I always felt bad for em, we either drowned them in alcohol or froze them. I also felt guilt boiling the ecoli I spent time genetically engineering (in a genetics uni lab)
I have rescued so many fruit flies from my beer. You hardly need to drown them, just present them with a 5% ethanol by volume solution and let them drown themselves
(My beer system is outside in my courtyard, fruit flies love the drip tray)
