This looks like a type of wolf spider. Wolf spiders do not make webs but hunt their prey on the move. Most wolf spiders hunt at night but occasionally they can be found during the day.  These and other solitary spiders normally enter the house near ground level and are normally encountered in basements, crawlspaces, and breezeways. These spiders occur in very low numbers, and usually homeowners encounter only one or two of them. It is normal to find a spider or a few in the home every now and then. It appears you've already set up a sticky trap, which is a good start for low-maintenance spider and indoor pest control.
