A huge spider walked across my living room floor one day, I jumped up grabbed a colander and trapped the beast. I then went looking for something to kill it with, I could only find air-freshener but concluded that as it has eight armpits it probably needed a touch 'deodorant' which would hopefully suffocate the monster. Mr Cake was away on business and the colander remained in the middle of the living room floor for several days until I was sure it was dead or at least too weak to run away when I gingerly lifted the colander to suck it up in the hoover.
p.s. Don't wasps send out a pheromone funeral invitation when they die???
