Repels mice and spiders, but not very long.
Mice definitely do Not like this.  After i sprayed this on or near to mice, have seen them immediately do a big jump away.  Hoever, the repellent effect decreases to nearly nothing after 10 or so hours.  This correlates closely with the effect on my nose.  Makes my nose run though am always spraying away from me--the oil propagates through air upwards by evaporation.  That wears off mostly after 8 hours.
