It is the duty of every person owning any premises in the city
on which there are growing any fruit, shade or forest trees, or shrubbery
of any kind, to keep the same free from caterpillars; and in the event
it is found that any fruit, shade or forest trees or shrubbery have
become infested with caterpillars, it is unlawful for the owner of
any such premises on which there are growing any such trees or shrubbery
to fail or neglect to promptly take and use such methods as may be
necessary to effectually destroy the caterpillars, or in lieu thereof,
destroy the trees or shrubbery. Any fruit, shade or forest trees or
shrubbery becoming infested with caterpillars is declared a public
nuisance.
