Every year I get some stuff from MFA that I can sprinkle in my stock tanks and any other water source that prevents mosquitoe larva from reaching an adult stage. This is a hormone. It will not harm any livestock or wildlife that drink from treated water. I am just wondering if it would have an effect on bees if they drank the treated water. I am waiting for my first package of bees and I don't want to cause any harm to them. Any thoughts?
