Reader Questions – How Long Do I Freeze Eggs For?
You are right, freezing eggs is the best way to make sure they don’t hatch and it’s not cruel at all.
Leaving the eggs in the freezer overnight is usually long enough and once eggs are frozen the embryo will die, so no, they don’t become viable after you take them out of the freezer.
Putting them in the bin should be fine, or you could bury them if you want to.
Good luck with your new snails!
