I feel like I have a lot input on these due to last years' infestation. For hard infestations Treat all areas of property with lambda cyhalothrin, a common food/garden safe brand (commonly used on tobacco too) is spectracide triazicide. Also can dowse plant with this liquid but takes a day or two to effectively kill off insects/larva (if applied to broken soil) (Don't apply within 4 weeks of harvest). These beetles will flock, nab and nick on you but don't seem to bite, they seem to be attracted to light, and any food/crop of the nightshade family.
Personally, I sprayed the boundaries of my property as well as out buildings, the house and any broken ground that might house larva. Make sure your pets are treated for their normal diseases as these beetles can carry disease.
I lost a good 3 total plants do to their eating habits.
From what I've found, squishing these bugs you get a nice pop, shriek and hiss, and this also attracts more bugs to feed of the dead bugs, and feed off your lovely crop. Good luck with any infestation you have...it can be a pain for that 5 weeks.
