4 years ago I put in our first garden here then I had to leave it with hubby. He had major invasion of bugs. He sprayed them but still stripped plants overnight of all foliage. Next year I saw them critters and could literally herd them. They swooped around the yard like birds in the sky all going right and left. Amazing. Was super dry year and could see them and chase herd them. Put out powder barriers and hubby sprayed. I finally too shop vac to them and the new invasive pests coming to visit. I had seen a praying mantis so didn't want to spray. Shop vac worked good. Chased them with it sucking up all I could. So last year all I used was shop vac. Worked a charm. This year so way way less pests!! No I also sprayed out benificial nematodes
I shop vac'd a whole wasp nest last week - the nest got sucked up along with the wasps. I put some soapy water in the bottom of the vac and dumped the whole lot on the compost heap an hour or so later after they had all drowned.
Not as fast as spraying, and there were a few stragglers, but it was satisfying
