This year I had a number of my Neps hanging in my Sarr house where they grew really well. The downside has been a nasty infestion of tiny destructive caterpillars.

I am still finding evidence of them even although its cold & wintery here now! The first clue is tiny webbing and also what looks like sawdust (droppings!!).
The blithers like to lurk and hide in the new growing point of a plant eating away at it!! And its impossible to get at it without destroying the growing tip!!! Any ideas?

Next year I will add netting to the G/H windows to stop the moths/butterflies getting in
