Repel pesky spiders and ants with peppermint or cinnamon. I placed a cinnamon-infused twig broom on my porch because it always had spider webs. No more! And I put a few drops of peppermint oil on a several cotton balls (or squares) and placed them behind beds, bookcases, etc. to repel them indoors. No more webs found when I dust or vacuum.
