To be honest I cannot see the contribution that spiders make to the world. All this rubbish about eating flies is nonsense as most of us clean away the cobwebs. As far as I can see cobwebs are the only way for a spider to catch a fly. I can honestly say, and I am pleased about this, your average English housespider does not jump into mid air grabbing flies as it goes. ( shivering at the very thought) This is mind, how do they do any good? They string webs around in hard to see places so we walk in to them. ( this may cause hysteria in some people .... me!) and do little else that I can see apart form lurk around waiting for victims.
At 5.30 in the morning a few weeks ago, when confronted with a psychopathic, killer arachnid in my toilet; I knew I had a fight on my hands The rather large furry beast that I had encountered had come with one intention..... to kill everyone that he could find. I knew this because he was weilding a large baseball bat (really). I am not saying he was a little scary, I am telling you he was a monster with eyes like saucers and fangs like a acouple of ice picks. A scuffle ensued and the hellmonster was slain at the hands of a broom weilding maniac. Another eight legged attacker dispatched to spider hell.
My advice to anyone who thinks to attack me at 5.30 in the morning; do not hide behind the toilet cleaner bottle!!!
