Signs of a Spider Infestation
The easiest way to spot a spider infestation in your business is to look for their webs. Check the upper corners of any areas that tend to be dark and damp, as spiders enjoy those types of environments. Spiders build webs around insect thoroughfares, where they’re most likely to catch prey. You might see cobwebs around door frames, window wells, baseboards, storage containers, and vent systems.
Different species of spiders build different types of webs, but they all have several common characteristics. If webs fall, you may see them in clumps around the floor in basements, crawl spaces, or warehouses. Spiders also tend to build webs in areas where they won’t be disturbed, so look for them in out-of-the-way places.
Note that spiders follow the food; if you’re seeing an increased number of spiders, you might have another pest infestation happening beneath the surface.
