Butterfly Bush

Asked June 4, 2020, 12:13 PM EDT

I have a butterfly bush that is being eaten by what looks like a mite. I want to spray a 3 in 1 spray that I bought from Valley View Farms. I have used this spray on my azaleas and roses but this will be the first time on the butterfly bush. The active ingrefients are: Tau-fluvalinate - 0.61% Tebuconazole - 0.65% Other Ingredients - 98.74%

We would not recommend spraying your butterfly bush with that pesticide.

Butterfly bushes are tough plants with few problems.
As with any problem, correctly identifying the problem is the first step in learning what do do.
Could you please describe the issue you are seeing that makes you think it's mites, and even better, take a few photos of what you are seeing? Up to three at a time can be attached directly to this reply by using the Choose File tab below.
We'll be happy to take a look and advise.

It's important to know that the pesticide you are using is a pyrethroid that kills all kinds of insects, many of which are beneficial and naturally take care of landscape pests for us. It also contains a fungicide, which might be of use for your rose but not likely for your azalea or butterfly bush. The less pesticides we put into the environment, the better for us and the health of your landscape.

Christine,
Thanks for the quick response.
Attached are two pictures one is of a leaf and the second is of the little black bugs that are on the underneath of one of the leafs.
This plant means a lot to our family.
Thanks and stay safe,

Good news for you.
The first photo shows what is just old incidental damage from a caterpillar or beetle that is long gone. The plant will continue to push out new leaves.
The second photo shows a red bug on the left edge that is not hurting anything, and it looks like, from the curling and the webbing that there may be a leaf rolling caterpillar under the edge. If you open it you can investigate.
The black dots you are seeing look like caterpillar poop. The caterpillars and bugs act as bird food.
If only a small percentage of a mature plant has some damage and the rest of the leaves look well, not to worry. It is a natural part of a healthy ecosystem to support much biodiversity. 'Perfect'-looking plants are important to people who sell them, but as homeowners/gardeners, an acceptable level of damage is key to an overall healthy landscape.
Feel free to contact us again any time with your questions.

Christine,
Thanks for your response and I will keep an eye on it. At this time there are 4 leaves that are damaged and the rest of the plant is healthy.

A worrisome level of damage where you would consider taking action would be at about 30% of the plant.
We use a research-based holistic approach to landscape issues called IPM: Integrated Pest Managment. You can learn more about that here:
