Now I normally just take spiders out - they are good things to have and eat flys and other things, but this one was bigger than I wanted to touch. I didn't have a glass or anything I could see to catch it under. What was I to do?
I found an envelope and, at the second try, a supermarket plastic bag without a hole in the bottom. Then I used the envelope to herd the spider around ... up the wall in a gravity defying way until I gave gravity a help and it fell into the bag. Then all I had to do was keep shaking the bag to stop it climbing out and head for the front door, turning lights on along the way so I could see if it was escaping. I was barefooted so walking over the front mat was a bit like crossing a bed of nails :) When I got outside I shook the bag ... nothing ... so I shook it again ... still nothing. Finally I tilted the bag over slowly and the spider plopped out and scuttled away over the lawn.
Right, off to bed now.
