Great thread!! Normally I keep my 24' FourWinns Funship in my pole barn with "no" mouse issues. I just had a full, waterline cover made due to having no other protection at my cabin 175 miles away. I'm concerned about pests protection against mice, squirrels, etc.. Even though it's a full cover, there are areas in which mice could get in. As for sticky traps, I have used them in the past (not in a boat situation) which worked great. I will definitely place a few around the inside. As for moth balls, they do smell bad. I would only place them in the engine compartment as some has stated. With peppermint oil, I have read that it only lasts about three to four days before needing to re-apply. Fabric sheets seem to be a great deterrent as well. I did read somewhere that a person ended up fabric sheets as a mouse nest. I was really hoping that an ultrasonic device (link below) would work, but it appears that they are hit and miss just like everything else. Please keep chiming in with your thoughts, ideas and what works for you. Thanks, Ray
