Farmers and gardeners often face the problem of animals damaging their yields. Most farmhouses are located near forest areas.  Animals such as deer and rabbit often trespass into the premises and destroy fruits and vegetables. If the farm breeds poultry animals then they can also come under attack from wild predators. In the old days, farmers and poultry owners used guns to keep the animals away. However, law enforcement officers, forest rangers, animal experts strongly recommend that killing the animals is not a very effective solution. Protection of wildlife is also necessary. So alternative methods are being searched, that will not harm the animals physically but at the same time will help to keep them away. One of these methods which is catching up quite well is natural deer deterrent.

Natural, eco friendly sprays and chemicals are being developed. You need to spread them around your plants. These products have been designed to cause unease to a deer or other similar animals. If a deer comes to feed on the products of your garden, then it will encounter the repellent and will be driven away. You can buy these products from the stores as well as make them at home with easily available ingredients. However, the effect of these products on predatory animals is much less. This method is inexpensive, simple although there is a chance that the animals can get used to it after a period of time.
 
Another effective way of stopping uninvited animal guests is putting up barriers. Nets or fences are useful because it can stop both herbivorous and carnivorous animals with equal effect. You need to consider certain points while using barriers- what will be its height, will it be a net like fence or a barrier with metallic bars. Mainly these aspects will be determined by the kind of animals you want to stop. If you are protecting your property against mainly predators, then you should go with strong barriers as they are physically more powerful than other animals. However if you are dealing with something like a deer then you can afford to put up light fences. Compared to repellents, fences are much more expensive and take time and effort to set up. Nonetheless you will get good return.   

In recent years, unique devices have been developed that help to keep away animals by using motion activated animal deterrent. This modern animal deterrent system has many advantages – easy to install, portable, can withstand harsh weather and runs on both batteries and solar power. Once the device is activated its motion sensors get to work. If any animal comes close to the protected area, the device will flash red lights that resemble eyes of a fierce animal. If the animal enters the protected area, the device will flash high power lights that will stop the vision of the animal. If the animal stays in the area much longer a sharp piercing alarm sound will go off that will scare away the animal.  You can use this sonic animal deterrent to protect farm products, farm animals and also other parts of your property.
