Anybody heard the phrase "a ship in mothballs" ?
USN procedure used to be to put big mothball blocks (camphor or para) in a stored ship. They both sublimate at room temperature, and leave a very slight film on everything that prevents corrosion. And, especially para, the vapors are toxic to pretty much anything, so it repels bugs, squirrels, even deer. Note, toxic to humans too.
I take a couple of boxes of mothballs and scatter them in the bilge, in the mast, everywhere including in the sails before packing them up for the winter. In the spring, you have to open some ventilation and then gtf out of Dodge while the vapors are being cleared out. But you'll probably find that nothing has made a home in the boat, or the sails, if you've used mothballs. Which Grandma would be amazed to find, the EPA classifies as an insecticide and hazardous material these days, because it does the job so well.
