Does mouse poison lose its effectiveness?

Question

I have two buckets of Lipatech Generation and Contrac Blox professional mouse bait. When I first moved into this house 10 years ago the mice would go through these things like crazy in my basement. Since the basement was sealed up I have not had any problems but now I have at least one mouse in the unfinished attic. I put these cubes in the mouse stations and also placed some out in the open.

I'm not getting any takers or bites on these. Both buckets are about five years old now. Do they loose they attracting appeal this quickly? It's almost as if they "know" what the deal is.

It's a hard dry cube kept in a "cool dry place."  Yes I would say fiveyears is quick.

What's the attractant? One would presume it's fairly aromatic so that either simply evaporation of the more volatile components or a slow oxidation would be highly likely.

What's manufacturer's published expected shelf life? I'd be surprised if it were over a year at most...

I have had customers over the years with contract baits placed in areas for years...whether it was they were 3-5 years or 5-10 years I don't recall but there have been numerous times that all of the sudden I would get hits on the baits. If you notice, the contrac blox have a hole on the center of the block...pack it with peanut butter.
