Lightweight and comfortable to wear, the tick and flea protector has a coverage radius of approximately 1.5 metres and is suitable for dogs and cats of all sizes, short or long haired. Resistant to splashes and moisture (IP41 protection), ZeroBugs™ PET emits a random frequency of ultrasonic waves - completely harmless to humans and pets - which act on the nervous system of ticks and fleas, preventing them from detecting the potential host and feeding. Once activated, the internal, non-replaceable lithium battery lasts for approximately 310 days, sufficient to cover the critical period for pest proliferation. The product is equipped with a push button and LED to check it is operating. The continuous action of ZeroBugs™ PET reduces the risk of colonisation by ticks and fleas, vectors of serious medical conditions that affect dogs, cats and humans. The ultrasonic repellent can be safely used on puppies, the elderly and any animals that come into contact with children. The efficacy and compatibility of ZeroBugs™ PET with animals and people of all ages have been tested at the Department of Biomedical, Surgical and Dental Sciences of the University of Milan.
