If resistance develops in the fly to the larvicide this will be transferred to the
parasitic wasp maggot and the wasp will survive.
Each farm is unique and we will develop the best fly management program for each
farm, but as a guide, in a single age shed of 8000 layers with moderate fly levels
you could use :
-
1 bag of wasps every 2 weeks for 3 months
- Then monthly depending on the
challenge level
In broiler breeders a similar calculation can be made.
The wasps are very small and will remain at the level of the manure where their
food supply is plentiful. They do not attack humans.
