>>992702Paper wasps are your friend. Make some insect hotels for them to live in and build nests.
https://www.google.com/search?q=Paper+wasp+eating+caterpillar&tbm=ischThey are like little Russian-built attack helicopters against caterpillars in your garden. I've not seen them on big tomato hornworms, but they go nuts on cabbage moth caterpillars. Mason wasps will do it too, but not to the extent that paper wasps do.
They can be one helpful ally at least. Whenever I find a nest in the blocks of my raised beds I make sure to leave it alone so it can get bigger and I don't disturb it and get stung.
