What’s Killing my Hedge!

Pity, because I like the smell.

Those box caterpillars are a menace.
I fought them for 5 years and managed to keep the plants alive.
Then this year I gave up.
The caterpillars became immune to all insecticides, I tried specific ones and home made, spending a small fortune.
The plants died and I pulled them out.
Unfortunate but that's what happens sometimes.

Did you try the nematodes?

Probably, I don't remember all of the products I bought.
The most effective was called xen-tai or something similar but the little buggers became immune to it.
