SEATTLE — Believe it or not, most houses likely have spiders in them before they have people.

That’s because their egg sacks travel on building supplies and moving boxes as the house is built. In fact, spiders and homes go together like chocolate and milk. Records show spiders have lived in human dwellings since at least the time of ancient Romans.

But they’re not always welcome.  And as fall approaches, they’re more and more visible.

Homeowners shouldn’t be concerned, though. Rod Crawford, an arachnologist with the University of Washington Burke Museum, said native species are more often seen this year as they become sexually mature and look for mates.  That doesn’t mean they’re more aggressive.

Crawford recommends those who are really scared go around their home with a caulking gun, filling up all the cracks around baseboards where spiders usually get in.

"That will not only keep the spiders from running around so much, it will also do wonders for winter insulation," Crawford said.
