This is my most hated garden rival. Roses, Primroses, fruit trees, berry bushes, grapevines, asparagus ferns, they go from one to the next.

I've tried treating the lawn with a grub killer, but my lawn is just too big for it to have a measurable effect.

This beetle is total devastation to any garden in my area. It is so wide spread that you can not even find beetle bags in any of the stores in my area. I use the beetle bags back in the wooded part of my garden to try and keep them from my garden plants. It draws a lot of beetles because of the harmone disc w/the bag. I still have my garden eaten. The only thing my husband & I found that can help get rid of this awful beetle is to use Seven dust or spray, using insecticidal soap does not work. I hate to use chemicals, as we feed the birds & critters that come into our garden. Does anyone know of something safer I can use? I have a 1/3rd of an acre of gardens, so it is impossible to pick them off of the plants and drown them in soap. We have also used the grub insecticide in our lawn and garden and still to no avail.

I have been waging warfare on Japanese Beetles for years now. They are the BIGGEST problem in my garden ... mostly because I have a ton of roses. They also love other plants as well and have been feasting lately on my Canna Lilly plants.
I have tried beetle bags in the past, but it made the problem MUCH worse. I have been told by other gardeners and have read on other web sites that these bags cause more of a problem than they solve, however, some people have much luck with them. I don't recommend them though.
I have also tried chemical sprays and more environmentally friendly sprays, They work for a short time, but still the beetles come. I have also tried grub killers in my lawn in both fall and spring. I believe it has helped somewhat, but they are still here.
Since I have waged war on these nasty bugs, I have done as much research as I can. I like things that are safe for the environment ... so this year and next I will be trying two things. First, I will be using Milky Spore Treatment. This is applied to areas in a grid like pattern. This treatment is supposed to last for 10 years or more, increasing as time goes by. It kills the grubs in the larvae stage. I'm hoping my neighbors will try it as well, so we will have our areas covered!! This is my fall treatment. :)
Second, I will be buying beneficial nematodes to add to the garden areas. This is applied by mixing with water and spraying on the garden. I will be using this in the spring when the soil warms. The nematodes are supposed to kill the larvae as well, but will not harm beneficial insects.
This is my plan, we will see what happens, can let you all know next year!!

Maybe the critters ate themselves to death. I haven't seen any in two-three weeks.
I like the idea of a "bird garden". In fact, we have had so many Robins and Blue Jays around this year, they may be the solution of the JB problem. Me thinks me will place a couple of bird baths out to intice more birds next year.

This is the most horrible, destructive bug ever! They were even attacking my blue spruce, black spruce and arborvitae! The only thing I have not had eaten by them was the leaves on our 2 oak trees. Every pesticide that will kill them, washes off in rain or dew dilutes it so it is very expensive due to constant reapplications. These nasty insects appear to come in droves from the soybean fields of farmers to the south of our home, starting in late June and are here until after the 1st hard frost. I read that you are suppose to apply nemotodes and milky spore to your lawn in early spring before the grass turns green to kill there eggs and larvae, so I am going to try it this spring. Will keep you posted on wether it works or not.

Encountered this Evil Creature for the first time in July 2005, munching my crape myrtles. After googling, fixed soapy solution in a large yogurt container and spent the next week-10 days going out multiple times a day and knocking every one I could find into the soup (hundreds by the time it was over). Trees were young enough I could still reach nearly to the top, and I got very good at sneaking up on the Evil Creatures. (I work from home, and some days it doesn't take much justify taking a break.) With trepidation, set out a couple of the bag traps also, and caught hundreds. When there was a breeze, I saw fewer beetles in the trees and more in the traps; I'd been worried that the traps would just pull in more from surrounding n'hood, but don't think that happened. Patrolled the rest of the premises vigilantly, but only found a few on some four o'clocks in the backyard; they did not find my tomatoes & peppers (30 feet away), or daylilies or hostas. (Too bad they don't eat privet, English ivy, or bamboo.)
The next year they showed up again but in far fewer numbers. Set traps and caught lots; trees too tall to hand pick much.
Those crape myrtles are one of my few successes in seven years of Horticulture Gone Terribly Wrong, so I'm a little worried about what this summer might bring.

