Hi Natali - welcome to permies!
I agree with Chris although I'll tell a related story: The first spring after I arrived in BC corresponded to the 7 year high in tent caterpillar cycle and the
apple trees near the house were being consumed. My husband insisted on trying the "burn them approach" but I was afraid there wouldn't be much of a tree left. Instead, every morning I went out wearing rubber gloves, pulled the tents off and stomped on them on the driveway. I also learned that if I saw a tent caterpillar with a white dot on it, it had been infected by a parasitic wasp that would get the whole problem under control if the "white dotted tent caterpillar" was allowed to live. That
experience got me moving towards
permaculture - working with nature, so she'll help us out.
So Chris's approach will save this year's crop, but reading lots of the forums here at Permies will help you follow that up with Nick's approach and the many other things we do here to promote a healthy, inclusive, diversified garden/polyculture/food forest that will help prevent a single troublemaker from invading in the future. I leave any wasp nests that aren't in a problem location and that aren't being aggressive towards me, but I also leave plants to go to
seed so the birds will hang out and eat bugs, and the ornamental
pond installed by the last owner is largely left alone during tadpole season. I've been here 20 years now and I see birds, snakes, frogs and friendly wasps all the time. Last year I had to apologize to a tree frog who was hiding in the lettuce plant I was picking leaves from. I thought the squishy feeling was a banana slug I was going to have to re-locate, only to discover a ticked-off frog! I carefully replaced it among some leaves I wasn't planning to pick.
If you want to do double duty, find someone with chickens and see if they like them. (Chickens *don't* like the taste of tent caterpillars.) I had a friend who was having a bad slug problem and she used to save her slugs in a
bucket for my ducks. Once she got her garden diversity up, the slugs no longer took over.
