Any idea what type of pest this is growing on plant

Wife just noticed some tiny little pests growing on a rose of sharon in her flower bed. These tiny little things are all over it. Any idea what they are and what to treat the plant with to kill them?

Thanks,
Blake

I think it looks like aphids as well. They can be washed off with a hose, insecticidal soap, neem, malathion, any systemic or just about anything else will control them.

We treat all our susceptible plants with imidicloprid. It will last all season.

Blake,
The shrub is the Althea or Rose of Sharon.
This species is really susceptible of aphid damage when the temps get warmer. I will tell you that one spraying will not eliminate the whole brood.

Lady Bugs are Great...........In an enclosed Green house.

The problem with releasing Lady Bugs is they fly away and only a few remain to be of any Benefit. However Green/shade houses that are Screen Tight will hold them in where they can be very beneficial.


Irritech I agree with the Imidicloprid, how ever watch for Spider Mites. Imidicloprid is actually a Grow regulator of Mites. Only it increases Birth of Mites.

Ric,
Funny you should mention this. As I have heard of aphid control with the use of natural predator insects. What I find interesting is the companies that make great money selling this practice to customers that are willing to pay big dollars for natural control. In all fairness, the lady beetle will just fly away, maybe eating a few as they seek other suitable dwellings.
Years ago, a long term customer paid a organic natural grower 500.00 dollars for a dozen boxes of beetles released on their weeping willow. The release didn't work. Maybe if you built an enclosure around the tree and left it there for a week or so, the numbers of aphids would disappear.
I have seen natural processes where the number of aphids is lower and a few lady beetles did control the populations. However, in a large infestation as such in the picture, it will take more beetles than good to do the job.

Blake711,
If I remember well, blasting the plant with coarse water, the aphids will be removed. Take note not to use a compressed brass nozzle hose attachment. You don't want to blow the leaves off the plant, all you want to do is spray off the aphids. Most times the eggs will come off also. Use dawn in a hose end sprayer to wash off the sticky residues.

To late for imidocloprid now, you'll need curative and i could think of a few better chemicals for that. funny people mention lady beetles, my son did his science fair project on this subject. We releases 1000 lady beetle on an infested viburnum hedgerow and documented over the course of a week how many actually stuck around to eat. I was surprised just how many stayed put, I guess if there is a food source and shelter why would they leave? and they didn't. They also couldn't even come close to keep up with the aphids ..........so some Acephate and safari (mealy bugs there too) took care of them and the lady beetles....He won first place for his school and went to district fair too