My understanding is that it takes a couple of years for it to really establish.
This year I'm going to try and cover the fruit trees with floating "row cover" to keep them off during fruiting. I guess they aren't suppose to be able to climb up under the netting. We'll see.

I moved to Gainesville, GA in 1971. I had never seen a JB before then. I was amazed! Anyway, I had been getting Organic Garden magazine and I saw an ad for Milky Spore. Folkes, this is the answer to your problems. In those days I was quite broke and so I could only buy a little bit. But I placed it as far as I could go and I used a larger grid than was recommended. The first year there was not much difference. However, 25 years later that property was JB free! Also, something else I have noted. When I moved to my present property I brought several plants with me. I have not had a JB invasion yet, altho I do notice a few here and there. Don't worry about your neighbors buying it. It will spread. Not fast, but it will spread. Let's face it, just how fast can a little grub travel underground. And he has to travel to spread the spore. They took Milky Spore off the market for awhile and I kept inquiring "why"? No one could tell me. I even called Organic Gardening AND the local ag. people. No luck. Finally, I saw it again, years later! One person told me they took it off the market because it didn't work. Well, I believe they took it off the market because it worked TOO well. Also, I have only been able to find it in feed stores. Your local Home Depot and Lowes does not carry it.

They're here. The awful insects have arrived to munch on Raleigh NC, harkening the impending summer season and battling me as I fight for the salvation of my beautiful hardy hibiscus. I have many different plants in my garden, but for whatever reason they love to destroy my very favorite hibiscus plant. Last year (my 2nd yr tending to my current garden) they also attacked my climbing hydrangea, completly skeletonizing it before I finally broke down and sprayed Sevin on it (the only chemicals I had used thus far in my modest, though lovely, garden had been some occasional Miracle Grow). Before the Sevin I had tried the beetle traps but they weren't working quickly enough. The awful JBs left instantly as soon as the Sevin was introduced, though my Climbing Hydrangea was pretty much done for the season.
My beautiful wine-colored hardy hibiscus has been thriving in a damp area of my yard; just last week I counted appx 60 buds on it. Each bloom lasts a day, and is almost the size of my head. Last week I started noticing my dreaded enemy showing up on my beloved shrub. The JBs love the leaves in particular-- just today I watched incredulously as they did rather unholy things on the broad leaves before I knocked them to the ground and crushed them mercilessly after spraying them as they basked on the leaves. I introduced chemicals earlier this year; the Sevin is definitely helping. I've been having to reapply frequently as it seems to easily wash off when it rains.
If I can recall correctly from last year I think I remember the JBs were gone after a few weeks of terrorizing my garden. I'm hoping to put up the good fight until they find some other poor garden to destroy.

Yes, like everyone else, the beetles have invaded en masse'. Last year was our first experience with them, having moved the nursery up from Florida (that has every other bug in the world... except these), and we were surprised how selective they seemed to be... but they did cause an incredible amount of damage.
We learned from last year, and to our surprise, they have hit almost everything in the beds and containers, even oaks and some of the conifers...
We have a large bird and frog population, and try not to use too many chemicals, so we have a control strategy for the invaders. Our strategy is firstly to squish them as we patrol the grounds. Then when there are concentrations of beetles, we spot-spray with a mix of Sevin and Malathion. The Sevin works well, but adding the Malathion helps to keep other bugs down, and adds a disagreeable taste for the deer that sneak up on us...
We also have several of the bug/scent traps set up in key locations. These work very well for us, and we change the bags every couple of days. The beetles are suppose to be drawn to the traps from over a quarter acre away or whatever, and thats ok with us. The areas around the traps tend to collect the eaters, so our spot-spraying helps there.
Now last year, at mid-infestation, we were filling two bags a day! This year, we havent filled a single bag, but the bags do need to be changed and kept clean and fresh or it deters the beetles. We think our control program last year has lessened the beetle population for this season, and with the combination approach, we are somewhat optimistic.
A friend of our is trying the Milky Spores, and we might as well. Someone mentioned friendly menatodes... we will look into that as well.
Hope our notes helps...

