The methods of treatment of any collection of water for the purpose of preventing the breeding of mosquitoes must be approved by the director, the city health officer, or the city environmental health officer or their duly authorized representatives, and may be one or more of the following:
(1) Screening with wire netting of at least 16 meshes to the inch one way or any other material that will effectually prevent the ingress or egress of mosquitoes.
(2) Complete emptying every seven days of unscreened containers together with their thorough drying or cleaning.
(3) Using an approved larvicide.
(4) Covering completely the surface of the water with kerosene, petroleum, or paraffin oil once every seven days.
(5) Cleaning and keeping sufficiently free of vegetable growth and other obstructions, and stocking with mosquito-destroying fish; absence of half-grown mosquito larvae is evidence of compliance with the measure.
(6) Filling or draining to the satisfaction of the director, the city health officer, or the city environmental health officer, or their duly authorized representatives.
(7) Proper disposal of tin cans, tin boxes, broken or empty bottles, and similar articles likely to hold water. (Code 1941, Art. 86-39; Ord. 27697)
