If you have a problem with Indian Myna Birds you will probably have found the advice to get a trap and catch them. This is a good solution as it will reduce the population, but it takes some effort. If you want to simply move the birds on, so that they stop pooping all over you house and belongings, I have a very easy way to do that.
Get a water pistol!
I dont mean a little one, but a Super Soaker type arrangement. These birds are increadbly aware of being hunted. It only takes a couple of days of targeting these birds with water, and they will packup and leave. Abiet propably only to your neighbours house – but thats their problem!
