There are a large range of Animal Callers on the market. A caller can produce different sorts of calls for the same animal. For example, they can produce a dog calls such as a distress call, bark or howl. Depending on the type you get it may only produce one.
They are for luring in pests that may be timid by nature. Or to attract an animal to a certain area to either be hunted or trapped. Due to our large pest issue the use of callers is practiced more. So management group can be ready for when the pest comes in.
