Hello,

More than a year I got this bugs in one room in our house.
I kill them, but they coming back, and multiply in insane rate.

There is the larva [img] (Hard to see: yellow body, black head)

He grow into little butterfly [img] (Black/grey-dirty color, they don't dragged to light - tried light electric fly killer)


Anyone can indentify what is this, and how can I get rid of them for ever?

Thank you!
