My friend Patrice, who owns La Société des Plantes, a small seed co from Quebec, tells me he uses henbane, Hyoscyamus niger, to trap Colorado Potato Beetles.
Has anybody done this here?. He says they even prefer them to eggplants, who apparently are the CPB favorite crop.
A lot of people say that, but here, I had hundreds of eggplants planted last season and they saw few cpb, as opposed to my taters... I never had much of a cpb problems in eggplants in all those years of gardening, although they were visited.

He uses Henbane as a bait, and then what? Tosses/burns the Henbane?
I hate potato bugs with a passion. hehe A farmer not far from me uses lime sprinkled on the potato foliage to deter CPB.

Henbane is very highly poisonus...so he does not eat it for sure. I KNOW i would pick it and burn it...

I thought maybe the beetles ate it & then died from consuming it. lol

Well I knew Henbane was poisonous. hehe Just wondered what he did with it after. Does he ever have to replant the Henbane or is it successful the first time? Does he have any similar suggestions for earwigs? I hate those things too. They destroyed my fall crop of cabbages last year. Sorry to go off topic. But as I don't speak French yet I thought maybe you could pick his brain for me.

I use chinese lantern as a trap crop. It comes up early and they seem to flock to it. I have seen a CPB once on a potato and ... don't think I've seen one yet on a tomato or eggplant but I"ve seen lots on the chinese lantern.

I'm trying horseradish in pots at the corners of the plots. I have the "mother" plant in a large container in front of the house. I dug it out sorta, and whacked off a large hunk of the main part of the root. Then I divided that chunk into 4 pieces and stuck it in the pots filled with my regular potting formula. I was a tad concerned at first cause all the leaves keeled over... but I think you can see in the photo that new leaves are already coming on and it's only been about 3 or 4 days. As for the CPB, I think it's to soon to say for certain. Before the horseradish, we killed a few dozen over a 3 day period. I did not find any the day of the photos, but I did find some eggs: Today I found 2 more egg deposits that were clearly at least a day or two old, but again, no beetles. I'll be sure to post future observations.
