All spiders bite!!!! We just don't have any particularly poisonous ones in the UK.

I've got a doodad that has foot long tube and a small extractor fan at the bottom, you suck up the spider and then throw it out. We only have problems with the really big ones that won't fit in the tube...........

I may have a go on the sonic thingy, but what I've found most effective is checking the garden through the summer for nests and egg sacks and relocating them to the dump.
