Scarecrow-The Best Repellent For Crows

Scarecrow Motion Sprinkler
A scarecrow is made of sticks and straws designed into a human figure wearing pants, shirt and a hat. This figure was attached to a long stick and kept mostly in the gardens or fields to frighten the birds and animals who come to destroy the crops. The scarecrow is moved around with the force of the wind or breeze which scares the crows and other birds away. Among the birds, crows and sparrows are the main culprits who eat the seeds and sprouts from the bedded soils. This type of scarecrow was the only way, before the advent of technology, that the farmers could frighten the birds away at that time.
The recent technical scarecrow which is very popular with the farmers and gardeners is called Contech Scarecrow. This is a motion activated sprinkler system which works by spraying water in the direction of any animal or bird to scare it away. This spray of water is followed by a noise and a shake of the sprinkler head which deters them even more. The area covered by this sprinkler is nearly 1000 square feet and effectively manages to keep most wildlife away.
There are also chemical repellent available which imitate natural substance which repel animals. Most animals are repelled by the urine of their predators. For example a repellent which has the odor of a tiger’s urine will deter most animals. The repellents fall under two types, one is odor and the other taste. Odor repellent work better in warm climates while taste repellent work in cold climates. The deer repellent is the taste one and it works only after it has bitten the plant. So, if one wants to repel a deer, just spray the repellent on to the plant. These repellents are not poisonous so it will not harm the animals only drive them away. It is not harmful for humans and plants too. There are many types of these available and one can even order online.
The other non chemical repellents are barbed wire or electrified fence which has light electricity to frighten them away.  Then there are high frequency whistles which are used on vehicles driving on highways, to scare the deer away. There are a lot of cases where the deer gets in the way of the cars and die.  Each repellent is specific for certain animals, for example a repellent which works on a rabbit will not work on a fox.  There are repellents for domestic animals too, in the form of ultrasonic devices.
