update, we are now in 50 different hardware stores and getting phone calls daily from individuals from all over the US from our web site. Pack rat season is here now. I trapped over 40 rats this summer. I didn't even know that I had a problem until I found on had chewed on a trunk of one of my plumeria.
Some sonic devices do work but not all and it depends on what you are using them for. The ones we tested did nothing to the pack rats. Our devices are only for car engines.That is the only thing we presently test for. We also have a device that keeps the pack rats away from pool and jacuzzi wires and one for Bar B Q's. For some reason the pack rats like to nest in the Bar B Q's.
