Hedeoma pulegioides). This herb can be found in two major forms American
Pennyroyal plants and Oil of
Pennyroyal. You can buy the plant at most nurseries. To repel spiders with the plant dry some leaves and place crumbled up leaves where the spiders congregate. Oil of
pennyroyal can be found at most heath food stores and can be placed on cotton balls where the spiders live. Once you place the
pennyroyal to spiders will leave, in a hurry! Don't buy essence of
pennyroyal as this form is highly
concentrated and can be very dangerous for
pregnant women.
