Has anybody any idea of what to use to kill woodworm - at least I hope it’s woodworm! There is an infestation on one of the beams on our terrace and it’s fresh.
Get some "Tahta Kurusu Ilaç" or try natural methods like injecting liquid ammonia into all the holes with a syringe, then close the holes off with candle wax, or simply put a plate with acorns near the woodworms, hopefully they will leave the beams and get to the yummy acorns...you then can dispose them (back to nature). Good luck, hope you get rid of them!
