Ideal for certain sites, but the stroboscopic and sonic elements may result Ultrasonic pigeon & bird scarers that combine ultrasound with distressĬalls are undoubtedly an ‘all-singing-all-dancing’ product that may be Due to the nature of ultra high frequency sound-waves that spread out in circular waves from the source, a multi-speaker unit with 4-speakers ensures that the sound waves overlap, providing total coverage. Some units also offer the option of installing extension speakers for use in areas that are architecturally complex. Two manufacturers also offer an environmentally friendly solar panel option allowing the battery to be ‘topped up’ when exposed to daylight or direct sunlight.ĭue to the fact that ultrasound travels in straight lines and will not pass through solid objects, a system providing multiple speaker options will provide the most comprehensive coverage. Some manufacturers offer their range with a mains adaptor giving 12 volts DC as standard but will provide a unit with connections to a wholly DC power source (normally car/leisure battery) on request. Most ultrasonic pigeon & bird scarers are powered by mains electricity in an effort to provide the user with a maintenance-free option. Many systems also offer the potential to ‘daisy-chain’ or ‘slave’ additional speakers. If using a multi-speaker unit to provide 360° coverage the speakers can be sequenced in rotating order at speeds between 10 rpm and 110 rpm.

Most units are extremely simple to install and require little or no maintenance. Ultrasonic units are available for internal use (including external areas that are protected from the elements) and also for non-protected external use in open-air environments. The principle of an ultrasonic scaring device is to saturate an area in which birds are roosting or perching with high frequency waves that are unpleasant and irritating to the birds but which are harmless. Whichever unit is chosen there must be an understanding that sonic sound, strobe lights, distressĬalls all create noise that is audible to the human ear and may cause considerable nuisance to those within hearing range.
