How to Identify Cellar Spiders and Their Control
Cellar Spiders: Harmless Homebodies
Cellar spiders are arachnids belonging to the family Pholcidae. They are characterized by their long, spindly legs and small, often dark-colored bodies. Their webs are typically irregular and often found in dark, undisturbed areas, such as basements, cellars, and under eaves. Cellar spiders are known for their ability to rapidly vibrate their webs when disturbed, a behavior believed to deter predators or startle prey. While often considered harmless to humans, they can be beneficial as they prey on a variety of insects, including flies, mosquitoes, and moths.
Often mistaken for their more intimidating cousins, cellar spiders are actually quite benign creatures. These long-legged arachnids are common inhabitants of homes in Kansas City, but they pose no threat to humans. Explore why they choose our homes and how to manage their presence.
What Are Cellar Spiders?
Cellar spiders are easily recognizable by their long legs. Despite their name, they are true spiders and have eight legs. They are typically pale brown or gray in color and have small bodies. Unlike many other spiders, these spiders create loose, irregular webs rather than the sticky, symmetrical webs we often associate with spiders.
Why Are Cellar Spiders Around My Home?
Cellar spiders are primarily attracted to homes for one reason: food. These predators feed on other insects like flies, mosquitoes, and even other spiders. Your home provides a consistent food source, making it an attractive habitat.
How Do Cellar Spiders Get Inside?
Cellar spiders often accidentally find their way indoors. They can enter through open doors and windows or crawl through cracks and crevices in your home’s exterior.
Preventing Cellar Spider Invasions
While cellar spiders are generally harmless, their presence can be unsettling for some. Here are some tips to minimize their population:
- Reduce Insect Prey: By eliminating other insect pests in your home, you’ll reduce spiders’ food source.
- Seal Entry Points: Caulk and seal cracks and crevices around windows, doors, and foundations to prevent spiders from entering.
- Regular Cleaning: Vacuuming regularly can help to remove spiders and their webs.
- Outdoor Lighting: Reduce outdoor lighting as it attracts insects, which attract spiders.
When to Call Professional Pest Control
For most people, cellar spiders are more of a nuisance than a problem. However, if you have a severe infestation or are particularly bothered by their presence, you may consider professional pest control.
