Can anyone comment on the success (or otherwise) of strategies to prevent

Is there a DIY solution to this problem?

The ultrasonic devices I have seen on the internet range in price from about
£16 to approx £45 anyone care to pass on their experiences with these
devices? is price related to efficiency? Is it possible to build one of
these devices?
