It is the same here, and believe me I would never move these things outside our area. the few times a year that I go north to where they haven't gotten to yet I make sure to do a good clean on my live well and hoses before I go. Having said that the Niagara Peninsula is completely infested and a personal pond is the only water that you might not find them in. Actually with the number of ducks geese and Blue Herons we have I will be surprised if they don't end up getting in anyway.
