This is the best method I have come across so far, coupled with milky spore.

Wow! What a great idea. And it does make sense - I would avoid an area also if I saw or smelled dead bodies of my own species! Rolling on the floor laughing Thanks for the tip!

Interesting idea!

I would like to know if anyone has tried this and what level of success you've had keeping the beetles away.

I also wonder if this idea could be applied to other destructive bugs as well?

I've read about this but wasn't sure whether it really worked. Thanks for providing your experience!

I've tried spraying "blender beetle" with mixed success... the decay aspect of your method might be part of the trick! This also seems a little less gross than preparing blender beetle tea. I'm also glad to know you could not detect the scent, as those bags of beetles from the traps do get really rank.
I'm learning to dance in the rain. Thank you, Sally & Chris.

We got hundreds of JB on our cherry tree. Will try this.
BTW, your climbing rose looks lovely. Very pretty on the white fence.

May have to tweak things down here and add mosquito repellent duks to the water. West Nile Virus is a problem down here.

Mosquitos would be a problem here too. But you leave the lid on the dead bugs and let them rot basically in the water?? And the scent floats up and the bugs can smell it??

Tried this method last year, the Japanese Beetles seemed particularly fond of my Cannas, I kept the soapy beetle mixture near the base of the plant. Still got Beetles attacking the Cannas, but not in great numbers...thinking it probably helped!

crawgarden - Welcome! to NGA! Glad to hear that someone has tried this and has seen a difference. Definitely worth trying, IMHO. Thumbs up

I sprayed dead beetle juice on my roses and the beetles stopped coming. I collected the beetles in a glass-wide-mouth-bottle half filled with soapy water. After they died, I put the water in a spray bottle and sprayed the roses. Replenish the water and soap in the glass jar to flip the beetles into it to make some more of the water to spray. I did not use blend the beetles. Let them die from drowning in soapy water. It may help too that no one else in the neighborhood have a lot of roses.

Your roses are beautiful, Buttonwood. Your method is easier. If the beetles come again, I will use your method. Thank you---

I will definitely give this a try. I spend a lot of time handpicking and drowning these pests in soapy water. Their main (but not only) target in my garden are my climbing hydrangeas. Hopefully they can smell the decay up 6-7 feet!
