Web-building spiders create elaborate webs for catching prey (wandering spiders chase after their prey, rather than building webs). Over time, however, mechanical stress and dust accumulation weakens the web, forcing the spider to abandon it and build a new one.

Why are there cobwebs in the air?

Ballooning, sometimes called kiting, is a process by which spiders, and some other small invertebrates, move through the air by releasing one or more gossamer threads to catch the wind, causing them to become airborne at the mercy of air currents and electric fields.

How do you tell if it’s a cobweb?

Check for an irregular web.
