Seen plenty of different types of what loosely could be called
non-traditional/ non-substance, or technologically-based rodent
killers or deterrants, but do any actually work and what, if any, is
the evidence??
I undestand from what I read that the claims of some of those
promoting such products is that all small animal pests from
cockroaches to rats will be destroyed or be forced to vacate the
premises because of an absolute intolerance for either the highpitched
sound waves produced, the vibrating elecrtical field or whatever
else was claimed as the key to the claims made.
Again what is the truth and if positive what is the evidence
I cannot show you web-based research on this, but I have personal
experience with the alleged "sonic" mice repellents. They do not
work. We have an outbuilding next to a field in which we located four
of the sonic devices a few years back. Each fall the mice begin to
head indoors, and each fall we catch a dozen or so in the traditional
traps we set up for insurance. I heard one neighbor gentleman say, "I
used those sonic mouse chasers, and it just provides music for the
mice to dance to." I think he is right.
Now as a matter of purely empirical study, I suppose one could argue
that if we did not use the sonic ?repellers? we'd have MORE than a
dozen caught in the traps, but that seems doubtful. So why do we keep
them plugged in at all? Because they were so darned expensive I am
not going to just throw them out!
Stay with traps baited with bread and butter.
an electronics freak and friend of mine once demonstrated his
ultrasonic speaker by aiming it at a cat 25 yards away. The high
frequencies have a very specific direction, so he had to actually aim
at the animal (that didn't see him). In an instant (upon aiming and
flipping the switch) it took off.
So while the animals hear the deafening noise at frequencies we can't
hear, I doubt whether it would be very effective if you don't have a
way of aiming the soundwaves directly at the animal.
.. and thanks for the feedback and website reference which I read Does
not look like I need to pursue this method any further. I am now
considering something a little less technological based with fur and a
tail.
