Car vacuum
A friend of mine had this problem. He got his 12 volt car vacuum out, a few times, and systematically vacuumed the webs, spiders and egg cases up. This seemed to solve the problem.Since the boat was moored during the season, he's pretty sure that they were getting on board when it was stored in his yard. So, he moved it to another location away from the trees and bushes and the problem seemed to clear up.Spiders are interesting, they can travel across open spaces (using a strand of web as a "parachute"), they can jump large distances and move very fast (some species can travel up to 40 times ther body length in 10 seconds), actually I find them pretty fascinating and adaptable creatures. Remember, they do eat a lot of nuisance bugs.Many folks think they are a nuisance, but in balance, spiders are a good thing to have around.Geof
