In 2019 and 2020 we had the Colorado potato bug. In 2019, someone sprayed them heavily with Sevin and we lost the bees with them.
This year we sprayed with a dawn soapy mixture.
But the best way is to get....say a 10" x 10"x 2" (whatever) plastic container with a little soapy water and flick them into the water. Quick and easy.
Unfortunately, and for the first time ever, I have “tomato fruitworms” aka “army worms” eating holes in my gorgeous tomatoes. I’ve had to throw away some good ones; however, the majority are doing ok. I was going to spray with the insecticidal soap recipe (bottom of article), but haven’t done it yet. I use both Dawn & Dr. Bronner’s in the house, so either one makes a great insecticidal soap.
I pick my tomatoes (and have been doing it for a couple of years) when they get the first blush of color, then I let them ripen up on the counter in the kitchen, This saves a lot of bird/insect damage that happens when tomatoes ripen on the vine. They are still delicious and look fantastic - beautiful, unblemished red color.

BTW, I’ve seen two worms halfway in holes & it looks just like the one in the pictures, so I know my diagnosis of the problem is the correct one!
