Prudie, I have to control my instinct to scream and run away from spiders. I have to remember that they are useful and catch flies etc.. Everyone tells me so.
You don't feel them, that's the problem. I don't know exactly where I was when I was bitten. You get a bit of an itch, push your sleeve back or whatever - and there it is. Mine have quite a lot of blood under the skin as well as if there is an anti-coagulent concerned. Not a bit like a flea-bite and I've only had these in the last few years - apart from a really nasty one in France once.
Global warming?
