Bird repellents sweep birds away with rotating arms. These accessories are usually solar powered with rechargeable batteries so that they can keep running even during dark times. They keep pest pigeons and larger birds off of patio furniture, patio covers, even boats and docks.
As the word suggests, sound deterrents are used to scare birds away through making loud sounds. They are predator calls and distress calls played in short intervals. The sounds being made trigger the birds instincts to danger and they will go away. Remember, you should go with a sonic sound unit that is water proof and easy to program.
As far as visual repellants are concerned, they create a visual distraction that causes birds to fly away. And flash tape is one of them to be used in garden areas. It can be mounted on the poles in your garden to keep birds away from plants and seeds.
As far as bird flight diverters are concerned, reflective ones looks like predator eyes when hung in trees. These diverters have a reflective eye on one side and when the birds see it moving in the breeze, they will leave the area for a safer neighborhood. They are ideal to use in fruit trees so that pest birds don’t eat the fruit. You will find them usually in the pack of five which will give you a bird free atmosphere in the garden area. Before going with any of them, you must consider which pest bird you want to keep your yard safe from. So, go for it now!
