Dealing With Spiders in Centennial’s Finished Basements

By Gerald Gilbert 1 week ago

Many Centennial homeowners invest in finishing their basements to create entertainment rooms, home offices, and guest suites. There is, however, one intruder that never pays for an invitation: spiders. Even after a beautiful renovation, eight-legged creatures still find their way into homes, spinning webs in corners and scaring residents during movie nights or workouts. It gets even worse when you have invested thousands in creating a living space, only to have spider webs appear more quickly than you can remove them. Although DIY might provide an interim solution, ongoing spider issues in the finished basements of Centennial, often due to full infestations, frequently necessitate specialist treatment from Saela Pest Control to address the source.

Why Finished Basements Attract Spiders?

Moisture Retention

Finished basements are even better at trapping moisture than unfinished ones. The drywall, carpet, and insulation form pockets that hold humidity, the exact environment that spiders love to hunt prey in.

Hidden Entry Points

Building materials often leave numerous small holes around windows, pipes, and electrical outlets. During Colorado’s temperature swings, these small openings become highways for spiders looking to escape the elements.

Food Source Availability

Other insects that are attracted to the basement become a buffet for spiders. Regular meals are supplied by silverfish, carpet beetles, and flies that enter through foundation cracks, recruiting spiders to become lifelong residents.

Undisturbed Corners

There are many quiet spots behind furniture, entertainment centers, and storage in finished basements. These undisturbed areas allow spiders to weave webs without disturbance.

Temperature Stability

Their steady atmosphere allows them to be year-round shelters. Other areas of your home or outdoors are in constant fluctuation, but your basement has nice, steady conditions, which spiders love just as much as you do.

Environmental Factors That Make Centennial Basements a Hotspot

The semi-arid climate of Centennial, with an annual precipitation average of around 17 inches, presents its own unique challenges for controlling basement spiders. Perched at an elevation of 5,680 feet, the city experiences temperature swings up to 30 degrees between day and night. This boundary causes spiders to go secure indoors. The subsoil is rich in clay and expands and contracts with changes in moisture, which can cause the foundation to crack and provide an entry point for water. Homes in Centennial’s Southglenn and Smoky Hill neighborhoods date back to the 1970s and have undergone various phases of development throughout the 2000s. 

How to Prevent Spider Infestations in Finished Basements

  • Seal up foundation cracks and open spaces around windows, doors, and where utilities enter your basement. Install weatherstripping on basement doors, and seal any gaps larger than 1/8 inch with caulk.
  • Clear floors of clutter and storage bins. Store your belongings in sealed plastic containers instead of cardboard boxes. Avoid placing stored items against walls and allow at least six inches of space.
  • Use a Vacuum on Routine Areas like corners, ceiling edges, and behind furniture. Eliminate old webs as quickly as possible, as spiders could lay egg sacs in them.
  • Install door sweeps on all exterior basement doors and ensure window screens are tight-fitting and free of tears or holes.
  • Reduce outdoor lighting near basement windows and doors, as bright lights attract bugs, making it easier for spiders to follow.

Why Professional Pest Control Is the Smart Choice

Success in treating spider infestations depends on understanding the behavior & entry points that homeowners often overlook. Professional pest control technicians inspect foundation perimeters, crawl spaces & HVAC systems for access points that spiders are using to enter your finished basement. Saela Pest Control offers Centennial spider control that will eliminate current spiders and kill their food sources, so you can interrupt the cycle that brings one spider after another.
