Squishing stink bugs, wasps to the rescue?

A fellow gardener, was saying how terrible the squash bugs were this year. She wanted to know what I do to protect  my squash?  Like an idiot I said I don't do anything, with the exception of a little aphids on my beans in August I don't really have bug problems. I know better than to challenge mother nature like that. ( Advice was to keep picking them off, and if that isn't enough to check the Internet for organic solutions. Next year don't plant all her squash together) I don't have squash bugs, but I do have stink bugs, and maybe cucumber beetle, I'm not sure, I don't really know bugs.  I was watering late the other night and it was dark so I had a flashlight. I start to see stink bugs. I had flower scissors so I cut them, and squished them.
I have been on the lookout ever since. I have only seen a few. Tonight I removed all the leaves below the zucchini, and removed the borage I had down as mulch (put it in a bag and put it in the garage.) In my main garden I found a couple bugs and no eggs. By the time I made it to my outer garden I was totally dark. I was finding eggs, I was removing them. I started to get bombarded by what I thought were wasps. I didn't think wasps flew at night, plus I was in this part of the garden earlier and didn't see one wasp. What ever they were there was a lot, and they were coming at me and my light. Several  landed on me, but I didn't get stung. When I was young I got stung by a bee. I had a nasty reaction, not life threatening, but a lot worse than a normal reaction. The doctor said I should be very careful because the reaction can get a lot worse, or I could grow out of it. I have never been stung since, so I'm careful. I called it a night.
My husband said wasps don't fly at night, so I wonder what they were? They were coming from the squash that has the most damage, and the only one (so far) that I have found eggs on.  What ever they are I hope they are some kind of predator bug, and help keep the stink bugs in check.
Everyone thinks I'm a nut because I don't do a lot to control these things. I don't like using even organic bug Killers. I strongly believe nature will balance itself. If we interfere it messes up the balance. I'm not saying I won't spray off aphids with water, or remove squash bugs, and eggs, if it gets super bad, I may try something else, but I really hope it doesn't come to that. I wouldn't be surprised if I had stink bugs, or the like last year. I've seen the damaged leaves before. I just didn't know what it was. I didn't do anything last year, and still managed to get lots of squash, and pumpkin.
My plan is to go back in the daylight and try to remove as many eggs and bugs I can find. Hopefully the predator bugs and I can keep it under control.
I'm wondering if you have stink bug, squash bug, cucumber beetle, or other, what you do to keep them in check? Also if anyone has an idea of what night time flying wasp like creature could be, I would like to hear. Thanks

I had green aphids on my broad beans a couple of years ago. They didn't seem to be doing much harm so I left them and did a little survey of pests and predators: https://permies.com/p/1854796 . I was trying a little 'do nothing gardening' which seemed to work as last year I didn't notice them at all.... This year I have seen rather a lot of cabbage white butterfly caterpillars on my perennial kale in the tree field, so I'm going to see if 'do nothing' works for them too. I do have plenty of kale plants elsewhere, so don't mind if some get slightly tatty.

My passionfruit vines attract stinkbugs, which in turn attract assassin bugs, which look a lot like wasps but are not. I don't know about their nocturnal habits or whether you have them where you live (although you might find this interesting.... https://ucanr.edu/blog/bug-squad/article/theres-assassin-your-garden) . There are many, many kinds.  

I will say, be careful with the stinkbugs. I don't have sting allergies and work in the garden without gloves more often than I should, never have a problem. This year while pruning my passionfruit I got burned by a stinkbug so badly I still have the scar- worse than a spider bite, a big old chemical burn on my forearm. I've smashed them with my hands (and gotten the stain to prove it) countless times, but never had this happen before. I was more worried about the assassin bugs (which have a heck of a bite and can cause disease, although not generally in my region)..... but it was definitely a stinkbug, there is no confusing the smell. I will never prune those vines in short sleeves again.

I have wasps that adore hunting for Cabbage White larvae and they're way better at it than I am.

Other than squishing or relocating slugs, I too, pretty much leave the insects to sort themselves out.

Worldwide, insects are in the decline, so I try to let nature handle it, except when it's lice on my chickens, and even then, my approach is generally either watered down mild hand soap or petroleum jelly. As a prophylactic, I do use a vegetable oil on their perches and a light sprinkling of diatomaceous earth in their nest boxes.

I do think I need to find a way to put a shallow dish of water for the wild birds to drink and bathe in. If done right, it might help the insects too. I may try that approach with a few plants that the Sugar Ants insist on farming bugs on. I try to give the ants plants I don't care about to do that on, but there's one baby tree that's struggling and may need a bit of relief.

I have read wasps don't fly at night, but some hornets do, so maybe a hornet?  If it is it sounds like they may help reduce the population of eggs and baby stink bugs, but not the adults.
I may sprinkle some diatomaceous earth around the base of the affected plants, I don't think to many beneficial bugs hang out there.
Has anyone tried the soapy water trap?  You fill a pan with soapy water and shine a light in the pan. I'm thinking of trying this one. As long as I remove it in the morning, hopefully I won't kill beneficial bugs.
I also intend on looking for and removing all the eggs I can find.
As much as I would like to step back and let nature take care of the problem, the Internet has me worried this particular stink bug multiplies to fast and doesn't have the natural predator meant to keep it in check. I won't spray chemicals, I do think I need to help keep these bugs from over populating my garden.

I tried the soapy water trap, not one stink bug.  My husband thinks it may be because the light I used didn't stay on long enough?
I was out again tonight, and I started to think maybe I panicked for no reason. I haven't seen any stink bugs for a couple of nights. No sooner did I have that thought then I saw one, then another, and another.I must have gotten about 10 to 15 stink bugs. ( Thank goodness I have a lousy sense of smell, and can't smell them) I found one cluster of eggs, I just cut the leaf off and put it in the soapy water.
The plants don't really seem to be suffering from the stink bugs, far. A few holes here and there. I think I will continue to hunt them every time I water. I hope this will be enough to keep them from destroying my squash, and melons.
I saw a few bees on the squash plants. They were not flying (nothing has bothered me, besides mosquitoes since that one night. I took a picture of the stink bug, and the bee. I did a search on both, and as I figured it's a molted stink bug. The bee is a squash bee. I didn't know there was such a thing.  They won't help with my bug problems, but explains why I'm getting lost of squash, those little guys are doing the job.

I learned squash bees live on the ground, so no diatomaceous earth.
As difficult, and frustrating it is, this just drives home how important it is to not use even organic pesticides. You just don't know what you are going to kill. Sure the stink bugs might die, but so will the bees, and beneficial bugs as well. Plus I learned diatomaceous earth kills worms. I should have known that, but I just never made the connection. It's so hard to not "do" something, but often it's what is best.
I will still remove all the stink bugs I see, but at least for now, that's all I plan to do.
