    Are these safe for bees?


    • Rick says

      Oh, yes. I use these concocctions all the time. The ammonia and vinegar solution cause the bee to stay away until they dicipate and the flowers have been rained on. A bee is a tough, resilent insect. None of these natural, biodegradable solutions harm bees. Commercial pesticides are the problems with bees and butterflies and lady bugs. None of these will harm any beneficial insect in your garden. Just don’t spray any of these directly on a butterfly. Any thing other than water will degrade the silk on there wings.


      • Rick says

        Some of these are mold inhibitors, which decrease white flies as they secrete a honeydew that encourages mold and mildew to propagate. I never like to kill ladybugs either. They are so beneficial to the health of your flora. One ladybug will eat 10 affids per day. Mantis and walking sticks are good to have around too. Any insect with a stiff cuticle are little affected by any of these ingriedients. Bees always shy away from vinegar until it’s odor has evaporated completely.
