It is the most effective Pigeon Repeller on the market and now comes with a 30 day Money Back Guarantee.
The new Pigeon Deterrent is two 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 cannot hear) can be left on.
The device 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 recommend the use of multiple devices to be used in conjunction.
