Wow! Thanks barx, That's something I would never have guessed. I just looked at the bottle I have now and the type of areoguard I'm using is the spray type and from what I can gather using chem data actually contains picaridin as a substitute to DEET. Ingredient list of Aeroguard bottle - water, alcohol denat.(methylated spirits if I'm right),picaridin. I found this link to the info. -

My brother recommended Off! and I'm not sure if that has DEET ( haven't used it yet or seen an ingredient list) but I have just seen a website that referred to it having it as one of its components. So buyer beware and check your bottle hey!
My heart did a backflip when I read your post and it is some great info Barx. Phew I had visions of my telescope melting in front of me! I will still be careful with the spray and probably change it for roll-on just in case picaridin has the same effect!
Cheers Simmo
P.s Jen I'm not sure i've been good enough this year!
