The suburban lake I live on is getting crazy about preventing Zebra Mussels. They are targeting fisherman and as the only tournament guy that takes my boat on and off the lake regularly I am in the bullseye. We have great fishing here (20-25 lb sacks about any day!!) so I am all in on protecting the resource but want to get in front of this before they close the ramps or something like that. I understand how to clean the boat/trailer and the recommended drying time but my real concern is about the bilge and livewells. I drain both before I leave the lake but there is always a little water left in the bottom and/or the hoses. Is there a cleaner, additive or spray I can use in the bilge and livewells to kill these little devils? Thanks for your help.
