Each backend the calf pens are full of flies, the cows
walk from the fields with few flies on them but as soon
as they enter the building they’re covered. There
are pour on products for the cows, big fans or insecticide
sprays for the parlour and I’ve recently seen a
shower type unit that creates a wall of water at the
parlour entrance preventing flies getting in.
The fact remains that, however many you kill, the flies
are still there in their thousands. Where do they come
from?
As vets we’ve advised small animal clients on
their flea treatments for many years. We know that treating
the animal itself with Spot ons or sprays does little
to control the problem in the long run. 85% of the flea
population is in the form of eggs and larvae and in
the carpets and furniture. Unless you control them,
the fleas will carry on maturing and infesting the pets.
It’s the same with flies on the farm! The eggs
and larvae are in calf pen beds and muck heaps. Organic
farmers are now using parasitic wasps that eat the maggots
to reduce the fly population.
Another way is using Neporex, which comes as prills
that you sprinkle every six weeks around the edges of
bedded areas and over muck heaps. Both methods stop
the maggots developing into flies. Spy and Oxyfly are
long acting fly killers that you spray or paint onto
the walls of a building.
We think that using these products in combination will
improve life for man and beast in the backend. We’re
carrying a small amount of these products in stock for
you to try.
