Of all the creepy-crawlies that may come aboard your boat, spiders are often among the least welcome. Spiders are especially common during summertime when the warm weather brings with it an abundance of food - namely, other bugs. Whether you're an arachnophobe or not, large numbers of spiders can seriously mess up your boat. This is because, besides leaving webs everywhere, spiders also poop a lot. Their grayish, brown or black droppings look like tiny dots and can cover the entire exterior deck and if they find a way in they'll mess up the interior as well. If wiped up immediately, spider poop is no problem. However, if left for even a short time, these tiny droppings will harden like concrete to form a crust that's almost impossible to lift. Even if you do manage to chip away at the mess, spider poop can leave stains that permanently damage the aesthetics of your boat.

One of the most effective ways to cut the number of spiders on your boat dock is to apply an effective spider spray. The best of these are designed to take down both spiders and other types of insects, as this also eliminates their food source and reduces the likelihood of them coming aboard.
