Do you have a problem with pigeons?
Some people call pigeons "rodents with wings" and the reason for this is that they can not only make a big mess of your property, they can also spread germs and diseases.
Pigeons can carry many diseases, such as Cryptococcal Meningitis, Salmonella, Listeria, Viral Encephalitis and E. Coli. When pigeon droppings dry up, they become like a dust substance that can easily be inhaled in the air, creating a high chance of spreading diseases.
This Pigeon Repeller app plays the sounds of various birds of prey that pigeons are extremely scared of. Just play it nearby any pigeons and watch as they scatter and not return for quite some time!
This app works offline and a blast of around 2 minutes should scare the pigeons away for at least an hour, however, if they come back, play the app for a while longer, until they scatter and for a couple of minutes afterwards.
This app will not cure your pigeon problems in the long term. You should make sure your property is clean and no left over food, bins or animal food is left outside to reduce the problem. Cover any possible holes that pigeons could use for nesting and place herbs and strong spices in places where they are known to sit.
