It sounds like you live next to a lake or a body of water. The best thing to do is to first - remove the spider webs. Wash everything down, brush it down with soap and water, or a high pressure sprayer. We sell the CobWeb Duster to make reaching eaves and such a little easier. You may even consider using EcoSafe Cobweb Cleanup, it helps to remove the spider spittle (black spots, etc) that they leave behind, and it also helps to repel spiders.
For a really "green" treatment around boat docks, etc, and in areas where pesticides could contaminate, use Essentria IC3 and spray everything. It kills spiders on contact and then repels others.
To really "nuke" the spiders and in areas where contamination is not a concern, use Bifen Insecticide, and spray everything.
Both of these product must be applied by using a hand tank or back pack sprayer and not a hose end sprayer. Reason is that these products are designed to be mixed around 1 oz per gallon of water and then sprayed. With a hose end sprayer, there is no way to measure how much insecticide to water ratio.
Spraying indoors for spiders doesn't do much, as you have to contact them with the insecticide to kill them. You can also spray Bifen indoors. Don't spray Essentria IC3, it has a strong floral aroma. Also use ePest IPM Bug Traps placed under furniture etc, to capture them. Replace as needed.
Do all of this every few weeks during the season, and you will be doing all you can do. Thanks.

Spiders are only killed when sprayed. In other words, spraying and then hoping they will crawl over the sprayed area and die, won't work.
You can spray them with almost anything to kill them. Alpine Pressurized is a great contact killer that is also considered to be a "green" product and ecofriendly.
Essentria can also be sprayed indoors, but it has a fairly strong floral odor. ePest IPM Bug traps are also very ecofriendly and poison free. They are also very good at capturing spiders.
