Ladybugs (Coccinellidae) can do the work that nasty chemicals used to. Researchers in Japan have discovered a way to selectively breed flightless ladybugs to be used as a "biopesticide" - a natural alternative to chemical pesticides.
Ladybugs have long been considered natural pest-control for gardens and crops, but their ability to fly away encouraged many agriculturalists to instead rely on chemical pesticides that are harmful to the environment. After several generations of being exposed to chemicals, many pests have also been known to develop pesticide resistance.

The problem is that they are too efficient, eat all the bugs, and then fly away to find more food elsewhere.
The advantage of the new flightless ones is that they will either starve to death (keeps the nice color touches in the garden, an attracts new bugs), or get eaten by some very very happy birds.

it does seem a bit cruel

Why is it a problem? 3 weeks ago I started to get Aphids on my balcony, ladybugs came, now I have ladybug larvae having an all-you-can-eat buffet with the Aphids. They will turn into Ladybugs and go eat somewhere else.
I really don't see the problem, only nature acting like it was designed to.

From TFS "but their ability to fly away encouraged many agriculturalists to instead rely on chemical pesticides".
Killing all the bugs on my plants once every now and then is fine for me, because I don't make a living out of the crop yields.

So repeated buying of chemicals is OK, but repeated buying of ladybugs is not? Why?
The Tao of math: The numbers you can count are not the real numbers.

They clog the spreaders' pipes?
I'd venture a guess that farmers prefer to go Saddam on anything that moves, rather than trust the little buggers to spread correctly, stay in place more than five minutes, not attract bugs, and actually have a taste for every threat.
If you have to spread again for something else (fungus? caterpillar?), it doesn't stack very well with the ladybug protection.

Easy! No intellectual property in ladybugs! (Unless. . . hmmm, ladybugs with lasers on their heads? Very small lasers? But then we would want them to fly.)

Apologies, I didn't mean that you shouldn't buy Ladybugs, I meant more the article ones that can't fly and are condemned to either starving or being eaten (which I'm sure is unpleasant). I don't consider it a major problem but nor do I consider it best practice.
