Why Do Spiders Web Around Outdoor Lights and Decks?

Spiders are part of life, so seeing the occasional eight-legged creature around an outdoor area isn’t so uncommon. However, multiple spiders or recurring issues could signal a larger problem. Sometimes, that problem is simply an infestation of other insects that spiders hunt, like moths, flies, mosquitoes, and other flying bugs. 

These pests typically concentrate around outdoor lights and lit windows, especially ones with cooler lighting. Spiders then follow their natural prey, often building webs near these areas because of the abundance of prey. For this reason, the most useful target during spider control treatments is the prey or harborage pattern rather than the light fixture itself, which helps prevent spiders from building webs around deck rails, eaves, window frames, and doors. 

Why Lights, Screens, and Deck Structures Become Spider Hot Spots

Remember, spiders are natural predators of flies, moths, mosquitoes, ants, and other insects, many of which congregate around lights, screens, and deck structures. Therefore, where there are insects, there will also be spiders. Typically, they’ll build their webs in sheltered, low-disturbance places such as eaves, decks, garages, basements, storage, window frames, vegetation, and corners where they can easily hide.

While spiders can look a bit scary to some people, keep in mind that most spiders that appear around homes are nuisance predators rather than dangerous pests. In fact, according to the University of California Statewide IPM Program (UC IPM), spiders don’t even seek people to bite them; more often, they do so to defend themselves or “bite instinctively because it mistakenly senses that an insect has been caught.”

How to Reduce Spider Activity Around the Home

If you’re looking for ways to get rid of spiders, we can offer a few tips you can implement independently. Here are a few steps we recommend starting with:

• Remove webs and egg sacs where practical
• Seal gaps around your home’s exterior and repair screens
• Reduce clutter and potential harborage areas
• Keep vegetation and debris from creating sheltered contact with the structure
• Reduce the prey insects that support spiders

Repeated web removal alone will not change the conditions attracting them, which is where professional treatments can help. Always use caution when moving long-undisturbed stored materials, firewood, boxes, or outdoor equipment.
