How Light, Shelter, and Moisture Can Concentrate Spider Activity

The Biggest Spider Attractant Is Usually Food

Spiders are a frustrating pest for Norfolk residents to manage. Aside from the creepy feeling that residents experience, there’s an additional element of spiders using strategic locations to build their nests and hide. High ceilings, basements, and rooflines create ideal web locations as spiders migrate to areas where shelter and food sources can be found. Eaves, rooflines, water meters, and indoor spaces provide shelter from wind and predators, while outdoor lights create an abundant food source as flying insects are drawn to the light source during dusk or dawn.

Moisture can also contribute to spider activity because of the pests it draws in. Mosquitoes, gnats, and cockroaches prefer damp areas where water and decaying vegetation create ideal nesting and breeding conditions. As leaf litter, brush, or stagnant water collect around Norfolk properties, they increase the amount of insect pest activity and ultimately attract the spiders that prey on them. Fortunately, the majority of spiders found in Norfolk are not medically dangerous, although an increase in activity can point to a much larger pest problem overall.

How to Make the Area Around Your Home Less Spider-Friendly

It may be difficult to reduce the presence of spiders at your home in Norfolk, but there are steps you can take to make your home less hospitable. Spiders are natural hunters and will follow their prey to ideal locations. As insects gather around external lights found on garages, porches, and back decks, they act as a beacon for spiders. This can lead to an increase in spider webs found around these areas. To reduce this, consider using bug zappers or replace external light bulbs with yellow bug lights to deter flying insects from gathering nearby.

For quiet areas such as attics, basements, or garages, ensure that the areas are free and clear of stagnant clutter. Boxes and empty containers should be properly stored and regularly checked for signs of spider webs. Remove leaf litter, firewood, and brush from areas near foundations or walls where spiders can use them to easily access cracks or gaps around the home. Additionally, clearing litter and brush helps to remove areas where spiders can nest and hide as they hunt for prey.

Seal points of entry around windows, utility lines, siding, and doorways where spiders can enter your indoor living spaces. Conduct spider web sweeps on a recurring basis to remove old and new spider webs, and promptly remove any signs of egg sacs found around the home.

When Persistent Spider Activity Points to a Bigger Pest Problem

While spider activity can provide a source of natural pest control, they can also create a bigger headache for Norfolk residents. As spiders become established, residents will notice an increase in sightings, webbing around the property, and egg sacs which signify continued breeding and growth. These instances can lead residents to seek professional spider control services to reduce and disrupt the breeding and growth cycle.
