Cleaning the
barn cheapest
control of flies
A good old pressure washer
may be the cheapest, most
effective control of troublesome
flies in a swine operation,
University of Guelph
researchers say.
Wayne Bennett and Gordon
Surgconer tested several fly -
control methods including
biological controls like parastic
wasps, fly strips and baited -jug
fly traps and found the most
economical control is still a
clean barn.
Testing the wasps, which
attack the pupal stage of the fly,
they found that high initial cost
($44.15 per 15,000) and the fact
the wasps do not reproduce on
their own, led to a high cost of
$244.50 per room in a 17 -week
test in a weaner room and two
grower -finisher rooms. The
success rate was only 38.6 per
cent in the weaning room and
27.2 per cent in the two grower -
finisher rooms.
Fly strips didn't work well
because of the amount of dust.
Baited -jug traps provided good
control, 57 per cent in the
smaller weaning room, but it
took three traps in the larger
grower -finisher rooms to bring
effective control.
Still, good manure manage-
ment by pressure washing
manure out of the comers of
rooms and around the feed
bunkers had the best results, a
64 per cent reduction. The
cleaning should be done at least
once every 10 days to remove
the food needed by developing
flies. Maggots and developing
pupae can't survive in liquid
manure if they're washed into
the manure pit. Based on a $10
per hour wage, the researchers
estimated a cost of $5 per room
per wcek.0
