Wireless Ultrasonic Pest Repeller Viano King Rodents Martens Mice 250m Range (ODA2)
Description
VIANO KING – Wireless Ultrasonic Marten and Rodent Repeller
VIANO KING is a professional wireless ultrasonic repeller designed to protect photovoltaic installations, lofts, garages and other structures from martens, weasels, mice and rats. The device features 4 piezoelectric emitters and a built-in 4000 mAh battery, providing up to 200 days of operation without recharging.

Why VIANO KING? Martens and rodents pose a serious threat to electrical and photovoltaic installations. Cable damage can lead to costly repairs and even fires. The VIANO KING repeller generates ultrasonic waves at varying frequencies that are unpleasant for pests whilst remaining inaudible to humans, dogs and cats.
