That is literally the only way to kill them in Australia. One time my uncle tried to use a shoe, the spider took the shoe off him and beat him to death with it. Then my Aunty gave it a try, poor Aunt Stacey, attempted to spray it with bug spray BUG SPRAY was she insane? it consumed all of the poison and just got bigger then drained her of her life force using the can as a fucking straw. My father got it worse though, he tried washing it down the drain, the nursery ryhme said it was a good idea HAHA fucking liars after it waterboarded him for an hour it murdered him planted even more spiders in his corpse and when those fuckers spawned we realised he hadnt been dead at all, oh the screams. Seriously even a bazooka is not overkill for these fiends.
