Yes ... my tub is even older and it's still working. The key is to keep it in the original tub, somewhere cool and dark I think. I tend to give a the boxes a belt of sulphur burning to start with but then the Dipel keeps them safe later on.Interestingly my Dipel has a use by date of 2021 and I’m still using it,
I had a dead out a month or so ago which was infested with wax moth so I decided to test it’s efficacy. I gave the brood box a good spray from above,closed it up and 4 weeks later there was no sign of any live moth in there.
