Sometimes, it can just take a little audio discomfort for birds to decide to evacuate your property. A well-known and effective method is simply to play loud music, but naturally, this is quite disturbing, both to yourself and to any neighbors. Thankfully, there is a way to cause just as much audio discomfort to birds but not disturb humans. Birds have more enhanced hearing than us and therefore can hear much higher frequencies. There are many audio kits in production that are specifically designed to play at a high enough frequency to cause audio discomfort to birds but leave humans unscathed. These range from small home kits to enormous, multi-speaker kits designed for warehouses and farms. There are even apps that can be bought that do the same sort of thing. Birds do not like bright lights as they cause discomfort and affect their night vision. Therefore, by having movement sensitive white lights, it will make life a lot more difficult for birds on your property. However, this may cause a nuisance to yourself too. Finally, a more practical approach is to invest or build your own, bird spikes. These make it simply impossible for birds to settle on walls as there is not a flat surface. These are not popular with everyone, as they look imposing and can be expensive. Nevertheless, they are perhaps the most effective way to prevent a bird infestation on your property.
