Grumbling

Do they like Smoke Bushes? I have some roses and crepe myrtle and they love to eat them up. Someone gave me a smoke bush, but then I got to thinking I don't want to plant anymore beetle attractors. I super hate these bugs. alot.

According to this article in the Journal of Arboriculture, which lists woody plants and their susceptibility, feeding on Cotinus coggygria is only occasional:

I have virtually no Japanese beetles in my yard. Used milky spore and nematodes for years, and NO traps.

do they traps work? I have heard they attract even more, but then after a few years of that, I would think it would reduce their numbers substantially. A female probably lays a jillion eggs so I figure every one that is lured is that many less later on?

I have a huge yard so using milky spore would likely not work for me? Also my neighbors all have large yards and they won't use it anyway. Plus that stuff is pricey if you are doing a very large area.

You would want to put the traps as far from your plants as you can, that way the traps take the beetles away from your yard. If you put them near your plants it will attract the beetles to your plants, exactly what you do not want.

The end of my back yard is probably 100 feet from my plants. Do you think that is far enough? I have a large yard.

Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.

well I actually do not have hours ea day for 6 wks to pick the off by hand and drop them in soapy water Blinking I usually spray w a weak sevin solution, but try to spray foliage and not blooms as much as I can. I do have lots of sages and mints, ect that the bees here like, they are not intersted as much in my roses or daylilies anyway. I do not spray anything they are not actively eating.

Japanese Beetle Traps attract them. Many are attracted but not caught. Give traps to your neighbors. Then you won't have any. LOL!
