Permethrin is a synthetic version of pyrethrins.
Pyrethrins have long been known for rapid knockdown of
insects. Although permethrin is more stable than pyrethrins, it
is still degraded by the ultraviolet rays of the sun. This results in a
relatively short residual life in the presence of sunlight. When protected
from the sun, permethrin will provide residual/long lasting activity.
