This ultrasonic rodent chaser uses advanced dual-speaker technology to emit sound waves at frequencies between 22-35KHz and 25KHz, effectively deterring mice, rats, squirrels, and other common rodents from indoor spaces up to 1291 square feet. The device features four selectable operating modes including TEST, ULTRA, TRANS, and DUO, allowing you to adjust frequency settings based on the specific rodent species in your environment. The automatic frequency conversion design prevents pests from becoming accustomed to a single ultrasonic pattern. Simply plug the chaser into any standard electrical outlet in areas where rodent activity is present, such as kitchens, living rooms, basements, garages, or offices. The compact white ABS housing measures approximately 4.3 by 3.9 by 3 inches and operates on low power consumption of 2.7 watts or less. The ultrasonic frequencies are inaudible to humans and safe around household pets, making this an environmentally friendly pest control solution that does not use chemicals or traps. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. The device includes a power adapter with a 50-inch cable for flexible placement throughout your home or workspace.