I used beetle traps but felt they attracted more than they trapped. Our Extension office and Master Gardener instructor recommended against using them unless you could locate them in your neighbors yard. Last July I applied grubX to as large an area as I could afford. Also not using traps this year. So far beetle activity is very low in the areas that had GrubX applied. I spray with Sevin weekly and started as soon as I saw the first beetle. Also hand pick them and drop them in soapy water. I will try the soapy water spray. I fear the battle is just beginning.

We tried two of the traps a couple of years ago and I must say that they provided fun for the entire family. Every evening, we would all go out to see how many JBs we had.

This is my 3rd summer tending my garden and the 1st summer that the JBs have not ravaged everything from roses to cosmos to yarrow. In fact, they're so few in number now that it's tempting to forget about them - but I continue to dispatch every one that I find! I've not known whether to attribute the low numbers to unfavorable weather conditions for the grubs in the last year (were they? I've no idea what the grubs need) or to my eradication efforts last year and my ongoing obsession with killing every grub I came across in the course of removing the lawn and digging and planting a cottage garden. (I fed every grub to my birds - yum!) I applied milky spore to my garden in March this year, though my nurseryman told me that m/s is most effective in the period after the eggs hatch and the larvae feed heavily (August until freezing). I found emerging JBs in the soil this year in mid-June, and by late June was going on patrol with soapy water 2-3x a day ... but I noticed that the beetles this year are very small, half the size of last year's beetles. After 10 days of soapy water patrol, I am finding only 3-4 beetles per day in the garden. I am cautiously optimistic that my efforts have paid off.
On the other hand, since neither of my neighbors treated their gardens and both have lawns (whose roots are just what grubs like best, no?), I would think the beetles would have carried on as they did every year and the low number of smaller beetles this year is a result of those unfavorable weather conditions I was wondering about. I will probably offer to treat my neighbors' gardens next month with milky spore ... a worthwhile investment when I consider how much $$$ I have poured into the plants in my garden!
I hung a pheromone trap at the far end of the garden last year and even though it was vile it did draw them in and away from my prized plantings. I also used Sevin on one rose bush last year and it certainly worked, but I am worried about the disappearance of honeybees and CCD (colony collapse disorder) and want to make things as easy as possible for these creatures. My garden this year has been a haven for bees of all kinds, including hundreds of honeybees, and applying Sevin is simply not an option.
Finally, has anyone had definite success with the nematodes? I've heard that applying both nematodes and milky spore is counter-productive, since the m/s is spread by the grubs and the nematodes kill the grubs before they have time to travel. Don't know for a fact that this is so, but if anyone out there knows about this - do tell!

Either that, or empty your bag, and find a way of disposing of the beetles, without any of them flying away.

I've lived in my current home only a year, and last summer the Japanese Beetles weren't too bad, only damaging the blackberries and some of my roses. I'm not sure how useful this tip is for most people but my Jack Russell Terrier loves the critters and eats them by the hundreds! I let her loose in my rose garden and she stripped them bare. She patrols the lawn religiously and devours any beetle she finds, and in fact if I call her over to "find the bugs", she knows exactly what she's looking for!

I have battled this little bugger for years and have found that the traps work the best in conjucnction with spraying. So far this year, actually a week or so since they appeared I have bagged over ten quarts of them. My flowers have been virtually untouched. It doesn't matter where they come from or if I'm attracting them...if they go into the trap that's less to lay eggs and produce more larvae. I just ordered two more. Fresh bait works the best each year. I tried Milky Spore years ago and it was ust a waste of money...IMHO.

I dont know what to do...i am afraid to use chemicals in my yard because i have 2 young children & 2 dogs...i use the beetle bug traps...the ones with the bags and the little disc that draws them in and it worked great last summer but this summer it doesnt seem to be helping at all....i cant take the kids outside because they swarm them and the dogs. We cant even use the pool, play in the sand box or on the swingset....its horrible....any suggestions or anyone know how long before these things go away!!!??

