Yikes! 
I feel bad killing them (they eat the bad bugs, right?) so I picked him up on a piece of paper and dropped him (and the paper) out the window!
This one was so big it could have eaten a baby, when I shot it it exploded and covered the entire bath, as far as I'm concerned it was me or him, justifiable homicide.

It survived being hit with a shoe heel several times, bleach, boiling hot water from the kettle, skewered with a mop (it lost legs but kept going), hit with a hammer I threw at it (was a bit flatter but kept going), I tried putting a glass over it, but it was TOO BIG to fit one over, finally I became convinced it was some form of mutant and all my video game training came into play, one shot and it exploded like a water balloon

Yeah I know, I'm a terrible person, my room 101 is full of the various 8 legged beasts I've dispatched
