The new Pigeon Deterrent is the most effective Pigeon repeller on the market and now comes with a 30 day money back guarantee.
The Pigeon Deterrent is actually 2 machines in one. It has ultrasonic frequencies plus a sonic (audible) sound generator which produce non-natural harassment sounds plus some bio-acoustic predator and distress calls of actual birds.
If necessary all audible sounds can be turned off and just the ultrasonics (which humans cant hear) can be left on.
The Pigeon Deterrent comes with four speakers - the ultrasonic and sonic frequencies cycle through all four speakers. Ultrasonic frequencies play 24/7 whereas the sonic sounds can be programmed to suit your individual circumstances. Each speaker is independent, and comes with 30 metres of cable.
For larger areas we strongly recommended that the Bird Gard Laser (a hand-held laser) be used in conjunction with the Pigeon Deterrent. The Laser will remove pigeons and swallows instantly - while the Pigeon Deterrent will continue to operate 24 hours a day.
