Maggots Granular Larvicide is specifically formulated to eliminate and control fly larvae. As a highly efficient larvicide, it attacks the maggot to prevent it from developing into a fly. It can be sprinkled on slurry or diluted with water and sprayed directly onto problem areas. Expect to see results approximately two weeks after the first application.   
 
This product is perfect for controlling flies in poultry houses, pig fattening units, pig breeding units, dairy and calf units, sheep and goat units, horse stables, and waste management sites.
