The problem is they work too well. Study after study shows that they attract far more beetles than they catch. Chemical insecticides are available that kill adult beetles and many other insects as well. Two of the more common choices include carbaryl found in the product Sevin and acephate found in Orthene. Active ingredients such as these can be found in many different product names.

Unfortunately chemical controls such as these are non-selective. They are very effective in controlling pests but can kill just about any insect that comes in contact with it, including beneficials and pollinators. If you resort to these control measures, please exercise appropriate care. Be sure to apply late in the day or evening and when winds are calm to minimize the adverse impact on beneficials.

Before you make the decision to attack your beetle problem from the ground, realize that your lawn or landscape may not be the problem and grub populations may be low there.

Testing a few areas around your yard is the first step to even see if you begin a control program. The best time for this exercise is while the grubs are near the surface, during late summer and late spring. Turn it over and inspect the root area and soil below for grubs.

If you count 10 or more grubs per square, treatment is worth considering. There are a number of chemicals used to treat grubs synthetically. These can be very effective but also know that when used improperly, these and other insecticides can pose a serious hazard to wildlife, other beneficials, the environment, and people. Because of these concerns, many experts believe a better alternative for turf insect suppression are biological controls.

These methods effectively incorporate the use of bacteria, nematodes and parasites. These are ways to achieve similar results without many of the risks posed by traditional methods, including beneficial and non-targeted organisms. Although these methods may take longer to achieve the same effectiveness, they will last longer in the soil. A partial list of some of the most popular are listed here. Milky Spore : You find this product listed by its common name.

The active ingredient is the spores of a bacteria called Paenibacillus popilliae formerly Bacillus popilliae. This product can be purchased from Arbico Organics in either a powder application best for the garden or farm or as granules best for turf.

It is selective and harmless to people and other organisms. Milky Spore has been most effective in the Eastern United States.

When the grub dies, a billion or two more spores are released back into the soil where they continue to increase the population. It takes years to achieve effective suppression. The best results are achieved when used in a neighborhood-wide campaign.

During this time, other insecticides to control grubs in the soil should not be used as they can interfere with the population build-up. Bt: Bacillus thuringiensis is also a bacteria-specific to larvae and grubs of the Japanese beetle and others. It must be ingested but is then very effective.

It is also a good choice because it will not harm non-targeted organisms. This is applied like other insecticides. Particular strains of Bt proteins are host-specific, so it is important to use the strain of Bt that targets a certain pest. You may not find this readily at garden centers, however, there are online sources that offer specific Bt strains.

This strain is reportedly effective against both the adult and grub forms of Japanese, Asian, and Oriental beetles. Parasitic nematodes are probably the newest biological control method to become commercially available. In , a law was passed that made it illegal to import plants rooted in soil. Unfortunately, the failure to implement the law immediately allowed the Japanese beetle to arrive in this country.

Most entomologists agree that the beetles entered the country as grubs in soil on Japanese iris roots. In , these coppery-winged pests were first spotted in a nursery near Riverton, New Jersey, and by , eradication programs were dropped; the beetle proved to be too prolific and widespread. They have copper-colored backs, tan wings, and small white hairs lining each side of the abdomen. Japanese beetles usually feed in small groups. Prior to becoming adult beetles in June, they are 1-inch-long, white, c-shaped grubs live in the soil and feed on the roots of many plants.

Often, these grubs are a problem in lawns. They attack plants in groups, which is why damage is so severe. Although the lifecycle of the adult Japanese beetle is barely 40 days, it can cover a lot of ground. Photo Credit: Ohio State University. Japanese beetles cause leaves to appear skeletonized. Japanese beetles feed on a wide variety of flowers and crops the adult beetles attack more than different kinds of plants , but in terms of garden plants, they are especially common on roses , as well as beans , grapes , and raspberries.

Japanese beetles chew leaf tissue from between the veins, leaving a lacy skeleton. Mexican Bean Beetles can also leave foliage skeletonized, though, so be sure to identify the beetle by their appearance as well. Japanese beetles are not usually far from damaged leaves, so inspect the plant thoroughly.

