Cobwebs and spider webs are different things. Spiderwebs are spun from their silk, and you will usuallysee the spider at home in the web. Cobwebs are a mixture of dust and whatever glues the dust together-sorry-I can't be more specific on that part.
So what exactly is a cobweb? Unlike spider webs, which spiders use to catch and trap their prey, cobwebs are vacant âhomesâ spiders have abandoned to move onto better pastures â in this case, usually just a new area of your house.The stray spider silk left behind is incredibly sticky and a magnet for pollen, dust particles and other debris.et creative and use a rubber band to attach an old sock or cleaning cloth to the end of a broom or yardstick. If cobwebs have found their way onto curtains or other fabric, follow the vacuum method and then use a lint roller to pick up those remaining sticky strands. Always wash the fabric if you are able to.
