Now the body is the size of a wasp. Surely this is not a normal common spider in switzerland. I have been here 6 years and never seen anything of the sort.
I am not scared of spiders but there is not a chance that i am going to attempt to get rid of this thing!
If you aren't going to trap and release him, then the death must be sure and brutal.
Spiders are extremely tough little b@stards. Couple months ago a ~2cm one was scampering across a work table; snatched him up with tweezers and dropped him in a beaker of acetone. Acetone. He ran around the perimeter of the bottom of the beaker for a good 10 seconds... I had to admire him so I pulled him out, dropped his groggy self on a paper towel and took him outside. A few minutes later he got up and marched off. Like a boss.
