Where it is not practicable to re-move manure, it may be kept cov-ered in a dark place, which discour-ages the visitation and breeding offlies, and in addition should be care-fully screened. Larvae may be de-stroyed. The best results are ob-tained by the use of borax (sodium borate) and calcined colemanite (crude calcium borate).^ Both sub-stances possess a marked larvacidal action and appear to exert no per-manent injury on bacteria. In order to kill fly eggs and maggots, pound borax or pound calcined colemanite to every 10 cu. ft.(8 bushels) of manure immediately on its removal from the barn.
