Households are being urged to leave cinnamon sticks by their windowsills this September, as the spice becomes extremely beneficial for homes during this month. The advice follows the peak of spider mating season, when male spiders emerge from their hideaways to seek female partners within households.
A social media profile recently recommended three products that can individually address the issue during mating season. In a TikTok clip, Jeff and Lauren advised: "In case your mum didn't tell you put cinnamon, star anise and cloves in your windowsills and doorways to keep bugs and spiders out!"
Why spices repel spiders
It is well established that powerfully scented spices such as cinnamon, star anise and cloves function as natural spider repellents. Spiders detest cinnamon because it produces a powerful compound called cinnamaldehyde, which irritates the sensory organs located on their legs.
The powerful fragrance also interferes with their capacity to detect environmental signals, complicating their ability to locate prey or find their way. Star anise operates similarly, as its scent derives from trans-anethole, a potent chemical compound. Meanwhile, clove possesses an equally intense and sharp aroma that triggers discomfort, ultimately compelling the spider to retreat and relocate elsewhere.
How to apply the spices
To repel spiders effectively, target entry points by placing whole cinnamon sticks, cloves and pieces of star anise directly on windowsills, window tracks and door thresholds. Spiders use tiny scent receptors to navigate, so when the heavy wall of spice blocks this gap, they tend to avoid the area.
It is important to refresh the spices regularly, replacing them once the strong aroma fades to keep the deterrent effective. Additionally, sealing tiny cracks with silicone or caulk on walls, skirting boards, vents and around windows and doors can help block potential entry points. Fitting door sweeps and window screens will also help ward off unwanted creepy crawlies.
However, certain repellents and essential oils used to deter spiders can prove toxic if consumed by household pets such as cats and dogs. Always ensure any diluted mixtures are used carefully and kept well out of reach of animals.
