No one should EVER use pesticides, snap traps or those high-frequency devices. These things can harm other animals, especially those who might eat the mice or rats or stick their noses under cabinets, and it is possible they can hear the high frequency noise also. There is a "no-kill" trap that a friend gave me, which he got from a farm supply company. You just trap them and relocate them. Also, check the source of where they are coming in and plug it up. If anyone would like the name of the company where they can get the trap, let me know and I will find out and post it here. Shron [Posted in FML 7838]
