Does Cedar Keep Spiders Away? It’s a common belief that cedar repels spiders, and many homeowners swear by cedar chips, cedar oil, and cedar-lined closets to keep these eight-legged creatures at bay. But is there any scientific truth behind this age-old remedy, or is it just an old wives’ tale? Let’s delve into the science and explore the effectiveness of cedar against spiders.
The Allure of Cedar: Understanding its Repellent Properties
Cedar, particularly Eastern Red Cedar (Juniperus virginiana), contains natural oils and compounds, specifically plicatic acid, that are known to repel certain insects, most notably moths. This is why cedar chests have been a popular storage solution for woolens for generations. The strong, aromatic scent we associate with cedar is a direct result of these oils. But does this same repellent effect apply to spiders?
Does Cedar Repel All Spiders? The Nuances of Arachnid Control
While cedar may deter some insects, its effectiveness against spiders is less clear-cut. Spiders aren’t insects; they’re arachnids, and they react differently to various repellents. Research on cedar’s impact on spiders is limited, and anecdotal evidence provides a mixed bag of results. Some people report success in deterring spiders with cedar, while others see no noticeable difference.
Types of Spiders and Their Response to Cedar
Different spider species exhibit varying sensitivities to cedar. Some, like the common house spider, might be somewhat deterred by the scent, while others, such as the more persistent brown recluse, may be less affected. The concentration of cedar oil also plays a role; higher concentrations may be more effective, but not always practical or safe for household use.
Practical Applications of Cedar for Spider Control: Tips and Techniques
If you’re considering using cedar to deter spiders, here are a few practical applications:
- Cedar Chips or Mulch: Placing cedar chips around the foundation of your home may help create a barrier, though its effectiveness is debated.
- Cedar Oil: Diluted cedar oil can be sprayed in areas where spiders tend to congregate. However, be mindful of the concentration and potential impact on pets or children.
- Cedar-Lined Closets: While primarily used for moth control, the scent of cedar in closets may offer some deterrent effect against spiders.
- Cedar Blocks or Balls: Placing cedar blocks or balls in storage areas or drawers may offer some protection against spider infestations.
Combining Cedar with Other Spider Control Methods
For optimal spider control, it’s often best to combine cedar with other proven methods. These include:
- Regular Cleaning: Removing webs and eliminating clutter reduces spider hiding places.
- Sealing Cracks and Crevices: Prevent spiders from entering your home by sealing any gaps or openings.
- Sticky Traps: Strategically placed sticky traps can capture spiders that wander indoors.
Expert Insights: What the Professionals Say
“While cedar’s repellent properties are well-documented for certain insects, its efficacy against spiders is less definitive,” says Dr. Emily Carter, entomologist at the University of California, Berkeley. “More research is needed to fully understand the impact of cedar on various spider species.”
“Homeowners should view cedar as one component of a multi-faceted approach to spider control,” adds pest control specialist, John Miller. “Combining cedar with other preventative measures is key to effectively managing spider populations.”
Conclusion: Does Cedar Keep Spiders Away?
So, does cedar keep spiders away? The answer isn’t a simple yes or no. While cedar possesses repellent qualities that may deter some spiders, it’s not a foolproof solution. Its effectiveness varies depending on the spider species, the concentration of cedar oil, and other environmental factors. For best results, incorporate cedar as part of a comprehensive spider control strategy that includes regular cleaning, sealing entry points, and other preventative measures. This multi-pronged approach will offer the most robust defense against these often unwelcome guests.
