The Rat Zapper Rat Tale makes the Rat Zapper even more effective in those hard to reach nooks and crannies rodents love so much. The Rat Tale, with its 12-foot-long extension, plugs into your Rat Zapper, making it easy to monitor in attics, in sub-flooring, behind furniture and in other difficult to reach places. Its two blinking red eyes tell you when to empty your Rat Zapper. For indoor use only.
