Utilizes a revolutionary infrared detecting system to sense the presence of a mouse, rat, or other rodent. Newly designed high-tech delivery system, including stainless steel kill pads housed in an aesthetic recycled plastic canister, now offers a 100% humane kill rate. Features a larger chamber that is perfect for larger rats and mice on-going infestations and commercial applications. Uses 4 "D" cell batteries (not included) which last approximately a year in stand-by power or provide 50 humane kills per set of batteries. Simply bait the Raticator Max trap with any dry food as an attractant to the rodent (dry pet food, trail mix, peanuts, etc.). Turn the main switch "ON". Green light indicates all systems are GO; when the rodent enters the Raticator Max, it will be humanely exterminated with a quick buy deadly shock. No mess and no poisons to endanger your pets or the environment. Flashing red light indicates when you have a catch. Turn the power switch to the "OFF" position, and just tip the unit over the appropriate disposal receptacle to remove the rodent. Re-bait and return the power switch to the "ON" position. Easy-to-use and reusable. Optional remote monitoring is available with the Raticator indicator. Not waterproof. Not for outdoor use when exposed to rain or snow.
