My best buddy and I used a tried and tested technique perfected by assault teams in law enforcement and armed forces around the world.
We disoriented and crippled the subject from afar (e.g. flash bang, tear gas grenade) by stomping loudly on the deck and then shooting it with some teratogenic bug killer spray. Then only once it should clear signs of near complete debilitation, did we bother to approach closer than 6 feet and smush it with a long 2x4.
I am a skeered-of-spiders-sissy.
