I've used an ultrasound emitter to deter rats from my kitchen with great success. The devices emit a very high frequency sound that is above the hearing range of humans and most pets, but other animals such as rats, mice, squirrels and bats can hear it and avoid it because they are either confused or irritated by it. While the devices are effective deterrents, they do have limitations. Because of the high frequency, the sound bounces off solid surfaces such as walls, cupboard doors, etc., and doesn't penetrate through. So it wouldn't penetrate into the space between your double walls. You mention 'plugging the holes' which suggests the holes are on the outside of the structure. By placing ultrasound devices on the exterior of the structure, especially near the holes, you would create an ultrasound barrier that would keep rodents away. The effective range for most devices is about 25m.

We've tried plugging the holes with hardwire cloth and copper mesh, but the squirrels just pull it out and use it as nesting material. The building has double walls with a gap in between, perfect for stuffing with apples and raising squirrel babies. A member of our maintenance crew brought in information about an ultrasound emitter that acts as a repellent. (This one is called "YardGard.") Does anyone have any experiences with these kind of devices and whether they work? Thanks, Sam Samantha Richert, Curator Klondike Gold Rush NHP P.O.
