3 Pack Bell+Howell Ultrasonic Pest Repeller (3 Pack)

This is a set of three Bell+Howell ultrasonic pest repellers. Key Features & Indicator Lights * Red Indicator Light: The single red LED on the front turns on when the device is properly connected to a standard power source. It typically blinks or cycles intermittently to indicate the device is actively transmitting the variable ultrasonic frequencies. * Built-in Side Outlet: This specific model features a pass-through electrical socket on the right side so you do not lose a wall outlet when it is plugged in.  Optimal Usage Instructions * Clear Path Placement:Ultrasound waves act like light beams; they bounce off hard objects but are heavily muffled by soft materials. Avoid plugging it in behind couches, heavy curtains, or major kitchen appliances. * Effective Timeframe: While minor insect reactions can be instant, allow a full 2 to 3 weeksof continuous runtime to notice a major reduction in overall rodent activity. * Domestic Pet Warning: Do not use this tool inside a room containing pet hamsters, guinea pigs, rabbits, or pet spiders, as the high frequencies are within their hearing range and cause them distress
