Does anyone know how those electronic pest repellents are supposed to
work? My grandparents have two different ones at their house to repel
ants. The one in the kitchen certainly doesn't do a thing to repel the
ants but it sure makes me want to leave. That thing keeps making
annoying, sort of high-pitched sounds. No one else hears it except for
me. I'm wondering if it's making a frequency that only people under 30
can hear. I ended up having to unplug it because it was so annoying
and everyone thought I was crazy. So it makes me wonder how those
things are supposed to keep bugs away. I didn't think people were
supposed to be able to hear them.
Well, if you had ants in the kitchen and the buzzing made YOU
leave the kitchen and go into another room, you weren't around
the ants anymore....
That's the only explanation I can come up with to support the
I haven't found anyone supporting the product other than the
people who manufacture them and the people who sell them....
Around here we have scorpions who come into the house and
eat all the ants and crickets. NOTHING repels scorpions...... You
just gotta learn to live in your environment... :>))))

They are, without exception, completely worthless for their advertised
They send out sound at frequencies that are suppose to be above the range of
human hearing. As people age usually the hearing range decreases. It tops
out around 20,000 Hz for most young people. Some can hear higher and you may
be one of them. The older CRT TV sets put out a very high pitch sound. Can
you hear it ? It is around 15,700 hz. The crt computer monitors are about
double that at 31,500 . Unlikely anyone will hear that. Dogs can hear
higher frequencies and that is how the silent dog whistles work. Other
animals can hear higher frequencies yet.
They are suppose to make enough noise to make the animals leave the area
just as loud noise would make you want to leave.
There are portable units you hook on your belt to keep the mosquitoes away.
Not sure about them,but I have not seen the mice stay away.
Send the doubters here-
These folks are selling security systems based on frequencies only
young folks can hear.
[on the critter chasers, my parents swear by theirs. I've tried one
for mosquitoes and don't think it made a difference]
About 15 years ago a local inventor came out with a mosquito chaser that made a
buzzing sound that was supposed to sound like a dragon fly. Apparently dragon
flies eat a lot of mosquitoes. Didn't work but he made about $50 off me and my
