Hey Brett, my suggestion would be to let me take them off your hands

ill take any of the ones you don't want.
As fast as the best way to get them out is to catch them when they are on the move, when they blow themselves up and are detaching, at that point you can lightly pull them off and put them in a container. If they have attached themselves your best bet is to make them want to move, the best way is point some flow at them with a small pump or extra power head
