Organic slug pellets blue container- re they still available?

Hi

I used to use a certain type of organically approved slug pellets, they came in a blue container... can't remember the brand name. recently I haven't been able to find them anywhere despite having tried different stores at different times. I bought some others, in a red container, but they're not as good- they disappear within 24 hours with no noticeable impact on slug damage on plants.
