Insecticides should be applied as soon as possible after departure of the birds, while house temperature is still warm. It
is still better to use insecticides active on both adults and larvae than on adults only. Then at beginning of production,
use an adulticide insecticide to kill as soon as possible early stages of flies developing in the house; this is the only
way to stop the life cycle of the fly. It is still better to prevent and act early than let the number of flies increase ,
resulting in an over population and greater difficulty in controlling them.
