When I lived in Europe I had a pact with the spiders in my home. They would stay up on the ceiling and I would not bother them but if they came down they had to die. They knew what they got themselves into.

Now I live in Africa and have a strict “no spider anywhere in the house” policy. Some spiders here can be rather unpleasant roommates. (The exception are jumping spiders. They are mostly nice and can stay if they do not come too near)
