Man...that's a f'ing bummer. Sorry bro. I had some massacres like in my first season. Took me 2 or 3 seasons to get dialed in. And even then, nature throws crazy curve balls at you. Some of which you cant avoid or prevent or repair. It can be brutal for sure.
I think, like Matty said, location might be a consideration. It looks like where your plants are now have a lot of other vegetation around them and touching the pot. If I was forced to resurrect my love for growing outdoors (like after last year when I almost lost everything) I'd probably focus on growing photos, and in a more secure location. Maybe a raised bed, or on a sand patch, or a patio or concrete pad.
Either way, sorry for what happened. That sucks. We've all been there, so I feel your pain man. On the bright side, if you ever do decide to brave the outdoors again, you'll be armed with some serious knowledge. Location, preemptive pest precautions, and anything else you learned this time around. And if not, you can kill it indoors!
