Predator birds always attack from above - This is why all birds are alarmed when they detect a moving object above them.

Helium filled balloons, which are flying at 10 - 30m high makes use of this instinctive behaviour - birds avoid roosting under our birdkites, which makes them an effective and inexpensive bird control method.

• Birdcontrol balloons are helium filled kites and fly permanently at a certain height, which is fixed with a long rope.
• Birds see the balloons instinctively as a threat and avoid them. Birdkites may be used to deter all kinds of birds (besides predator birds).
• Because of the height, at which birdkites can fly, also large areas up to 10 hectars can be kept almost bird-free. This makes birdkites a very suitable tool for agriculture. The higher the balloons fly, the more effective they are.
• The birdkite principle has been researched and approved by well-known universities.

• Habituation is very seldom, but can be seen during breeding season.
• Birdkites are available in two different versions. Another version is the Hawkkite. Alternatively we offer birdkite decoys, which are fixed to kite poles and can move freely with the wind.
  
• The external skin of the Birdkites must be exchanged once per month.
