Do Sonic Pest Chasers work?

Do Ultrasonic Pest Control devices really work for mice and rats? When we moved into our current house there apparently was a bad problem with rats that we only found out about by one dying in the walls. We have since gotten rid of them but I have this fear that they will find a way back in. So, if I set a couple of these devices up in our crawlspace and attic would that work to deter them? And will they really not bother my dogs?

I had one, it was a cheap one, so don't accept this as your only datapoint. It never bothered by dog, but it never seemed to bother the mice either.

The Federal Trade Commission is dubious about these devices.

If I was a wandering mouse rousted from my digs and I passed by an apartment with a screeching noise I might move on to the next appartment.

If someone turned on the noise in my own mouse house I would just deal with it.

We had a couple set up in the kitchen and we still got ants in the summer and had mice in the winter.

They didn't bother the dogs though.

Never tried the Ultrasonic Pest Controls because somebody told me that regular old Mothballs worked great. I tried it, they did. They need replenishing about once a year, but cheap and effective (at least for me).

I use rat poison.

My sister tried the ultrasonic against flying squirrels (northern Wisconsin) and it did not work.

You could get a pet ferret or weasel. They eat rats.

Ultrasonic devices are crap. You need a cat.

You'd be much better off inspecting your house for critter-entrances and closing them off, and looking around your property for critter-attractive-nuisances such as garbage and critter-motels such as gaps under garages.

The device worked for me. My ferrets never killed a thing.

It's kind of creepy how many "help! mice/rats!" askme posts are appearing lately. Do you think they could really be aliens?

I agree with dhartung. The best method is always to make sure they cant get in in the first place. Problem solved.