Also keep an eye on the ground beneath the plant; the beetles may reflexively drop off the plant if disturbed. Japanese beetle grubs damage grass when overwintering in the soil, as they feast on the roots of lawn grasses and garden plants.

This can cause brown patches of dead or dying grass to form in the lawn, which will pull up easily thanks to the weakened roots. Fortunately, g ood horticultural practices, including watering and fertilizing, will reduce the impact of the damage caused by these beetles, but often times you simply need to get rid of them. Here are some ideas:.

Sometimes the easiest way to get rid of Japanese beetles is to pick them off the plants before they do too much damage. Unfortunately, there is no magic potion to get rid of this pest. For general preventive maintenance, experts recommend keeping your landscape healthy. Remove diseased and poorly nourished trees as well as any prematurely ripening or diseased fruits, which can attract Japanese beetles. Try these tips:. If application of these materials to plants is necessary during the bloom period, do not apply during hours when bees are visiting the flowers late morning through mid-day.

If more than just a few yard and garden plantings are to be treated, you may need to contact nearby beekeepers in advance so that they can protect their colonies.

I too sacrifice an old rose bush thats away from my other plants and that is also where I collect the bugs and destroy I regularly spray mixture of Garlic and water on those plants I want to protect It doesn't kill them but they don't like it. Let the garlic soak in a separate container for a day or so.

You can add other natural deterrents if you wish cedar leaves tomato leaves ruhbarb geranium Strain the mixture into a sprayer I chose NOT to use a trap this year. I feel that this year I have had less of a problem without the trap although I cant be certain on the numbers. My husband goes out a time or two each day and collects japanese beetles in a large yogurt container with just some water in it, no soap. Then he carries it out to our hens. My goodness, the ladies race right for him talking all the way.

He reaches into the water and scoops the beetles out, then dashes them to the ground. The ladies jump right on them and eat them all up. They love them, and look forward to their beetle treats every day during japanese beetle season.

I discovered they also love hollyhocks. This is the first time I planted them in my garden. I found a mating pair on a leaf and dumped them into soapy water. I also have little sprouts of sassafras trees and those leaves get decimated too. Don't notice any other plants getting eaten so far. I applied milky spore to my lawn in early spring and will again in the fall. We rent a condo and have a tiny garden plot out front, which we use predominantly to grow a few interesting food products like beans, tomato peppers etc.

We plant these around a few existing plants that were there before we moved in. And one of these happens to be a rose bush. I've noticed that Japanese beetles particularly love this rose bush as this article points out. But what we've also noticed, is that they love it so much they stick to it like glue and leave our food items relatively alone and continue to strip the rose bush. So I have no plans on removing that rose bush.

Even if it is attracting Japanese beetles, it's distracting them from turning our garden into a graveyard. When I purchased my house in North Jersey back in the late seventies, there was a puny, little red rose bush up against a wall. Try as I might, nothing got it to thrive. It didn't help that it was a chick magnet for every Japanese beetle in Passaic county.

It finally gave up the ghost and my J. Lo and behold, I was out early a few days ago and what should I see, but a lone beetle sitting on a peppermint stalk in all his bronzy, green glory! Now if I could have been sure that it would have been content to help eradicate the peppermint patch that is slowly taking over my front yard, I would gladly have let him stay.

However, he was dangerously close to my tomatoes, peppers and cucumbers and I wasn't sure if he would find them as tasty as my poor, lamented rose bush. Unfortunately, the story did not end happily for my little visitor. The Japanese Beetles would devour my roses and crepe myrtles every year, completely eating the crepe myrtle blooms off the plant! I did this about 2 or 3 years ago. The Japanese Beetle damage last year and this year is almost nothing. I see an occasional beetle, but little to no damage on the plants, and no clusters of beetles feeding on the blooms.

Fingers crossed that it continues to work for years to come, but so far so good! While it was not cheap, it will be well worth the investment if it lasts for the 10 years or so that it should. I chuckled at your suggestion to hand pick them and throw them into a paper cup with soapy water. There is something very satisfying in flinging those nasty little bugs that ruined my roses, into the soapy water and seeing them try to swim.

The best solution that I have found to help decrease the population of Japanese Beetles are the bag traps.
