Regarding household pests, spiders may not be the most destructive, but they cause unease for many homeowners. Among the various species of spiders, French house spiders often make their way into homes, creating a mix of curiosity and concern. But what exactly attracts them, and how can you mitigate their presence in your home?
French house spiders are common arachnids that often find their way into homes, bringing with them a mix of fascination and fear. Unlike more dangerous or invasive pests, these spiders are generally harmless, but their presence can still be unsettling for many individuals.
Understanding what draws these spiders into homes is crucial for managing and reducing infestations. Factors like food availability, shelter, moisture, and even light all play a role. By recognizing and addressing these attractions, you can take steps to create a less inviting environment for these eight-legged visitors.
What Are French House Spiders?
To understand how to deal with French house spiders, knowing what they are and why they might be entering your home is essential.
Description and Characteristics
French house spiders are medium-sized arachnids, typically brown or gray, with long legs and a somewhat oval-shaped body. Like most spiders, they have eight legs and multiple eyes, although their vision is not as sharp as other species like jumping spiders. Instead, they rely on vibrations and their webs to detect prey.
Common Habitats
These spiders are often found in human-made structures, preferring dark, quiet spaces where they can build their webs undisturbed. Basements, attics, and garages are prime locations for French house spiders since they offer shelter and a steady supply of prey.
Why They’re Common in Homes
French house spiders are drawn to homes for two primary reasons: food and shelter. Homes provide a stable environment where spiders thrive, especially during colder months when outdoor conditions become unfavorable. Their ability to adapt to indoor living makes them a recurring presence in many households.
Factors That Attract French House Spiders
Several factors influence why French house spiders are drawn to specific environments. Let’s explore these in detail.

Food Sources
French house spiders are predators, primarily feeding on insects and other tiny pests. Their webs are designed to trap unsuspecting prey, making areas with high insect activity especially appealing.
- Insects such as Prey: Flies, mosquitoes, and other minor bugs are the primary food sources for spiders. If your home has a noticeable insect population, it’s also likely to attract spiders.
- Reducing Insect Populations: Maintaining cleanliness, sealing food properly, and using bug repellents can help reduce the number of insects in your home, making it less attractive to spiders.
Shelter and Hiding Spots
Spiders thrive in environments that offer plenty of hiding spots. Cluttered spaces, cracks in walls, and even piles of laundry can serve as ideal shelters.
- Dark, Cluttered Spaces: Basements, attics, and storage rooms appeal to spiders because they’re dark and rarely disturbed.
- Decluttering Tips: Regularly cleaning and organizing these spaces can help discourage spiders from settling in. Additionally, sealing cracks and gaps in walls or windows can prevent spiders from entering in the first place.
Moisture
Spiders are attracted to damp environments because these areas also attract their prey. Bathrooms, kitchens, and basements are typical spider hotspots due to their higher humidity levels.
- Damp Areas: Leaky pipes, standing water, and poor ventilation can create the perfect conditions for spiders.
- Reducing Moisture: Fixing leaks, using dehumidifiers, and ensuring proper ventilation can go a long way in making your home less appealing to spiders.
Warmth
During colder months, spiders seek warm indoor spaces to escape the harsh outdoor conditions. They’re particularly active in the late summer and fall as they prepare for the winter.
- Seasonal Activity: You may notice more spiders indoors during the cooler months. Keeping your home well-sealed can prevent them from finding a way in.
Light Sources
While spiders aren’t directly attracted to light, the insects they prey on are. Outdoor lighting, for example, can draw flies and moths, which may, in turn, attract spiders.
- Managing Light Sources: Using yellow or sodium vapor lights outdoors can help reduce the number of insects and, by extension, the spiders that feed on them.
Scents and Odors
Certain scents, like citrus or peppermint, are known to repel spiders, while others may inadvertently attract them. Understanding these preferences can help you use scents strategically.
- Repelling Scents: Essential oils like peppermint, tea tree, and eucalyptus are natural spider deterrents. Spraying these around windows and doors can help keep spiders at bay.
Common French House Spider Species
Not all spiders in your home belong to the same species. Here are three common types of spiders you’re likely to encounter.
House Spider
These are the most common indoor spiders, known for their messy, irregular webs. They’re generally harmless and tend to stay out of sight.
Cellar Spider (Daddy-Long-Legs)
Often mistaken for a different type of spider, cellar spiders prefer damp, dark areas like basements and crawl spaces. Despite their long legs, they’re harmless to humans.
Wolf Spider
Unlike web-building spiders, wolf spiders are ground-dwellers that hunt their prey actively. They occasionally wander indoors but are more commonly found outdoors.
Spider TypeHabitatBehavior
House Spider Basements, corners Builds messy webs, passive hunter
Cellar Spider Damp areas, basements Prefers dark, moist environments
Wolf Spider Ground-level spaces Hunts prey actively, no webs
Preventing French House Spider Infestations
Here are some practical tips if you want to keep spiders out of your home.
Natural Remedies
Natural repellents like citrus peels, peppermint oil, and cedar wood can effectively deter spiders. These can be placed near windows, doors, and other entry points.
Cleaning Practices
Regularly vacuuming, dusting, and removing webs can help keep spiders at bay. Pay special attention to corners, ceilings, and other undisturbed areas.
Sealing Entry Points
Inspect your home for cracks, gaps, and other potential entry points. Seal them with caulk or weather stripping to prevent spiders from getting inside.
Benefits of Spiders in Your Home
While spiders might be unwelcome guests, they do provide some benefits. By feeding on insects, they act as natural pest controllers, reducing the number of flies, mosquitoes, and other bugs in your home. For this reason, some homeowners choose to tolerate their presence rather than eliminate them.
When to Seek Professional Help
If you’re dealing with a severe spider infestation or have concerns about specific species, it may be time to call in professional pest control services. Professionals can assess the situation and provide targeted solutions to keep your home spider-free.
Conclusion
French house spiders are fascinating creatures, but their presence in your home can be unsettling. By understanding what attracts them—whether it’s food, shelter, or moisture—you can take steps to minimize their presence. Small changes like decluttering, reducing moisture, and sealing cracks can make a big difference.
By staying proactive and following the tips outlined in this article, you can create a home environment that’s less inviting to spiders. And if you ever feel overwhelmed, don’t hesitate to seek professional help. After all, your peace of mind is worth it!
