Why Do Spiders Gather Around Garages and Window Screens in Late Summer?

Why Lights, Screens, and Deck Structures Become Spider Hotspots

Spiders are predators and their presence around your Auburn home can point to larger pest issues overall. During dusk and dawn, insects will gather around light sources and act as a beacon for spider predators. This can increase the presence of webs and spiders around garages, porches, decks, and areas where large windows allow indoor light to pass through. Decks and porches help to provide shelter from the elements, allowing spiders to build their webs in areas where they avoid the detection of predators or avoid the effects of wind or rain. With minimal activity commonly found in these areas, spiders can remain undetected while establishing their webs.

For spiders that actively hunt their prey, ground level areas can provide ideal access points to crawling pests. As ants, cockroaches, and other pests make their way through small gaps and crevices, they attract spiders to follow them and hunt at night. This can lead to increased activity within basements, crawl spaces, and attic areas as well.

How to Reduce Spider Activity Around the Home

There are a few steps Auburn residents can take to reduce spider activity and the conditions that attract them. For outdoor areas, reduce brush, leaf litter, and decaying vegetation. These conditions attract flying and crawling insects such as cockroaches, flies, and gnats, and encourage them to nest and breed within damp areas around your property. Clear foliage from underneath porches and decks where pests can nest, and clear leaf litter from gutters and downspouts to reduce areas where standing water can contribute to mosquito nesting and breeding. Use caution when moving firewood, brush, or other items that have remained undisturbed for extended periods of time, and consider using protective gloves or long-sleeved clothing.

Consider swapping outdoor lights for yellow bug lights to reduce flying insect activity around dusk and dawn. Reduce clutter and properly store boxes to reduce areas where spiders can build webs and where pests can hide. Inspect the home for gaps and cracks that can contribute to spider entry. This can include garage-door corners, worn door sweeps, or windows where mesh screens have become worn or torn. If you notice egg sacs, promptly vacuum and remove them from the area to limit the continuation of spider hatching and breeding.

When to Call for Professional Spider Control in Auburn

This is where multi-pest control services can help.
