Box Tree Caterpillar Spray/Nematodes - Biological Control (Bilton CV22)

Two sachets of Nematodes to spray on box tree/hedge plants.
Biological control for the caterpillars that can eat your hedge to nothing in a couple of days.
They are a week over their use-before date, but have been kept in the fridge, and they are almost certainly still perfectly viable - they’ve certainly got more chance of working if they’re actually sprayed on a plant than if they stay in my fridge until the spring (and then I throw them away!)
I only have one small plant and the first two applications have worked a treat.
I just don’t need to do it again.
These are quite expensive to buy and it seems a shame to waste them.
Collection from Bilton Village, please.
