Laundry sheets, known for their scent and softening properties, are frequently claimed to repel spiders and insects. Key ingredients such as linalool have insect-repellent properties but evidence for spider repelling is anecdotal. Historical use of scent-based pest deterrents supports this practice, but spider sensory biology limits effectiveness. Practical use includes placing sheets strategically and combining with other methods. Consider potential risks, and rely on multiple approaches for effective control.
