Drilled a few holes in which I
squirted a few drops of oil of pennyroyal.. End of story.. I place oil
of pennyroyal about my foundation every so often, Works and is not to
toxic. DO NOT TAKE IN INTERNALLY. Smell makes em consider a nicer
place to live.

Oil of Pennyroyal is used to cause abortion!
I would not have it around a pregnant woman in any form....internally or
otherwise.
