Does Anyone Know How To Kill Spiders?

Over the past two days, I have seen a total of five spiders, all at night. Two were in my bed and three were in the bathroom. Now, you have to understand that these spiders are like Godzilla-sized! When you kill them, you have to use a shoe because a piece of toilette paper is too small! I can't explain how scary they are! But Sarah, my host sister, thinks it's a good thing I saw so many spiders at night. There is a famous French saying:
"Araignée du matin, chagrin,
Araignée du soir, espoir."
That means, if you see a spider in the morning, you are going to cry; but if you see a spider at night, you should be hopeful.
