In tests at Savannah, Georgia, during 1950 with technical BHC (12 per cent gamma isomer), lindane, dieldrin and chlordan, best results were obtained with technical BHC for controlling fly breeding present in the bottom sludge of garbage cans at the time of treatment. Chlordan was the least effective. In 1951 tests, PDB crystals were more effective than technical BHC. No material tested either year was effective in controlling fly breeding in garbage cans beyond 2 weeks after treatment. All materials tested appeared to be more effective against the more common blow flies than against house flies.

Several common species of flies, including house flies, emerged sporadically from garbage cans throughout the winter of 1950–51, during which there were numerous cold spells with minimum temperatures as low as 15°F. Emergence frequently occurred on days when the minimum temperatures were well below freezing, 21°F. being the lowest.
