If you use catnip as a repellent, won't they also be an attractor for cats to come and roll in your squares???

I suppose they could be. The plastic fork trick works for that, as does having a territorial cat that isn't affected by catnip (about 15% of cats aren't.)

I planted a late garden on Aug 15th. I had particularly good luck with bush beans, and broccoli/cauliflower (they were under row covers).

Started my own germ warfare: got the milky spore (pellets) spread before we had a nice rain, so hopefully those spores are doing their job infecting the grubs.

I know that will take some time (a couple of years) to be greatly effective, however, so I'm still wondering about how to handle the beetles that will come this year.

Gotta admit that I can't imagine why any companion plants will work to keep the JB's away from pole beans which are many feet above the ground and far away from the "companions." Those beetles don't have any problem bypassing their less favorite treats in order to chomp down on the beans (or roses, or crepe myrtles, or....). I have put tulle over much of my garden this year, but I don't know if that will work on the trellis.

Tom or Airdoc, in the same way, how does milky spore keep them off a pole bean?

I do love the point that MS takes care of the grubs in the dirt!

Milky spore kills Japanese Beetles in the larva stage. After they have emerged and become flying bugs, its too late. But the MS lasts for years, and will eventually kill all those suckers before they become adult bugs.

Are these JB grubs the same thing referred to as chinch bugs on the packaging of lawn insecticides?

chinch bugs

Don't know. I don't use lawn insecticides. The nice thing about Milky Spore is that is all organic. It only affects grubs in the ground.


"Milky Spore is a bacterium, Bacillus popillae, which is lethal primarily for Japanese beetle grubs. Once applied, it can remain in the soil for many years. In warm climates, good control of the Japanese beetle can occur in one to three years; in cooler climates, three to five years.
The life cycle of the Japanese beetle includes the immature beetle, called a grub. It stays in the soil of your yard and garden, feeding on the roots of your grass and other vegetation. Once Milky Spore is applied, the grubs ingest it as a normal part of their feeding. The more spores are in the area, the greater the chance of infection. Each infected grub dies within approximately 3 weeks and releases new spores.
Milky Spore is not affected by freezing or other adverse environmental conditions. Milky Spore is not generally affected by most fertilizers, pesticides, herbicides and other lawn chemicals.
Milky Spore Powder is considered harmless to food crops. It may be used in gardens, around pools and near wells. Milky Spore is not known to affect pets, beneficial insects, fish, bees, birds, other animals, plants, or man......."

Michelle- I don't think so.

Here is a chinch bug and here is a Japanese beetle.

Last year I saw several Japanese beetles and a milkweed bug (apparently a type of chinch bug) on my beans so I do think they can coexist in the same area at least in my neck of the woods. Smile

Thanks; I recognize the chinch bug as something my son thinks is pretty...but not sure I've seen Japanese beetles around here.

I have been battling against June Bugs and Japanese Beetles for years. June bugs are the worst, they come down the chiney and attack me whilst I watch tv! I have taken to blocking the fireplace with black trash bags and duct tape for a few weeks each year.

A few years back I applied beneficial milky spore all over the rear yard. For my efforts I saw a significant reduction that year and even less last summer. I am going to order some more this week as I cant find locally this year. I am hoping that they will find and destroy the grubs and army worms I uncovered whilst digging last week.

Good luck !

Thanks Kay. I was about to ask why you'd want to treat such a wide area of the yard.

Thanks to you too Tom for the explanation!

Milky spore can be bought at Lowes Very Happy

Nemattack or nemaseek you need to order online.

Most hardware stores will have a Japanese Beetle trap. These are ok if you have nothing else but dont rely on it to work.

follow up question..

Post  rjeverett on 7/25/2012, 5:43 pm

So, the adults are gone around my area, haven't seen one in weeks, today however I found two grubs around my pepper and toms..which may explain why my poor little peppers have been just sitting around not producing anything. Needless to say I'll be grabbing me some milky spore this week!
My question is actually about the effect the milky spore might also have on vine borers that may find their way into my beds. Will the ms work on them as well or do they not feed once they're down there??

As far as I know, milky spore disease effects Japanese beetles only. It also can take a few seasons to be quite effective.

Well, mixed results at my garden this year. I did use the milky spore and saw a dramatic reduction in the numbers of JB's this year. I also waited and planted the pole beans late, using seeds I kept from last year. NONE sprouted. Sad

Oh, well, live and learn. Next year, I won't try to use saved seeds, despite Mel's advice. Some of my saved seeds worked for other plants, but many did not.

Judging from the small number of Japanese beetles in my trap, it didn't work very well. Altho I don't see a lot of beetles in general this year. Much less than last year. I wonder if the chickens eat the grubs, or if the grubs are too deep in the soil...

Less Japanese Beetles

Post  Bren Ford on 8/4/2012, 9:02 pm

I did the Milky Spore application a couple of years ago. I have considerably less beetles this year. The ones I do have are enjoying my blueberry bushes, hibiscus, asparagus, trailing geraniums, and one of my clematises. I will add more Milky Spore this fall in hopes of iradicating these hungry things. I also keep a coffee can w/ rubbing alcohol, so when I see them, I put them in there. I wonder if they go in cylces?

Yeppers- it's time for these nasty bugs again and they are everywhere!!! affraid
We have quite the grub problem in our yard and had the front yard treated last year to help us actually grow some grass there. However, I'm sure the back yard was equally infested along with all of our neighbors. So, I'm not confident that investing in milky spore for my yard and garden is going to make enough of a difference to protect the huge damage the June bugs are doing to my garden now and in the future since we are in a subdivision w/ close houses. I know that nematodes are beneficial to kill off other bad soil bugs too, so might try that in the garden where it stays moist enough to keep them working against grubs but what about the adults.

I found an idea about putting a light secured to the top of a bucket w/ soapy water in the bottom. I think that's a semi-decent idea but am looking for additional organic/homemade ways to save my garden from these guys. study idk

Assassin bugs LOVE Japanese beetles, and have just about eliminated them here. They used to tear up my grapes something awful.

In the spring, when I find a new hatch of assassin bugs, I separate them and spread them around the garden, because the first thing the little ones do is eat each other. By spreading them around, they will start their diet on aphids, mites and other small insects, moving on up to caterpillars, flies and Japanese beetles as they mature.

hmmmm, I think one of those beetles is living in the planter of my avocado tree. I was watering it the other day and it crawled out. At first I thought it was a cockroach, but it wasn't. I didn't kill it because I wasn't sure what it was, and I don't want to indiscriminately kill bugs, because I might make the mistake of killing something good. I guess I will smash it next time I see it. Haven't seen any assassin bugs though, unfortunately.
