combine 50% Coconut milk with 50% vinegar spray and kill
Ok I'm all for not killing animals or insects but if it is really threatening your life use hairspray which will get it all sticky/frozen and kill it instantly! Then throw a blob of wet toilet paper or paper towel on it, smash it a bit to make sure and throw it away. Badaboom Badabing! But if its not a life threatening situation just catch it in a cup like everyone else suggests put a lid or strong paper over it and release it back into the wild.
Catch her in a container and take her outside. There is no need to play God with any living creature. You may not like the spider, but she values her life as much as you value yours.
I drown it in spray and straight down the sink.
Crush it with your goggle
I like to shoot 'em with my 12 gauge
Throw a shoe and run like h(e)ll
Take off your shoe and use the shoe to smash the spider.
