Spiders may be beneficial outdoors, but they pose real challenges in warehouse environments. Their webs often accumulate in hard-to-reach areas, like rafters, shelving, and corners, creating sanitation issues and potentially violating hygiene standards, especially in food-grade or pharmaceutical facilities.
Beyond cleanliness, spider activity can damage a company’s reputation. Clients and inspectors expect spotless, pest-free environments. A single sighting can raise concerns about broader pest control lapses and lead to failed audits or even lost business.
Spiders also signal a deeper issue: the presence of other insects. Since they feed on bugs, spotting them indoors often means there’s an underlying pest problem that needs to be addressed.
While most spiders are harmless, some species—like the brown recluse or black widow—can pose health risks. Even non-venomous spiders can cause discomfort among staff, impacting morale and productivity.
Spiders like warehouses and factories because they offer many places to hide. The large, dark spaces and quiet corners are perfect for spiders to build webs and nest. They are also attracted by other insects that they can feed on. If not managed, industrial spiders can multiply quickly. Warehouses with less foot traffic make it easy for them to stay hidden until their numbers grow.
It can be hard to spot spiders in manufacturing facilities or warehouses right away. However, there are clear signs of spiders in warehouses that can help you figure out if you have an infestation.
Here are some signs to watch for:
If you notice these signs, it's time to act and call commercial pest control for help to manage the spider infestation.
Different types of spiders can be found in your warehouse or manufacturing facility. Some are more common than others.
The common house spider, also known as Parasteatoda tepidariorum, is in the family Theridiidae. It is often found in warehouses. This small, brown or gray spider builds messy webs and prefers dark, quiet spots like corners and behind equipment. While not dangerous, it can become a nuisance in large numbers.
The cellar spider, often called “daddy long-legs,” has long, thin legs. It can be found in dusty corners and storage shelves. While not dangerous, these spiders make messy webs that can get in the way.
The wolf spider is larger than other spider types. It doesn’t make webs; instead, it hunts other insects. Wolf spiders are more aggressive and can be a problem in cluttered warehouses or storage areas.
The yellow sac spider is pale yellow-green in color. It can be found where there is food or moisture. Although it can bite if disturbed, its bites are not usually harmful.
