Pest-A-Cator operates continuously and complies with applicable FCC rules (this device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and, (2) this device must accept any interference received, including interference that may cause undesired operation). Within days, you may see an increase in activity as Pest-A-Cator begins working. Just plug it in. Pest-A-Cator's patented pulse (electro-magnetic) technology was designed to connect through the neutral wire of a standard electrical outlet, and to send a pulsing signal throughout the wiring of your home (or other structure). This silent pulse is intended to annoy rodents and may help with problems behind walls, floors and ceilings where rodents typically nest. Similar to any other pest management techniques, no one method is completely effective, and a program of integrated management involving a variety of techniques and practices is most likely to provide the desired results. Uniquely humane: Pest-A-Cator may help with rodent problems in the home, office, restaurant, health care facility or other enclosed structure with standard electrical wiring within 2-4 weeks. Manual trapping methods (such as Pest-A-Cator live rodent trap) can be used to aid with initial clean up. For real problem areas, try plugging a Pest-A-Cator Plus unit into an unobstructed outlet in the infested area. Not a chemical: Pest-A-Cator can be one alternative to harmful or hazardous chemicals and may help in reducing your dependence on regular, expensive visits from the exterminator.
