I think it was Nemasys I used. It worked well, but they are probably all pretty much the same. It will be one nematode I guess. Wait till it’s warmer though. Evil weevils…hate them!

ok thanks for that I bear it in mind

Also the adults only lay the eggs when they can smell the compost/soil in the pots. So, put a good 2 inch deep layer of fine gravel over the top of the soil. That usually stops them
A Neem Oil drench does work and is less harmful to other things than the usual insecticide stuff.
