We had a customer come in today and was after some powder Alum (floc) to stop most parrots eating and destroying the grass they have in there garden. After many attempts to stop the parrots from eating the lawn and seed. They came across some information from the Burkes Backyard website.
Simply add 1 teaspoon to a litre of water and spread it over the lawn. Apparently this produces a taste which the parrots dont like and with nothing to eat there will move on without harming them.
We readily have it on our online store: http://www.epools.com.au/swimming-pool-chemicals-swimming-pool-maintenance-chemicals-c-536_1142_1147/alum-pool-floc-2-kg-p-7969.html
