Do NOT get the bait bags. It will only attract more of the buggers. Instead, you can use their own defense mechanism against them.
If the bugs feel threatened they will just drop off whatever leaf they are on. So get yourself a small bucket (around 3 gallons) and put a few cups of water and dish soap in the bottom. In the evening while they are chilling out, give the plants a light spray of water from the hose. That will stop them from flying off. Then take your bucket of soapy water, place it under the leaves the bugs are on, and bonk the leaf with a stick. The bugs will fall off into the water and drown.
Do this for a few evenings and it should take care of the worst of your problem. You’ll have to do this again the next year to take care of the grubs already in the soil. After that you should only need occasional touchups.
