Why can you buy ladybirds in some garden centres?

2
We take for granted the fact that we sometimes
see ladybirds in the garden, but some garden
centres are now starting to sell them. As more
people start to believe that we shouldnt use
pesticides and chemicals to protect plants, they
are looking for alternatives. Ladybirds are a
natural predator on insects like greenfly.
Greenfly can damage plants such as roses, so if
you have an infestation, releasing ladybirds is
like letting lions loose on a herd of cows. The
ladybirds clean up the greenfly and do not damage
the plant in any way.
