I have a historic sail boat… southcoast 25, first one ever built. I'm restoring it to orriginal condition, but I have a problem. it's infested with many many generations of spiders. I think there are about 50 varieties and all feeding on eachother. Before I begin restoration, these inbred things need to go or be killed. any good suggestions on how to exterminate these things on a boat? I find them nesting in the sails, the fore decks, in the planking of the cabin, the bilge, engine hatch, gear lockers, everywhere!
