Protecting Orchids Against Aunts with Borax

We find a good way to control ants in the greenhouse, rock garden, around the house generally is to add borax ,available in large supermarkets--at least here in Canada-- to Carnation millk until a stiff paste is produced. We add a little red coloring.Mix thoroughly and drop little 'cookies" onto wax paper. In a few days the cookies will become solid and they can be placed along the ant paths or in pots, etc. Be sure to keep them away from kids and pets. Borax carried to the queen usually cleans up the sand piles. Good luck... OGD
