This this this. Perfect time to teach the kids not to smash every critter they might see in the house.Yea it's a wolf spider.. They are harmless just teach your youngins not to touch them..
As far as getting them out of your house for the safety of your children ask yourself this... How often do you let your ankle biters play on the grass? Wolf spiders are everywhere in every yard all the time!
Continue to catch them when you see them in your house and release them out side..
