shelf life of Fumagilin

[Eric Walls]

I have some Fumagilin I was keeping in my fridge and while cleaning out I noticed that it expired last year. Use it, or toss it? I used it last year in the spring for one feeding, but haven't in other years. Don't know if it really makes a difference or not.
Thoughts?

It should be fine

I have used it a year past expiration with success.
BUT you DO need to feed more then one time. At least 3 treated feedings.
Otherwise a person is raising "super bugs". Then it will not work any longer.
