I opened a 40 bag of mega bee to use in my candy boards about 2 weeks ago. This bag was purchased last year. Yesterday I noticed small holes in the side of the bag like someone had jabbed it over and over with a ice pick. Powder was leaking out of the holes. I looked in the top of the bag and it was loaded with live small black bugs that disappeared under the powder. I poured the remainder of the bag in a 5 gallon bucket, sealed it and popped it in the freezer.
sounds like weevils to me

Glad I put mine in a plastic garbage with lid can in the basement. I've had that happen to a smaller bag in the garage. Small moths came out when it was reopened. :shock:
I would not worry about it. Freezing will kill any bugs and bees won't mind.
