Try Jon at Thegreengardener.com He supplies nematodes particularly to fight this issue. It might take several applications over a few months, but it really worked for me when I moved to a new house. Nematodes mixed with water and applies via a watering can. Treat autumn and spring
Yeah thanks that's the guys I've used the last couple of years. Cheap and simple at 100sqm pot. Hopefully that they are on the surface means they are dead but for the sake of £15, I might get another box in a couple of weeks.
Certainly is horrible to think about it and I saw a story the other day where nematodes were found in drinking water lol
