How many flies are you putting in there to start a culture?
To answer your question I would say with my cultures once they get going I get probably 2 weeks of booms then production dwindles but they can last a little longer than a month.
I usually put around 50 flies to start my cultures. Sounds like my cultures act the same as yours in terms of production.

The switch to DE was important too. I’ve got about an inch in a plastic shoebox the cups get nestled in.
That's actually why I was asking. I'm trying to figure out optimal time to trash cultures and wanted to see if mine are prematurely dwindling. I wanted to get rid of them 5 weeks after they were first made. So two weeks to get started, than 3 weeks of production/feeding. But so far, they produce very very little after theyve been booming for those first 2 weeks.
