What is Ozone? Ozone is another form of oxygen; it is much less stable than oxygen making it uncomfortable and heavy for pest birds to breathe in. The bird immediately learns that this atmosphere is not substantial for them to nest in, causing them to fly away for good. Our ozone systems are also built to eliminate the harmful pathogens which pesky birds create. The No More Birds Ozone system is custom built for you on demand and installed by one of our professional technical team.
