Hi, Have 8-10 kgs of various forms of Pu'er (cake, brick, tuo) stored in a reasonably tight hardwood cabinet (it's not air-tight). No holes or gaps in the cabinetry. The tea is wrapped in it's original paper wrapping and cartons.
Conditions inside are reasonably stable - but we do get the odd hot day here in summer.
Anyway, I opened a 1990's cooked cake last night, one that had been opened before, and I saw a minute bug, or mite. Very small - I'd say as an estimate in size, say 0.1mm - really tiny. I checked the rest of the cake as best I could and could not see any others.
Is this normal ? If not, is there anything I can do about it?. Our house is kept reasonably clean and we have hardwood floors - so no carpet for things to breed in.
Would appreciate any insight.
