Do I need a DX610 Electronic Pest Repeller for each floor and basement?

Yes. It is recommended. Though the DX610 electronic mouse, rat, rodent repeller has a higher frequency (45,000 HZ) than most other mice repellers on the market, we do recommend that you plug one into each floor for maximum performance.

When you discover that you have a rodent problem, it is critical that you act quickly to drive them out.

If you have them on just one floor, you run the risk of driving them to a floor without protection of the DX610 repeller.  By having our repellers on each floor, garage, attic, and basement, there will be no where for the rodents to hide, and they are forced to leave to get away from the sound.
