Spiders seek out dusty spots in your home as a form of preservation. Clumps of debris act as a safe spot for their nests, and hard-to-reach areas help them avoid detection.
Spotless kitchens that lack fruit flies and have immaculate recycling containers without a single mosquito create an environment that makes it difficult for spiders to multiply.
Dusting is a proactive means of reducing spider populations, provided it's done regularly. Ideally, aim for a biweekly dusting of areas where cobwebs accumulate.
Spider webs can be eliminated by attaching an extension wand to a vacuum cleaner to reach high corners and spots behind furniture. Be sure to dispose of its contents outside.
