As the host animal enters
the trap, there is a significant change in light intensity
sufficient to cause the Buffalo Flies to leave their host and 'fly
to a more lighted place'. You can see this effect in a herd when a
cow goes to lie down or when two cows come close to each other. All
the flies on the affected area of the animal where the light changes
to shadow will suddenly fly off.
Once airborne in
the tunnel they are attracted to the brighter light coming in
through the slits and will fly towards that light-source. They are
then caught in the capture chambers along either side of the tunnel where they quickly expire due to exhaustion.
Buffalo Fly Trap was developed by CSIRO and tested extensively by
the Department of Primary Industries and Fisheries. In its original
form the invention was definitely worthwhile but our
in-house research and development team have managed to improve the
effectiveness of the trap as well as tackling the four main problems
with the original design to
produce a unit that is considerably more advanced and effective in
************* Our TEN
PERCENT IMPROVEMENT in Capture Rate: *************
The statistics on the original CSIRO design
indicated a capture rate of 60 to 80 percent. So, a unit
was constructed according to their specifications and tested extensively. Our
statistics on their design showed a 65 percent decrease in fly numbers after ten
days, which is a decrease of two thirds.
Then, after extensive research and development
by our own team, it was discovered that a few subtle changes to the
shape and size of the light-slits and the width of the tunnel brought
about a significant increase in the capture rate to about 75 percent or
three quarters of fly volume after the same ten day period:
a TEN PERCENT IMPROVEMENT over the original design.
There was an initial reluctance for cattle to go through the tunnel.
To improve this situation we added a pair of
panels dubbed 'approach wings' on either end that offers a more approachable
environment which the cattle are probably more used to and which act
to guide them into and through the trap more readily. During testing
we observed several cattle who approached the trap but stopped
between the wings as though they were unsure about going through. As
other cattle approached them from behind it became evident that they
had to decide to either turn around within the wings and 'go back'
or 'go through'. Most opted to go through the tunnel. And
observing this, those approaching from behind often followed without
We saw this as a major improvement over the
original structure where the cattle could simply walk to the side
and avoid the decision to enter or turn back.
N.B. The approach wings are not meant to be an impenetrable fence. They only act to guide the animals in a non-threatening way. They also act to stabilise
the unit from wind or other forces that might dislodge or move it.
The original unit was too heavy to be moved by one man.
We have replaced the heavy ply sides and top
with Poly Plastic which is just as effective and much lighter. We
have also improved the shape and weight of the capture chambers. The
end result is a unit that can be lifted onto a ute or truck for
relocation by one man without disassembly.
3. Flies that entered the trap were able to escape by the same route.
The original square trap had a long slit that admitted the flies into the trap as they rose upward towards a stronger light source. But flies were then able to drop down and go back out of the trap and many were lost as a result.
The "V" shaped trap we have developed does not allow the flies to find their way back out of the trap. This ensures a far greater capture rate than previously recorded.
4. The original design did not allow emptying.
We have added a 'tear-off' velcro tab that allows the operator to quickly and easily empty the build-up of expired flies.
to Set up and Implement your Buffalo Fly Trap
Choose a place where the cattle will pass
regularly. This may be a gateway or path to water or supplement
feed. In some cases it may be necessary to fence off a water-point
so that in order to gain access, all cattle must pass through a
gateway and thus through the trap.
(N.B. This form of trap is not suitable for
paddocks where cattle can drink from a creek or river as there is no
way to get them to pass through it, unless there is a well used
Set up the tunnel in place. Cattle may be hesitant to enter initially but eventually one will scamper through and the rest will quickly follow.
Once the cattle are used to traversing the
trap you will note a considerable drop in Buffalo Fly numbers to
such a degree that they will no longer be considered a significant
menace. The number of flies will vary according to how regularly the cattle pass through the trap.
