We don't have any Brown Recluse in Montana either...Except for the ones that hitchhike on inbound southern and southwestern freight that delivers to our state!! Spiders of all kinds hitchhike into all Northwest states from their "home ranges"..Its just whether they can survive once they get here that determines if we "have them" or not..
