SBP 18 Pest Control: Flies


Flies are potential disease spreading vectors which are both serious problems to a farm’s sustainability.  The fact that many farm sites are located in close proximity to each other means fly control is also a community effort.

Flies 8Flies cannot be totally eliminated and as the number of animals increases on a farm site, so will the fly population.  The emergence of adult flies is the symptom of a larger problem.  Many people want to treat for the adult flies (ie. insecticide) but this does not manage the source of the fly problem, which is the ideal breeding conditions in the manure.






Flies 1The main issues that impact fly development are:
– poor water drainage on the farm site
– poor air circulation between barns and in barns
– infrequent manure removal
– excess water leakage from drinkers
– excess feed wastage
– inadequate manure storage facilities




Flies 11Flies like warm, high moisture environments that are high in organic material in order to reproduce.  The waste collection areas in most animal production facilities are ideally suited for fly reproduction.







Flies 9Keeping vegetation between barns and sheds mowed minimizes shelter areas for flies and allows for adequate air circulation.








Flies 10Mortality should be dealt with quickly by removing the carcasses from the CAZ and disposing of them.









Flies 2It is important to set up fly control mechanisms in barns, shed and feed mills/kitchens.  Use fly traps, bug zappers, sticky fly tape, insecticide bait traps, etc. in and around barns and other buildings on the farm site to help keep fly numbers at manageable levels.








Flies 3Not all pesticide products would be acceptable for use in farm yards and around livestock.  Therefore, it is criticial to read and follow each pesticide product label carefully before applying any product.
