Bird do-do on plants!
Got a problem. There are MANY birds roosting in a tree. The droppings are all over the plants below to the point it stinks. To the point it may be a health hazard. Bird crap covers a retaining wall 2 weeks after pressure washing it. Enough is enough!
Soon will try using a "squack" box to keep them from roosting there. Gives off loud birds of prey noises to scare them off. Anybody know about these? Do they work?
Also, is there any way to clean all this bird crap off hostas etc.? Tried spraying it off with a hose with no success. Have no idea where to pose such a question, wildlife seemed logical.
