well it seems these teavana containers are not so air tight...
probably that allowed any larva to grow and multiply (5months) into a
whole colony occupying the container, reducing the plant and flowers
to a mulch...
this is a little 2mm long brown little flying bug, obviously not small
enough to escape the container and eat all my tea
yup, organic... great...
Those little critters sound a lot like "grain moths" which are common
this time of year. They are also common in stores that sell "bulk".
From the research I've done on our own invasion (courtesy of Whole
Foods) they are apparently harmless , although creepy. In ridding
ourselves of them we dumped most everything and taped bay laurel
leaves to the top of each container (outside) which has inhibited any
re-infestation.
Also, organic gardening stores online sell sticky traps which can go
into your cabinets and they work very, very well.
Hope this helps.
