Where can a guy buy ladybugs from that is not a scam?
Heck, I'd like to invest in a bunch of Mediterranean Geckos and Green Anoles, too.
I would think of the 'zards as my Hessian Mercenaries hired/bought to kill the roaches/water bugs here'bouts.
Not always a good idea to introduce non-native species
en masse to an area; consider that if there was an ecological niche appropriate for such critters in your area, probably there would already be critters like that in your area, filling that niche.
I seem to recall hearing that many "pest" species were brought into an area by people in order to stop another (generally indigenous) unwanted critter, and got out of control.
For instance, Kudzu was brought in, IIRC, to act as erosion-preventing ground cover, and it's gone and eaten rather a lot of the South.
