What Is an Ultrasonic Animal Repeller?
An ultrasonic animal repeller is a device that emits ultrasonic sounds at regular intervals. It typically uses carbide or propane gas as fuel. These devices are used to deter wild birds, wild boars, deer, and other pests from entering farmlands and damaging crops. When deploying ultrasonic animal repellers, it’s important to consider and inform the surrounding environment.
Uses of Ultrasonic Animal Repellers
Ultrasonic animal repellers are primarily used in agriculture, such as in orchards and fields, to prevent damage from birds like sparrows, pigeons, starlings, chickadees, and crows, as well as from animals like deer and wild boars. They are also employed in cattle sheds, livestock barns, ranches, aquaculture farms, and even at airports to prevent bird strikes.
Features of Ultrasonic Animal Repellers
Advantages
These devices effectively deter pests from invading and damaging crops. They are often used alongside other protective measures like bird nets and electric fences, enhancing their overall efficacy.
Disadvantages
However, their effectiveness can be temporary or continuous depending on the installation timing. Continuous use or combination with other methods may be necessary for long-term effectiveness. Additionally, consideration of the surrounding environment is crucial, as the noise can disturb nearby residents. Some localities may recommend alternatives to ultrasonic repellers.
Types of Ultrasonic Animal Repellers
1. Classification by Installation Method
These repellers can be installed directly in fields or hung from trees or poles. The hanging type is more convenient for mobility.
2. Classification by Explosion Interval
Varying intervals between sound blasts are designed to prevent pests from becoming accustomed to the noise. Some have irregular intervals, while others have longer gaps.
3. Classification by Type of Detonation
Different detonation sounds like sirens, barking hounds, or firecrackers are available. Selection should be based on the sensitivity of the targeted pests.
4. Classification by Function
Some models include additional features like visual deterrents, solar-powered operation, sensors for vermin detection, or night-time light emission for enhanced effectiveness.
How to Choose an Ultrasonic Animal Repeller
Selection should be based on the specific pests to be deterred, the surrounding environment, and local regulations. Performance features like explosive sound or light emission should be considered based on the time of use.
How to Use Ultrasonic Animal Repellers
Typically used in fields and orchards, the blast interval of these repellers can be adjusted. It’s essential to be mindful of the impact on residents, especially when used near residences or during early morning and night hours.
