This is typically the most recommended method for keeping spiders off your boat. But be cautious when using such products. You can find plenty of products that can repel spiders and insects.

However, there are products with chemicals that can damage the exterior and interior of your boat.

Harsh chemicals in spider sprays can:

Never miss a routine clean for your boat. Not only will it keep your boat clean and tidy so you can enjoy your boating experience. But it also ensures that no bugs and insects will make a permanent home, which decreases the spider’s food supply.

Despite some people’s beliefs, spiders will not get any crumbs on the floor. But they will eat the insects that eat those crumbs, like ants and flies.

Below are four tips for cleaning and organizing your boat:

  • Ensure you have no leftover food and drinks on your boat, especially when you are not using them.
  • Have a broom closet so you can clean up after when there are any crumbs and spills.
