I use a vegetable spray that it says is safe to be used right up to the day of picking. I believe it's called Sevin. (I'll check that and make a correction of needed). It comes in a red spray bottle. It kills the beetle within minutes. We haven't had a serious infestation yet, so I'm hoping it will be a better summer than last year.
I have seen four o'clocks at both Home Depot and Lowe's, as well as smaller local nurseries in my area here in the Piedmont of NC. I saw them early in the Spring, however, so I wonder if they aren't a perennial that should be planted then? You can also find seeds for four o'clocks, too, but as to whether there are any of either left, I guess, depends upon how well they may have sold earlier.
I am most happy to learn that Japanese beetles dislike the things -- very nice to know, and would make a grand addition to the beds in a yard. They are sweet little blooms, to boot!
When you say 'no' chemicals does this mean you cannot even use a systemic product like Bayer's Rose & Flower treatment? It is a combination fertilizer/pesticide/herbicide that works wonders in my flower garden, and on my roses, and it deters Japanese beetles. Of course, being systemic, you have to allow time for it to get into the plant, and a beetle to eat a little of the plant before it kills the beetle, or other pest.
I have had great success with the Bayer product for mildew and the beetles, as well as other bugs on other flowers, too. Comes in a blue bottle, and is a little expensive, but it doesn't take much, and I get several applications over the course of the summer -- you apply it with a watering can every 4-6 weeks. I prefer the liquid that you mix with water, to the granules that you sprinkle on the ground, but both work.
Aside from being voracious, destructive things, those little Japanese beetles are just plain creepy.
I too have always had good results from using that Bayer Systemic product---here in NC and in CA too. Besides using for my roses I even put it on my Weeping Cherry tree as the Japanese Beetles seem to love that too. So far so good.
What about the BAG A BUG? That bag that is on a stick that they all flock to? my neighbors swear by it.
Let your neighbors use the Bag a Bug. The beetles are attracted to the Bag a Bug and you will end up with hundreds of beetles in your yard. Have your neighbors down the road put up a few extra traps to help you keep them out of your yard.

I don't know, last year I lost my topiary to the darn pests... I think they liked that and my favoirte bush that has the prettiest white flowers on it... I had to save it by cutting about 90% of it off... they seemed to like them better than the bags on either side of my house... but the neighbors had no damage to their plants... I am going to buy the bags at the first sine of trouble myself...
I use Bayer Rose & Flower spray...it kills them right away and lasts a week...The active ingredient is Immocloped ( prob. not spelled right)...It's the only thing that has ever worked for me. :
skbs...do you have any yet this year???I have seen 1 so far...usually the 4th of July they make their debut here!!
They are here in NC! Hubbie was out mowing the lawn yesterday and found a ton of them on my grape vines and Oak tree! Still...it seems the Bayer systemic is working on my Rose bushes and Weeping Cherry tree. Maybe I'll put some of that on the Oak tree too. I can't see where it could hurt!!
You can also spray the plants with liquid Sevin. There are some that you hook right up to the hose. You must be consistent, and diligent, however, spraying with the Sevin, and it just gets too hot for me. Much easier to use the Bayer product, says the occasionally 'lazy gardener' me.
Check the label on the Bayer product for the oak, cynwldkat.
