Can Spiders Really Help in an Energy Audit?

They often spin webs where outside drafts come in

Q. I've heard that spiderwebs in a home can be a clue to drafts that should be plugged with insulation. Is this true?

A. Yes. To trap prey, spiders often spin their webs in or near gaps in walls and around windows. That's because the gaps convey drafts that bring in food in the form of tiny insects. And winter cold and summer heat comes in too, raising your energy costs. So spiderwebs are one clue professionals use in home energy assessments. You can plug the holes you find.

You may qualify for government aid to improve your home's energy efficiency. See what's available in your state at this U.S. Department of Energy website.
