My attitude to "outdoor" spiders that make it "inside" is to perform some natural selection. If you catch and release the ones that get inside, you are putting genetic selection pressure on the species to prefer offspring that have a tendency to come into houses. I prefer to put negative selection on these by terminating the genetic line. That way, only spiders that prefer to stay outside are the ones that will be allowed to procreate! After many generations, spiders won't come inside
