In this post, I want to explain the various types or categories of frightening devices. In a previous blog article https://wildlifecontrolconsultant.com/frightening-devices/, I explained that frightening devices are pieces of equipment that attempt to get unwanted wildlife to leave an area through the use of fear. Fear invoking products can only be categorized as a frightening device if it causes fear by non-chemical means. For if chemical means are used, then the product would be a repellent and likely governed by the Environmental Protection Agency (EPA).
Categories of Frightening Devices
We need categories to organize the frightening devices because there are a lot of frightening devices. Frightening devices are categorized by mode of action, namely how the animal experiences the device. The modes of action are visual, audible, audible-visual, and biological.
Visual Frightening Devices
Visual frightening devices as the name suggests use light to frighten the animals. Visual frightening devices include active lighting products like lasers and strobes as well as passive devices that use sunlight like Mylar tape and mirrors.
Audible Frightening Devices
Audible frightening devices use sound to frighten animals. These devices use irritating noises like gun shots, distress calls, or predator noises to frighten animals from an area. One challenge with audible frightening devices is that they can irritate neighbors who happen to be in listening range. Ultrasonic devices are included in this section, but be warned most animals cannot hear in the ultrasonic range.
Audible-Visual Frightening Devices
Audible-visual frightening devices combine sound and light to frighten animals. Pyrotechnics such as bird bangers are a classic example of this type of device.
Biological Frightening Devices
Biological frightening devices try to exploit the innate fear animals have of predators. Dogs, hawks, snakes, etc. are examples of biological frightening devices. Since prey species have innate fears of these animals the idea is that the prey species cannot habituate to them.
Bottom line, by being aware of the categories of frightening devices, you can mix and match them. If audible didn’t work, perhaps you should try a visual or a device from another category.Stephen M.
