We live near Lake Erie and the air is moist. There are lots of spiders congregating on my house when it becomes warm out. My wife had me killing about four a day last year so this year I'm taking action. I don't want spiders on my house, they are gross and they freak my family out.

You can't guarantee a completely spider proof home, but by sweeping, buying insect repellent and applying it twice a year, you can dramatically reduce the infestation.
