For euthanizing only a few feeders, I prefer to place them into a small tub and use a CO2 cartridge for airguns to dispatch them. To dispense the gas, I used one of the quick inflation devices for inflating road and mountain bike tires, just make certain you get the kind that does not require threaded cartridges, available at online cycling suppliers or local bike shops. The cartridges can be purchased in the sporting goods section of any Wal Mart and are quite cheap. For euthanizing larger quantities, I use a large blanket tub for which I have installed a valve in the bottom that accepts a male/female connector. I then attach a length of hose to a large paint ball gun CO2 cannister, which is then connected to the tub. A regulator allows me to slowly introduce the CO2, which prevents the rodents from panicking, and the rodents are dispatched within a matter of minutes.
While I now acquire all of my rodents pre-euthanized and frozen, the methods I have described worked quite well when I produced and euthanized my own...

Best regards,

Jeff
