Ultrasonic pigeon & bird scaring systems have been introduced into the pest control marketplace due to the fact that ultrasound is too high-pitched for human hearing but falls within the hearing range of most species of birds. Most sonic bird scaring devices produce a sound that is audible to the human ear and therefore may cause human disturbance if used in an area of human habitation.

Ultrasonic systems can be used in a wide variety of locations without causing human interference making them an ideal choice for areas where noise-related scaring is not an option. The exception to this rule may be where women and young children are concerned. With age, the human ear looses the ability to hear ultrasound but in some women and particularly in the young, ultrasound falls within hearing ranges and can cause considerable discomfort and headaches. This may have the effect of restricting the use of ultrasonic pigeon & bird scarers when used for pigeon control and gull control in urban areas and on industrial sites.

A constant 15-25 KHz setting (15 KHz for external model)

  • A variable setting allowing the user to modulate the frequency between 15 and 30 KHz with different speeds or ‘warbles’ (15-25 KHz for external model)
  • A high/medium/low frequency setting
  • A combination mode which alternates the ‘constant’ frequency and the ‘warble’ output in timed bursts
  • Up to 6500 sq feet coverage (3600 sq feet for external model)
  • Power consumption: approx 10 watts (depending on brand)


Most ultrasonic pigeon & bird scarers are powered by mains electricity in an effort to provide the user with a maintenance-free option. 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. Two manufacturers also offer an environmentally friendly solar panel option allowing the battery to be ‘topped up’ when exposed to daylight or direct sunlight.

Due 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 units also offer the option of installing extension speakers for use in areas that are architecturally complex. 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.

The ultrasonic pigeon & bird scarers that combine ultrasound with distress calls,strobe lights and predator calls are undoubtedly an ‘all-singing-all-dancing’ product that may be ideal for certain sites, but the stroboscopic and sonic elements may result in the unit being considerably less versatile in an urban application. As a roost inhibitor, for areas rarely frequented by humans (for example the underside of a railway or river bridge), the multi-faceted device would be entirely appropriate and may offer high levels of protection. However, the lack of an AC power supply in this type of environment will inevitably make the product more labour intensive. It is clear that the combo units are species-specific and based on their potential to create human disturbance, these products must also be considered to be highly context-specific.
