How To Get Rid Of Japanese Beetles

Japanese beetles are insects whose origin are often attributed to Japan, but are readily found and thrive in New Jersey, East of Mississippi river, among other areas. They are also known to have infested Wisconsin, Oregon and California. These insects feed on leaves and roots of 300 varieties of plants. These can readily multiply and can easily cause major damage to landscape and any other green regions. Given that they usually have an 8 week feeding period, they need to be rid of as soon as possible. 


  1. Cover the plants

Place large sheets of row covers over the plants and all green areas to prevent the Japanese beetles from causing destruction by chewing off the leaves. Particularly, in seasons when garden beetles are the most active, cover the plants to stop them from causing destruction. This will force the Japanese beetles to land on the row covers instead of landing on the plants.

  1. Picking off the beetles

The less desirable method is to manually remove the Japanese beetles with your hands. This is usually more effective when the numbers of Japanese beetles are less. Before carrying out this task, prepare a solution of dishwashing soap detergent and water. Once the hand beetles are picked, they should be thrown into this mixture. This solution will kill the Japanese beetles immediately. During those 8 weeks’ feeding period, this method is useful, particularly after in the morning.

Early in the morning, when the insects are most active, a drop cloth could be used to shake of the leaves covered with Japanese Beetles and put directly into a bucket filled with dishwashing liquid and water.

  1. Guinea fowl for a pet

There are few birds like Guinea Fowl that love to feed of bugs and insects like the Japanese beetles. These birds love to eat as many Japanese beetles and white grubs as they can. Keeping as many of these birds in your garden will be beneficial as they will keep the plants free of Japanese beetles. However, they cannot reach taller height plant, for which perhaps covering them will be most suitable.

  1. Plant a Neem Tree

Neem leaves have natural insecticidal and astringent properties. One of the uses is to kill off Japanese beetles. The Neem essence and oil can be used in the form of spray or essential oil. Applying the Neem oil along with potassium bicarbonate serves as an organic insecticide. These are very useful in removing Japanese beetles from roses. Once the insect ingests the oil it passes it on to the eggs. These eggs when hatched get affected by the Neem spray; hence, curtailing the lifecycle of the japans beetles and its population.

  1. Tricky Geraniums

Growing fields of beautiful geranium attract the Japanese beetles. They find the plant attractive and tasty but once the insects have fed of the geraniums, it has some serious adverse effects. It makes the Japanese beetles dizzy and cause them fall on the ground. The moment they faint, they can be thrown into dishwashing solution or sprayed with Neem oil or some other insecticide.

  1. Insecticides

Insecticides are a great method of getting rid of Japanese beetles and keeping them away from your precious plants. Solutions Pest & Lawn has a number of great products which can effectively neutralize japanese beetles. One of our best insecticide recommendations to control Japanese is liquid treatment with a product called Tempo SC Ultra.

The residual of this product will keep new beetles away from the plant for up to a week forcing them to go elsewhere. It will provide quick knockdown as well so current populations will leave as you treat. To get the spray to work as well as it can, we recommend mixing the product with a surfactant. Surfactants help the chemical to stick to plant leaves, stems and a lot more of the plant than just what you spray. When treating, be sure to have your sprayer set with a wide spray pattern during the application. We have several sprayers which will work for this job and the better the coverage, the better the results

Another great suggestion is Cyonara Lawn & Garden RTU. It comes ready to use. Simply hook it up to your hose and you can get right to work. Lasty you can use either granules or dusts which you can spread on your lawn to take care of Japanese beetles. Our recommendations which target Japanese beetles well are Merit Granules- Turf Insecticide or Evergreen Pyrethrum Dust 1%.

  1. Cocktail for the Japanese beetles

Place an open can of fruit cocktail in the open the sun for a week. It will cause it to ferment. Once the cocktail has been fermented, use wood blocks or bricks and cinder blocks to make a strong base to place a bucket filled with fermented cocktail and water. Place the pail approximately ten feet away from the plants. Once the Japanese beetles sniff the scent of fruits, they will ignore the plants and get more attracted towards the cocktail. They will crawl into it but will be unable to climb their way out and subsequently get drowned.

  1. Choose your plants wisely

Japanese Beetles are attracted to almost every green plant. However, there are a few plants which they consider less desirable. Such plants should be cultivated in the gardens. Few examples are as follows:  Magnolias, Tulip tree, White Ash, Dogwoods, Lilacs, Red Oaks, and white Oaks and Green Ash etc. these plants that Japanese beetles will usually avoid feasting on.

  1. Homemade oil spray

Create a mixture of oil spray by adding one teaspoon of dish washing detergent with one cup of vegetable oil or even castor oil. Diluted the mixture with some water and 1 cup of alcohol. Pour it in a spray bottle and mix well. Spraying this insecticide on the Japanese Beetles will eradicate the insects. Use the spray after ten days of interval.


Japanese Beetles do cause a lot of damage to the greenery and the Landscape in general. Therefore, it is important to take all sorts of measures to prevent, control and eradicate these insects.
