How does dusty webs are formed?

Dusty webs are formed when dust particles and small debris accumulate in corners and crevices, often becoming trapped in spider silk. Spiders create webs to catch prey, and over time, dust settles on these webs, leading to their dusty appearance. Environmental factors like airflow, humidity, and the presence of pets or human activity can influence the accumulation of dust. Regular cleaning can help prevent the buildup of both dust and webs.
