Prohibition of mosquito breeding in collection of water

(1) No person or local authority shall— (a) have, keep, or maintain within any local area any collection of standing or flowing water in which mosquitoes breed or are likely to breed, or (b) cause, permit or suffer any water within such area 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:—Troughs used for cattle and in frequent use shall not, until the contrary is proved, be deemed to be collections of water in which mosquitoes breed or are likely to breed. (2) The natural presence of mosquito larva in any standing or flowing water shall be evidence that mosquitoes are breeding in such water.
