Ultrasonic Piezo for animals

[haw]

I have just found an old thread about a project
for produce ultrasonic to annoy the animals.

What is the best piezo supertweeter for that kind of job?
some of them can arrive up to 100khz?

Thanks.

I was reading thru the thread too... was wondering what frequency got rid of ants!

I would like to make something too.

There are ants in New York? I thought they were a warm climate beastie.

Dunno, the one consumer home product I've seen that tries to be an all-in-one pest control sweeps from ~30-65k at up to 120 dB, though I've read that it takes >100 k for some insects. Dogs, cats aren't bothered, but no rodent pets allowed (gerbils, hampsters, etc..

AFAIK, there's been no sub-arctic ants since prehistoric times, but then there's areas of the tropics today without them too, but otherwise they blanket much of the world.

I liked the project because it quite easy to change the frequency, for use with different animals/insects.
do you know already what piezo use?
