however, when they're as big as your hand with your fingers spread out wide, i don't rEally know how to go about catching them...and with my brother scared of them as well, it's a brush away the spider fest in my room...
I had to catch one for my lessons biology. I had to kill it with some chemical products and then I had to draw it by looking at it through a binocular. It looks very interesting when you look at it closly.
Normaly I do what Josh said. Catch them and put them outside. They can be very useful indeed.
I do crush musquitos though.
