Yes, I'm thorough when it comes to tick-checking as I'm worried about Lyme's disease, but I never actually seem to have any! Others seem to get them more frequently from similar areas. Odd. All anecdotal evidence though!
In other biting mite news, I got my first few chigger/harvest mite bites of the year today. Presumably from Dale Quarry, though they might have been from Apparent North last night.
I think it was from the lime to be honest. I've never knowingly got bitten on a grit crag, but they are very seasonal and I generally tend to be on lime during that seasons, so they may not actually be fussy about rock type. They seem to like perma-dry veg at the base of steep crags. Yes, they're practically invisible to the naked eye. I've never seen one, only the bites.
I recently got these tick machines for the kids as they seem to get them the most. The send out a high pitched noise that they don't like. They weren't cheap (£30 each from memory) but after the last few years I thought fuck it.
