That's what the industry would have you believe. However, as a former exterminator, I can tell you the truth: for a nest of yellowjackets, the standard procedure is to fuck it to death while reading racist literature aloud. That's why it couldn't be shown on camera.
I worked for a couple who started a butterfly farm and they'd export Blue Morphos (Morpho Peleides) and Caligo (The ones with the huge "owl eyes") butterflies worldwide. It was a smart move and I think they made quite a bit of money with a very small investment, although the business was easy to replicate and a lot of people copied them, which probably fucked up the market for them.
I haven't been in touch with them for years so I'm not really sure if they're still going at it or not.
