There are thousands of species of spiders, and they are one of the most common insects on the globe....2nd only to houseflies. In most temperate regions, most people are probably no more than 10 feet from a spider...at home, or outdoors...at any given time. Unless they are poisonous, they probably do more good than harm....as they consume large quantities of other insects.
Around here we have a few Black Widows and Brown Recluse spiders....which can be quite harmful if they bite a person. I sometimes see one in my workshop....none in the house, so far...and I just scoot them out of the shop with a broom. I just let the non poisonous ones do their thing, and periodically sweep up the carcasses of the bugs they've fed upon. We get some in the basement/garage, and they migrate to the windows, so I just suck them and their webs up with a small vacuum cleaner, periodically.
About the only time I find them a nuisance is when I'm mowing the yard, or driving the tractor through the forest....I often run through a large web strung between the trees....usually can't see the web until I'm covered with it.
