Honestly do not remember but I believe it's years.
They have to be protected from drying out. They need to be frozen or close to it for at least 10 days. Longer is better.
But I believe it is a time situation where 1000 viable eggs frozen for a year give you 900 worms. After 2 years it's 500 after 3 years it's 300 etc.
Don't quote me on that. It's been a few years since I researched that.
