Ladybug, Ladybug, make this your home

Yesterday I bought a bag of ladybugs. The guys at Home Depot thought that I was crazy when I asked where they were. After all, there was a sign with a price so they should have them, right? Anyway, one guy asked another and the people checking out looked at me like I was released from the hospital when Reagan released them all to live on their own. The checkout guy called the manager to ask about them. His part of the conversation was "Do we have ladybugs?" (pause) "Oh, we do? In the refrigerator?" So, anyway, I bought a bag with 1500 ladybugs and released them in my yard last night. Today I went in the yard and found some on plants and a lot of them on my fence. Soon they'll lay eggs and hatch into more ladybugs. I could buy praying mantis' but I think I'll pass on them.
