I Asked an Arachnologist How to Get Rid of Spider Webs for Good - What He Told Me Changed Everything

"When you're deep cleaning, you've probably mindlessly cleared away a cobweb in the corner of the ceiling. And understandably so - spider webs don't exactly add to your home's aesthetic. Your mindless swipe is unlikely to have consequences for you, but it could come with consequences for the spider that took time to make it (and relies on it for a habitat)."

"For example, Crawford says cobwebs are the kind that have an apparently random collection of threads going every which way with no rhyme or reason to the eye of the uninformed viewer. Funnel webs are solid sheets of silk - they look like a slightly dirty thin piece of fabric with a tunnel in one corner where the spider hides."

Spiders create various web types that serve as habitats and hunting tools, and deleting a web can harm the spider that depends on it. About 30 types of house spiders in the U.S. can produce different webs with distinct structures. Cobwebs appear as apparently random tangles of threads. Funnel webs are solid silk sheets that look like a thin piece of fabric with a tunnel in one corner where the spider hides. Sheet webs resemble funnel webs, but the spider hangs on the underside instead of in the corner. These webs may take a few weeks to complete. If a web is destroyed, resident spiders will remain in the home and will labor to build a replacement.
