The old straw occurs to me, if it ain't broke don't fix it. My wife ordered five bucks plus shipping worth of ladybugs, to fight garden pests in an environmentally friendly way. It fell to me to distribute the "girls" when they arrived, cutting the corner off a little net bag where they were dancing around, and gently scrapping them off the outside of the bag where they soon relocated, onto the leaves and stems of our garden. I'd already powdered the vicinity with their starter food, to get them going on our local aphids and other edible ladybug food. I think there were supposed to be 1,500, distributed over various small gardens and planter stands. The next day, I spotted two, and since I have not seen a single one, ever. So they have retreated into various secret hiding places, or more likely they have de-camped to what they sensed were juicier plants off the property, or some kind of predators arrived and ate them up with relish, or without relish. Yum-yum. Good business plan, to send bug across the continent to promptly disappear.
