No person

shall, on any land owned by him or in his possession,—

1. (a) have, keep or maintain any collection of standing or flowing water in which mosquitoes breed or are likely to breed, or
2. (b) cause, permit or suffer any water on such land to form a collection in which mosquitoes breed or are likely to breed, unless such collection has been so treated as effectively to prevent such breeding. Explanation I.— Troughs used for cattle and in frequent use shall not, until the contrary is proved, be deemed to be collection of water in which mosquitoes breed or are likely to breed. Explanation II.— The natural presence of mosquito larvae in any standing or flowing water shall be evidence that mosquitoes are breeding in such water.]
