All artificial containers and water-holding devices so placed that they may hold water for a period of five days or longer, unless such containers or devices are tightly covered or screened to prevent the entry of mosquitoes, constitute a public nuisance. No person shall maintain on his or her premises unscreened or un covered containers or other water-holding devices under conditions that permit mosquito larvae or pupae to develop. All uncovered or unscreened containers or other water-holding devices shall be completely drained or the water therein changed at intervals of not more than five days between April 1 and October 25, or effective insecticides must be applied to all exposed water surfaces at intervals of not more than five days during that period.
