The first is the Conference on Disarmament.
Experts' research shows that birds' eyes are afraid of colored light, especially the flashing colored light will make birds afraid. Colored lanterns are not effective in strong light, and their deterrence is not strong. CD is a good choice.
Methods: Connect the discs in series with a rope. The two ends are tied to the balcony, facing the wind, the CD in the sun will start to shake, and the colored light will keep flashing, which is very dazzling. Birds will run away as soon as they see colored light. However, this method is not suitable for houses with close building spacing, and the neighbors opposite will have opinions.
Second, it is ribbons.
If you are worried that the CD is too dazzling, you may wish to tie a few ribbons on the balcony to drive away the birds, because the ribbons can reflect light and stimulate the birds; And when the wind blows, the ribbon makes a sound, which makes the birds afraid! It is suggested that the ribbon be hung about 20cm higher than the potted plant. If it is hung directly on the flowerpot, the effect will be very poor.
Third, natural enemy intimidation.
Look for some pictures of natural enemies of birds, such as cats, eagles, snakes, dogs and so on. Print it out and stick it on the balcony, and the birds will be scared away.
Fourth, use water to drive away birds.
This method is more suitable for driving birds on the terrace or by the pool. It is suggested to buy an induction nozzle and put it in the place where birds haunt. If birds want to get close to this place, the sprinkler will automatically spray water to scare them away. Don't worry about water impact, this method won't hurt birds.
5. Play the noise of the bird repeller.
If the bird is sick, you can find a small stereo to play the noise of the bird repellent. Play the noise for many nights in a row, the effect will be obvious, and the birds will leave on their own after hearing the noise.
Conclusion: The above five methods of repelling birds from the balcony are mild and won't harm birds, so you can use them with confidence.
