Dryer sheets can help you repel cockroaches by trapping them on their surface. These
sheets contain linalool, a chemical that kills cockroaches. This ingredient is naturally found in
lavender and basil. You can also put them in picnic baskets and spread them out in open
spaces to deter cockroaches. Other options include wrapping them around clothing or placing
them where cockroaches are active. The best method is to lay multiple sheets in one area,
because this technique will widen the impact radius of the scent.