Last year, 2008 was HORRIBLE. These critters are really the bane of one's existence. I gave up last year. Here in
Ithaca, NY, you can start looking out for them about June 30, but they tend to disappear by the second week of Aug. I hear milky spore really works, but you have to give it 3-4 years. I guess the multi-pronged approach is the best answer ...and pray real hard that they will have mercy on us.

For years we've had horrible infestations of these beetles. Last fall I applied Milky Spore to the entire property and also drenched beneficial nematodes into the soil. This year there were virtually no beetles here and I thought that the treatments had been effective. That is, until friends who did nothing to their properties told me that they had no beetles this year either.

This Nasty little creature has destroyed my beans. I have learned to NOT use the trap. It only makes it worse. The only thing I could do is try to kill them individually when I saw them on the plant. I pick them off individually and crush them, or when there are a lot of them, I get a container of water with some dish soap and just nock them into the container and let them drown. They turned my leaves into spider webs.

I kill grubs in the ground, but they just fly in from elsewhere. I use systemic insectide granules on my roses. It works wonderfully for the foliage, but not the blooms. Picking them off is helpful at some times, but hopeless when they really infest. I cut some flowers at budstage and bring them inside to enjoy. The rose'The Fawn' doesn't get attacked quite as badly as most of the others. 'Double Knock' out does very well.

I have used everything they make, and then I found " Bayer" it's a systemic you treat the ground with before they come out, grant it I have alot of areas and cannot use it everywhere, but in my beds that they can strip in one day I use it and the bag a bugs work great around other areas. This year I found they no longer make the bags, it's a green plastic cylinder with the same yellow holder for the scent but these are so much better as they have holes and let the rain out and not as much of a smell!! Put at least 10ft. from plants as they will be drawn to it instead of the plant. Now you will still find some on plants but if you could only see how many bugs are in 5 bag a bug containers you wouldn't believe!!

My "thundercloud purple leaf plum" tree is covered with these nasty little beetles! I have 2 of these trees! The trees are only 2 years old so they are small enough to maybe manage for now. They have chewed through nearly 1/2 of the leaves.
I gave these little guys a nice morning bath in my soap pail. I got maybe 200 of them in about 15 minutes. I'm trying to stay away from the chemicals. I feel better knowing that I put some to rest.

Can anyone give me suggestions on how to get rid of these. Every year they devour my cherry tree, roses, berry bushes, and all trees around, even my butterfly bush. I am trying to stay chemical free in my yard, but I'm at wits end. I have never hated any bug like these. I will do any thing to destroy them. They couldn't possibly be good for anything.

yes these bugs have destroyed my marigolds. the neighbor who grows roses from across the street put out those bags and she was filling them twice a day. i didnt start seeing them until those bags were put out and now i dont have a single bloom left. im hoping next year that they stay away.

This may help some with smaller gardens....
1.) place a white bucket or milk jug with water in it and ripe fruit like banana peels and mango in it as a lure under favorite shrub or tree. Beetles can't fly out of the milk jug once inside but add a small amount of dish soap to an open white bucket. These won't draw beetles from miles around like the pheromone traps do.
2.)One of the Universities recommended [instead of using commercial pheromone traps which draw in more beetles than they can kill] to place a pheromone trap "over" a basin filled with soapy water with a "white bottom". [use a white plastic bag to line the basin] .Some people said the pools fill with beetles which drown in the soap. Only problem with this second method is it will draw Japanese Beetles into your yard from neighboring areas however it will kill more beetles so fewer are laying eggs every three days. [I just wonder if they will sink or climb on top of each other]
3.) In early morning, before sunrise you can spread a sheet under small trees or shrubs and shake the plant. Japanese Beetles will fall down onto the sheet which you then gather up and dump into a bag.

Some years are much worse than others where I live. With most pests, there are completely nonchemical things that can be done to get rid of them. I don't use any chemical fertilizers, herbicides, or pesticides, only completely natural methods. However, these little buggers defy virtually every method I attempt on them. Any ideas?
