What Makes Those Areas Good Spider Habitat
Spiders can be drawn to homes and basement areas in Concord for a number of reasons. For starters, spiders are predators and will follow their prey to ideal locations. As flying insects gather around areas where lights attract them, they act as beacons and encourage spiders to build webs or live within spaces nearby. Active hunters will use nighttime to catch their prey in basement and indoor areas, while web builders will create webs near strategic locations of heightened pest activity.
Sheltered areas are also ideal for spiders as they avoid predators and natural elements. Areas that provide protection from wind and rain can become ideal locations for building webs, which can lead to an increase in spider webbing around window frames, ceilings, or inset basement windows. Landscaping can also provide spider and pest habitats and can lead to indoor pest activity when placed against foundational areas.
While most spider activity in Concord is not dangerous, their ability to lay dozens to hundreds of eggs can lead to an increase in spider hatching and breeding, resulting in a population that can be difficult to maintain or control.
How to Reduce Spider Activity Around the Home
There are a few steps that Concord residents can take to reduce spider activity within the home and basement areas. Spiders are attracted to areas where shelter and access to food can easily be found. Reduce the presence of clutter or boxes around the basement areas to deter pest nesting and areas where spiders can create webbing to catch prey. Promptly repair leaky pipes and address areas where moisture and condensation can attract crawling insects such as cockroaches and ants. Seal cracks and crevices that provide small points of entry where pests and spiders can enter your basement areas.
In outdoor areas of your Concord home, remove leaf litter from foundational areas and trim bushes and brush away from the structure of your home. These conditions can contribute to areas where pests can harbor and attract spiders. Dump standing water from around the yard and remove leaf litter from gutters and downspouts to reduce areas where mosquitoes, flies, or gnats can lay eggs. Relocate firewood away from building structures and consider using gloves or long-sleeved clothing when relocating items which have remained undisturbed for extended periods of time.
