Ultrasonic rodent repelllant

[zipwize]

We had mice often. My wife bought a box of these and installed them all over the house and garage. She didn't tell me. I had a headache. The dog was restless. I woke up and went around the house discovering and pulling these out of the outlets so I could sleep. I found each one by the sound.

My wife got mad at me for disconnecting them and said I just pulled them to make her mad.
She said she couldn't hear them and that I couldn't possibly hear them either.

So how did I find them all? (dear).

I left the one's in the garage as I think they work. I see no mouse droppings since they were installed.

Hmm, thats interesting. Can you make a reverse engineering and lets know wat frequency, sweep maybe it is working, what does it have for speaker, how much power it is outputing, what power supply it has.

I think it must be lower at frequency of the 19-20KHz limit. Otherwise it is not possible to hear it or make you feel something or worse have a headache. May there is the secret. Make it close to the limit of human hearing point.

Hi, Anand,

Yes, it has been working fine ( was in a garage ) ... no beasts nor pets around for a while !!!

but sure it gives Headaches if you're not protected yourself ...

this is very well known in Africa where Europeans use their HiFi equipment as the final amplifier !!!

But think when you will stop it ... they'll be back after a moment.

so, poisonning or gunning rats ( my .22 cal. rifle works fine for that ...) is THE solution ...

Also think those beasts come when they smell something to eat ... and have somewhere to sleep.

Hi Alain,

Thanks for the confirmation that it works. This, alongwith your earlier pointers for the design is exactly what I was waiting for before I start building.

Hopefully, this should be the last time I've suffered this...

Regards,

Anand

For whatever its worth, I came across an almost identical thread started by somebody else on another forum. One of the posts pointed to this: http://www.ratbehavior.org/rathearing.htm and the general consensus was it wasnt going to be effective.

Any observations?

Hmmm, definitely this article is not helping you at all. But, if you are so eager to work on this project just give it a try. Experiment with diferent frequencies and see what happens. Maybe if you try to duplicate a predator's ultrasonic sound it would work. Just a thought.
