My boat and trailer are moored in my yard and the biggest bug problem I have is spiders- particularly in August. That is true of my house, too. I have a heavily wooded yard and in August spider webs are everywhere. I can walk through 3 or 4 going to my workshop, turn around, and walk through a couple of rebuilt ones before I can get back to the house. A few dryer sheets placed around keeps the spiders out of the boat. I just have to wash them off the exterior before I go sailing. -Paul
