Buying Pollinators (Bumble Bee Box)
I have seen a few places selling boxes of bumble bees that you place in your garden.
Is this one of those things that sounds good but is actually a horrible idea? E.g. introduces diseases to local populations, etc... OR is it a good way to boost local numbers of insects.
If it is beneficial, does anyone know of good sources for invertibrates? What are the best to get?
