Efficient and effective, the Eazyzap plug-in pest repeller is an eco-friendly way to keep annoying pests such as insects, small rodents and bugs at bay. By flooding an area with human-safe ultrasonic and electromagnetic wave patterns, the Eazyzap makes a large area highly uncomfortable for pests, encouraging them to move away from the source. The repeller is completely safe too, with no effect on humans or pets - there's no chemicals, no traps and no mess. Simply plug in the repeller in the affected area and over time, the pests will find a new home. Using only 3. 5W, the repeller is highly efficient and covers an impressive 200 square metres, so you can cover a wide area without excessive running costs. And as you get two units, you've got plenty of coverage for a typical family home or wherever effective pest control is required.
