Anyway, despite the cupboard disinfecting efforts, I put a new sealed tupperware container of new flour in the cupboard, and a new batch of little crawly things promptly appeared around the container within 24 hours (so I guess they came from somewhere in the cupboard rather than from inside the flour).
Anyone else dealt with these before? I'm wondering if I should start putting flour in the fridge or freezer instead? Or perhaps I need to disinfect the cupboard again?
Thanks in advance
