No totally correct. Just wait until they have babies and you have thousands of them. Flying through the air trying to catch the wind. Blowing all over you. Climbing on everything. Leaving webs in every nook and corner of your house when they finally find their way in, which they will. Not to mention their are other spiders that can be more vicious or dangerous that will eat these spiders. So you will be drawing those really bad ones in too.
The answer is to kill every single bug and spider in the vicinity
