Pest-A-Cator Plug-In Electronic Pest Repeller For Rodents 1 pkPest A Cator 2000 is not an ultrasonic product. The electrical wiring inside your home already has an existing field surrounding it. When Pest A Cator is plugged in, it pulses this field. It doesn't really add to or take away from the field - just pulses it. Rodents like to live and nest inside the walls. They feel the pulse and don't like it, so it drives them out. This means that if there is an infestation of rodents, the consumer will see more during the first four weeks or so, because the Pest A Cator is helping drive them out of the walls. We recommend using traps of your choice the first few weeks to help clean up the initial problem. Additional units are recommended for larger single level areas or multiple story structures.Direct plug-in feature is user friendlyCompletely maintenance-freeWorks with electrical wiring in your homeNot a trap that requires emptying dead or dying animalsJust plug it into any 110V indoor outlet and the patented pulse technology signal is sent throughout your homeSafe to use around children and household pets and pest a cator products may help in reducing your monthly exterminator costSpecifically designed for smaller homes, apartments, condominiums and mobile homesREPEL PEST ELEC2000SQFTBrand Name: Pest-A-CatorPower Source: Plug-InProduct Type: Electronic Pest RepellerPest Type: RodentsNumber in Package: 1 pkIndoor or Outdoor: IndoorTreatment Coverage Area: 2000 sq ftMotion-Activated: No
