FYI

Per an Old Ortho book I have

Ladybugs eat about 50 aphids per hour, If you import 1500 lady bugs
you need over 200,000 aphids to feed them for 1 day. They look around
and say this Joint doesn't have enough food for all of us and they take
off looking in other places.
  If you add 4 parts to 1 part water and spread it on your leaves 
you can keep some for awhile, until the ants find the sugar.

Mantids also have a big appetite, the will eat each other and most
benificials in addition to Aphids, beetles leafhoppers, catapillars,
grasshoppers, wasp and bees. They will chew on a bunch in your garden
and the move on down the road. There is no effective way to keep them
unless you also import a lot of bugs for them to eat.
