Which of the following is a nonchemical control tool for managing spiders?

Vacuuming spider webs is an effective nonchemical control tool for managing spiders because it physically removes spiders and their webs from an area, disrupting their habitat and reducing their population. This method is straightforward and can be done frequently to control spider activity without introducing any chemicals to the environment, making it particularly useful in residential settings where chemical applications may not be desirable.

In contrast, the other options involve chemical control methods or tools that are not considered nonchemical. Insecticide sprays apply chemicals to eliminate pests, foggers release aerosolized pesticides into the air, and sprinkling granules typically involves the use of pesticide granules to attract and kill insects. Therefore, vacuuming stands out as a purely mechanical method, emphasizing cleanliness and minimizing chemical exposure.
