Placerville Municipal Code Ch. 6 Mosquito Control

It shall be unlawful to maintain or permit, within the limits of the city, any collection of standing water in which mosquitoes breed or are likely to breed, unless the collection of water is treated so as effectually to prevent such breeding. Any collection of water considered by this section shall be held to be those contained in ditches, pools, ponds, excavations, holes, depressions, open cesspools, privy vaults, fountains, cisterns, tanks, shallow wells, barrels, troughs (except horse troughs in frequent use), urns, cans, boxes, bottles, tubs, buckets, defective house roof gutters, tanks of flush closets or other similar water containers. (Ord. 757, 6-15-1953)

The method of treatment of any collection of water, such as specified in this section, directed toward the prevention of breeding of mosquitoes shall be approved by the accredited health officer and may be any one or more of the following:

(A) Screening with wire netting of at least sixteen (16) meshes to the inch each way or with any other material which will effectually prevent the ingress or egress of mosquitoes.

(B) Complete emptying every seven (7) days of unscreened containers together with their thorough drying or cleaning.

(C) Using a larvicide approved and applied under the direction of the health officer.

(D) Covering completely the surface of the water with kerosene, petroleum, or paraffin oil once every seven (7) days.

(E) Cleaning and keeping sufficiently free of vegetable growth and other obstructions, and stocking with mosquito destroying fish.

(F) Filling or draining to the satisfaction of the health officer or his accredited representative.

(G) Proper disposal by removal or destruction of tin cans, tin boxes, broken or empty bottles, and similar articles likely to hold water. (Ord. 757, 6-15-1953)

The natural presence of mosquito larvae in standing or running water shall be evidence that mosquitoes are breeding there, and failure to prevent such breeding within three (3) days after notice by the health officer or his authorized representative, shall be deemed a violation of this chapter. (Ord. 757, 6-15-1953)

Should the person responsible for conditions giving rise to the breeding of mosquitoes fail or refuse to take necessary measures to prevent the same, within three (3) days after due notice has been given to them, the health officer is hereby authorized to do so, and all necessary cost incurred by him for this purpose shall be a charge against the property owner or other person offending as the case may be. (Ord. 757, 6-15-1953)

For the purpose of enforcing the provisions of this chapter, the health officer may at all reasonable times enter upon any premises within his jurisdiction; and any person charged with any of the duties imposed by this chapter failing within the time designated by this chapter or within the time stated in the notice of the health officer, as the case maybe, to perform such duties, or to carry out the necessary measures to the satisfaction of the health officer, shall be deemed guilty of a separate violation of this chapter. (Ord. 757, 6-15-1953)
