In reply to CJD:
If you get loads of bites you either get sensitized or develop a tolerance. If, like me you combine a magnetic attraction for the evil tormenting critturs with increasing sensitivity then I guess you get to hope for a part as an extra in the elephant man. On the other hand it makes you very popular with everyone else as the horrid things are too busy biting you to bother with anyone else.
Suggested remedies of vitamin B - doesn't work for me at all and given the amount of marmite I go through you'd think it'd have every chance.
Deet you need to watch as it is inclined to damage nerve endings and anything which can melt plastic.............. (got in trouble with an indian taxi driver for melting his seats once.) You could try wearing it on wrist/ankle bands though.
Loads of people recommend Avon Skin-So-Soft dry oil moisturiser. It seems to work for midges but not mosquitos or ants and you have to reapply every 90mins or so.
Lavender oil seems to do the trick for southern midges and those in eastern scotland but has no effect on the west coast.
Myrtle is remarkably good a fending of midges but the wasps love it so take your choice....
I'm supposed to ber reconciled to scars and unplanned "face lifts" though it doesn't stop me complaining incessantly and particularly bitterly when stuck on a belay ('s a good argument for first shot at the lead!).
If anyone has magic remedies, please, please we want we want.
