We are having an attach of aphids in our butterfly and vegetable garden. We wanted to keep the garden free from chemicals so we purchased a bag of 1500 ladybugs and we let them loose this morning.
Bugs, Bugs.... This girl did NOT want to leave the ladybugs.
UPDATE: more than half of our ladybugs were dead and we still have aphids, tons of them. I personally we would not recommend this method.
