I forgot to tell you how we’ve been trying to destroy them–the Butcher has been shooting their tents.
I don’t know why this is working, but it is. I hypothesize it’s because it makes it harder for them to regulate the temperature in the tent and it gives the birds access to the innards, but so far, we’ve not seen the massive, teaming infestation that ate our roses last year.
Knock on wood.
Edited to add: With a bb gun.
what kind of caterpillars do you have? Are they green? For some reason I am picturing catalpa worms when I read the word “tent”

No, nothing that exciting This is them.

Whoa. Those are gnarly. And gross.
Oh, they get grosser! Look at what they looked like last year and see why I have no compunction about trying to kill them this year.
