The nematodes were watered in 2 days ago and here's hoping they work. The caster oil granules went in the week before that.
Yesterday was the first time we didn't see a molehill in the morning, but the runs are all over the grass, as we felt them while walking over it with the watering can.
The mole repellant is still buzzing away, and one of them is now stuck down a hole in the middle of the grass.
It's too early to say whether the caster oil granules have worked, or that it's eaten all the leatherjackets, or maybe moved off somewhere else, but I'll be back on here to let you know if it returns in the future.
Thanks again to everyone for your helpful suggestions.
