I tend to treat spiders fairly. If they allow themselves to be caught they get thrown out the house and live. If they resist they get squashed. The size of some of them though a bit of googling would be in order first though to see what they eat, eat meat they will just get squashed/skewered out of hand.
Biggest one we have had so far is no more than 1.5inches so very much a different league to these suckers. I do think though the first one wasnt a real spider.
If I told you the size of some of the spiders that we get up here you would probably not believe me!
I usually try and catch them if I can, and put them out. Some of them are just such a big size, I tend to think of them more as a small animal, with a life to live, rather than a creepy crawley to be squished.
