Should Repashy Superfly be replaced every 6 months?

Not sure if it is just for the supplements, but would like to get the big jar of superfly as it provides lots of savings in the long run. Currently I've been doing the middle size jar and takes maybe just under 3 months to go through. It would probably take me around a year to get through the big one, would keep it refrigerated.

You should be fine provided you close the top tightly and keep away from heat. Fridge while beneficial is likely not necessary unless your ambient indoor temps are constantly in the 80's.

I buy superfly in bulk and have had some go for longer than a year with no noticeable issues in fly production or molding. Actually I have had NE Herp and Josh's media last for years after being opened with no noticeable diference in fly production. Keep in mind I live in Los Angeles so I don't have much in the way of humidity to deal with so your mileage may vary.

Thanks for the input, if I buy the big one it is about 40% cheaper so that is good to hear.
Vitamins in the SF will degrade in the same way as they do in supplements. But since the FFs aren't carrying any real amount of vitamins in their tissues that pass on to the frogs, they only need enough to reproduce well, which apparently is found in simple potato flakes (of any level of freshness). The carotenoids in SF might be a different matter, though that can be offset through supplementation if it is an issue at all.

If a person keeps any other herps, FF media can be used up quickly as food for other feeder insect species (roaches, crickets).

No other herps for me, so I doubt I'll go through it that fast, although hopefully I'll have some terribilis froglets so that might use a bit more.
Although it was really interesting reading the study in this post: Super pig showing that adding carotenoids to the fly media for the parents may result in healthier froglets in addition to rep cal+ dusting, which if correct could lead to the fresher media being better (if the effectiveness of the carotenoids is reduced in old media). Lots of 'if's' in that statement though.
Perhaps with some more experience I would be better able to understand if there is a big difference at all, was just hoping someone else had already gone through it!

A quick web search for 'carotenoid degradation storage' shows that this degradation is well studied, and is a function of oxygen, time, temperature and illumination levels. Whether avoiding it is worth the extra trouble for one's own purposes is another question.
