) outside. I decided to try out the Avon Skin-so-Soft, covered my arms and went outside. My kids were watching from the inside. They saw the cloud of mosquitos move aside as soon as I moved into the cloud. Succes ! But not real midges. This year I was with my son at the south end of Loch Treig and we were attacked in full force by midges (the real ones). I applied Avon Skin-so-Soft and my son applied Smidge. Neither of us was bitten severely but while the midges didn't come closer than 3 inches to me they landed on my sons arms and face. They took off almost immediately but it was very annoying for him. So AvonSsS will do the trick for me.

My wife or loved one is an Avon lady and the "skin so soft" stuff is actually a range of products and not just the one. Some of it has insect repellent in it and some of it doesn't. The stuff that doesn't does drown midgies, though. You have to read the labels.
Bing bong.
