  • In kitchen cabinets
  • Where food is stored

Do bay leaves keep roaches away? Well, as with any natural remedy that answer can be somewhat contentious and can depend on numerous factors. But in our experience, Yes – bay leaves do keep roaches away.

Bay leaves contain compounds that are known to repel insects such as eucalyptol.

Simply place fresh bay leaves around the kitchen, behind appliances, near entry points and any other areas where cockroaches are likely to hang out.
