How To Keep Japanese Beetles Off Roses

The Japanese beetle is a small, metallic green beetle that is native to Japan, China and Korea. The beetles are considered an invasive species in the United States and are very destructive to plants and trees of all kinds. In the summertime, they feed on the leaves of roses, raspberries and other plants.

How To Keep Japanese Beetles Off Roses

Here is the complete process explained in detail on how to keep japanese beetles off roses:

1. Step 1

1. Use a soap spray to prevent them from laying eggs on your roses. Spray the undersides of the leaves with a soap solution (1 tablespoon of liquid dishwashing detergent per quart of water) every two weeks from early June through mid-August. This will help keep the Japanese beetle population low.

2. Step 2

2. Pick off beetles by hand, or knock them into soapy water with a spray bottle.

3. Step 3

3. Remove any fallen leaves that may serve as hiding places for eggs, larvae and pupae.

4. Step 4

4. Treat your roses with an insecticide labeled for use on roses if you need more control than you can get from hand picking and spraying with soapy water (see below). Insecticides containing carbaryl, malathion or permethrin are most effective against adult beetles and their grubs, which are found in the soil around the roots of your rose bushes in summer and fall. Be sure to follow all label directions carefully when using these products; they should never be sprayed on plants when temperatures exceed 90 degrees F., because they can burn foliage, flowers and fruit.

5. Step 5

5. Remove any mulch or other debris under your rose bushes to discourage egg-laying adults from congregating there during spring and summer months when they emerge from the soil after winter dormancy has ended (mulch is fine to use in fall).

6. Step 6

6. Keep grass mowed short near rose bushes, since Japanese beetles often hide in tall grasses during the day before emerging at night to feed on roses and other plants in your garden or landscape..

How do you keep Japanese beetles away?

This is a question that I get asked frequently. Japanese beetles are an invasive species and they love to eat my plants. My favorite way to keep them away is to plant Nasturtiums in pots throughout the garden. The flowers of the Nasturtium attract beneficial insects and repel Japanese beetles. It’s a win-win situation!

I also like to make a spray using water, apple cider vinegar, peppermint oil and garlic infused olive oil. Spray it on the plants that you want to protect from Japanese beetles (don’t spray your herb garden though!)
Japanese Beetle Trap Recipe for Organic Gardeners


1 Small Jar with Lid (I used an empty peanut butter jar)
Nail or Screw in the center of the lid (make sure it doesn’t come through both sides)

2 tablespoons Apple Cider Vinegar
Pour vinegar into jar until about 1/4″ from top. Add 2 drops of peppermint essential oil and 2 cloves of crushed garlic. Place lid on jar and screw nail or screw through lid into side of jar so that it creates a trap door when closed. Hang in garden where you’ve seen Japanese Beetles feeding on your plants. When full, dispose in trash outside your home. You can also use this trap indoors if you have lots of them flying around inside your house during the summer months!

Can Japanese beetles kill a rose bush?

Japanese beetles can kill rose bushes. The beetles chew on the leaves of the plants and can cause them to die. They are also known for laying their eggs on the leaves, which causes maggots to hatch and eat the leaves of the plants. To keep this from happening, it is recommended that you plant some marigolds around your rose bushes. Marigolds are a natural deterrent for Japanese beetles.

How do I get rid of Japanese beetles?

The best way to get rid of Japanese beetles is by using traps or pesticides. You can try setting out yellow sticky traps around your property in order to catch them before they fly onto your plants and start chewing on them. You can also use pesticides, but try not to spray too much because it could harm other insects that are beneficial to your garden as well as yourself and your family members if you breathe in too much pesticide while spraying it around your home’s perimeter.

How do you get rid of Japanese beetles without harming plants?

Japanese beetles are pests that feed on the leaves of plants, flowers and fruits. They are one of the most destructive pests in the United States, especially in areas where they can multiply rapidly. Japanese beetle traps are a great way to get rid of these insects without harming your plants.

How do Japanese beetle traps work?

Japanese beetles traps attract adult beetles with pheromone lures and food-based lures to a sticky surface where they will become trapped. Traps are most effective when placed near susceptible plants like roses or fruit trees, but they can be used anywhere you have noticed infestations.

The traps use pheromone lures to attract male and female Japanese beetles, which will then become stuck on the trap’s surface. These traps work best in areas where there is a lot of foliage for them to feed on. When placing the trap, it is important that it is placed away from other plants so as not to harm them with any chemicals or oil left behind after trapping.

The best place for this type of trap is around roses or other flowering plants that you want to protect from damage by these insects. Since this type of trap uses pheromones to lure in the insects, it is important that it be placed as close as possible to susceptible plants like roses for maximum effectiveness.
