It breaks the horn fly life cycle by preventing pupae from developing into biting adult flies – pupae that would otherwise survive the winter, leading to prolific spring fly populations. The European Hornet (Vespa Crabro) is much bigger than the Common or German (European) wasp. The life cycle of the horn fly takes place only in fresh cattle manure. Although considered much more aggressive than the common or German wasp, in our experience this is not the case. Horn fly presence or absence is temperature dependent, while abundance is influenced by humidity and precipitation. While you will never eliminate all flies on cattle, maintaining a fly control program will help limit populations to less than 200 flies per animal, the economic threshold established for horn flies on beef cattle.
