Japanese Beetle Rose Damage – How To Get Rid Of Japanese Beetles On Roses
JAPANESE BEETLES ROSE DAMAGE ON ROSES
The first thing you need to do is to make sure your rose bushes are not infested with any type of insects such as ants or termites. If they are, then it will take them a long time before they recover from the damage caused by these pests.
If you have Japanese beetles on your roses, then there is nothing you can do except to wait until they die off naturally. You may want to try spraying some insecticide around the area where the beetles were found, but if that doesn’t work, then you might consider using a natural method of killing them.
What Is Natural Method For Killing JAPANESE BEETLES?
There are many different ways to kill Japanese beetles. Some of them include:
1) Insecticidal Soap Spray – Use a small amount of insecticidal soap on the affected areas.
Let it sit for at least 15 minutes and then wash off thoroughly with water. Do not use too much soap because excessive amounts can cause irritation to the skin.
2) Diatomaceous Earth – Dust the affected area with this insecticide.
It will dehydrate and kill the majority of the JAPANESE BEETLES in just a few hours. It is most effective when it is dry.
3) Neem Oil – This is probably one of the safest ways to get rid of beetles on your roses.
It is a great treatment because it not only kills them, but also prevents further infestation for up to four weeks.
4) Pyrethrin – This is a man-made version of a substance that is found in chrysanthemums.
It is a great way to get rid of beetles, but it does not last very long. Since it is a man-made substance, it can also be very dangerous if not used properly.
5) Horticultural Oil – This oil smothers the JAPANESE BEETLES and kills them.
It also has the advantage of breaking the lifecycle of the insect. It must be applied thoroughly to all roses and it must be reapplied after a rain.
6) Drown Them – This is a very simple, yet effective way to get rid of the beetles.
Get a bucket of soapy water and pick off the beetles from the bushes. Then put them in the bucket and leave them there. The beetles will float because soap is not good for them.
What Is The Natural Spray For JAPANESE BEETLES?
You can also make your own spray to get rid of the beetles. It is not as strong as the horticultural oil, but it can be very effective if you use it properly. Here is a recipe:
1 gallon of water
11/2 cups of apple-cider vinegar
1/2 cup of cooking oil
20 drops of peppermint oil
20 drops of rosemary oil
First, mix all the ingredients in a spray bottle. Shake it well before each use. Spray the affected areas thoroughly and repeat every three days until all the Japanese Beetles are gone.
What Should I Do If The Natural Spray Does Not Work?
If the natural spray does not work after a few applications, it is probably because your roses are under attack by other insects as well. In this case, you’ll need to use an insecticide to get rid of the other insects and then use the natural spray to keep the beetles away.
Does The JAPANESE BEETLES Natural Spray Have Any Side Effects?
The only side effect of this spray is that it may cause dermatitis in rare cases. It is best to do a small patch test before using the spray on your whole rose bush.
What Should I Do If I Still Find Beetles On My Rose Bush?
If you have followed all the steps and you are still seeing Japanese Beetles on your rose bush, you should contact your local nursery or gardener about professional help.
How Much Does This Organic Japanese Beetle Spray Cost?
These ingredients don’t cost very much at all. You probably already have most of them in your kitchen. You can also find the other ingredients at just about any major grocery store or department store.
Here is the cost of each ingredient:
1 Gallon of Water – Free (You Probably Have This In Your Home)
3 Tablespoons Of Apple Cider Vinegar – $1.00 (Any Major Grocery Store)
1/2 Cup Of Canola Oil – $1.00 (Any Major Grocery Store)
20 Drops of Peppermint Oil – $4.00 (Any Major Grocery Store)
Makes The Whole Thing About $5.00
This is a very small price to pay for getting rid of these beetles. This is especially true if you take into account how much you could spend in professional help.

Here’s to having your rose bushes beetle-free!
Now I’m going to give you some advice that you probably aren’t going to like, but I think you need to hear.
You need to take a lesson out of the Japanese Beetles’ book if you are going to get rid of them.
That means if you see them in the area then you need to get rid of whatever they are eating. In this case, it’s your roses. I hate to say it, but you may need to consider getting rid of them. It’ll be a sad day if you have to do it, but if the beetles are persistent then they are going to continue to come back no matter what you do.
The other thing you need to do is call your local nursery or garden center. They need to know there is a Japanese Beetle issue in your area so they can prepare for an onslaught from other people in your area. More people are going to start bringing their rose bushes in if they are having issues and the garden center isn’t going to be prepared for that.
The last thing you can do is sit back and wait to see what happens. I don’t know if spraying the natural spray will change anything or not, but it’s definitely better than just letting the beetles take over. If everything else fails at least you’ll be able to say you tried everything in your power to save your roses.
Good luck whatever you choose!
