dry ice

does anyone know where to purchase dry ice from for mouse euthanization purposes.

Many grocery stores carry it.

Make sure to do it right, or not at all.

Moved to General Feeders section.

Yes, i see it at grocery stores and unfortunately they come in about 10lb blocks...expensive, and you don't use it all when you have to put down 5 or so mice....so uhhh normally you get about 9.5 pounds of dry ice that you're soaking in water because it's cool to see the foggyness it makes or you throw it in a hot tub or something :P

I would go pick up a CO2 canister and fill it with CO2 - and create a CO2 chamber. Cheaper, not wasted dry ice (dry ice will not last in your freezer)

Yup, by and large CO2 canister is cheaper, in short term and long term!

You can also use baking soda and vinegar to make CO2.

I have a spare 20 gal tank that I use. I put a small rubbermaid tub (12qt?) on one end with a gallon of vinegar in it. Place your rats, mice, ASF, etc.. in the tank. Then over the course of a few minutes slowly pour 10oz (volume) of baking soda in. If you do it to quickly it fizzes over and the rats freak out. Once you've poured all the baking soda in just let it sit for 10 or 15 minutes and when your all done you have nice humanely euthanized rats.

Also, CO2 is heavier than air so the container you use doesn't have to be air tight. I leave the 20gal open until all the baking soda is in then I put the mesh lid back on.

Last time I did it I only did 8 small rats but I could easily do 20, if not more in the tank.

The total cost for ingredients was $2.75

1 gallon of vinegar and 10oz of baking soda makes 20 gallons of CO2, so if your going to use a smaller or larger tank just do the conversion.
