(Ordinance 91, sec. 6, adopted 8/12/40; 1972 Code, sec. 16-5)
The city shall have full power to abate all nuisances within the city as are hereinafter set out, and as may be declared to be nuisances from time to time, and shall prosecute same in the courts of this state and city as provided by the constitution and laws of this state pertaining to same.
(Ordinance 91, sec. 1, adopted 8/12/40; 1972 Code, sec. 16-6)
(a) 
The cocoons (otherwise called bags) of all members of the genus Thyridopteryx (commonly known as bagworms), and the webs (otherwise called nests) of all members of the genus Malacosoma of the family Lasiocampadiae (commonly called tent caterpillars) and of all members of the genus Hyphantria of the family Arctiidae (commonly called webworms) are hereby declared to be nuisances and are prohibited within the city limits and within five thousand (5,000) feet thereof.
(b) 
The person having the right to possession of any land within the city, or outside the city and within five thousand (5,000) feet of the city limits, shall keep such property free of the cocoons, bags, webs and nests prohibited in subsection (a) hereof, and shall destroy such cocoons, bags, webs and nests, and all larvae therein.
(c) 
Every person who removes any cocoon, bag, web or nest prohibited in subsection (a) hereof, or who removes or cuts down any tree or other plant to which any such cocoon, bag, web or nest is attached, shall immediately destroy all larvae therein, and shall not in any manner dispose of such cocoon, bag, web, nest, tree or plant until all such larvae have been destroyed. Any person or official required or authorized by this section to destroy cocoons, bags, webs and nests may, at his option, in lieu thereof, destroy the bagworms, tent caterpillars and webworms by spraying with insecticide generally recognized as suitable for such purpose; and if such destruction is successfully accomplished it shall be deemed sufficient compliance with this section, without actual destruction of the cocoons, bags, webs and nests.

(e) 
Any person violating this section shall be deemed guilty of a misdemeanor and each day of failure to comply shall be considered a separate offense.
(f) 
Within the meaning of this section the person having the right to possession of land is the owner; or if the land is leased or rented, the lessee or tenant, and, if the property is unoccupied, any agent having authority to lease, rent, sell, manage, or take care of the land.
(g) 
As an additional means of enforcing this section, and regardless of whether or not any person is convicted of a misdemeanor for its violation, the superintendent of parks is authorized to destroy cocoons, bags, webs and nests existing in violation of this section (including, if reasonably necessary, the destruction of trees and other plants), and to have the expense thereof made a lien on the land. In acting under this subsection the superintendent of parks and other city officials, except the superintendent of sanitation, shall follow the procedure prescribed in sections 7.02.003 and 7.02.005 of the Code of Ordinances.
