Bad Bad Bad!

The affected shrubs are defoliating and appear to be dying out in places. The infestation appears to have started within the shrubs which have been kept sheared for a number of years, hiding the scales untill they began appearing on the foliage. This wasn't noticed by the owner until the foliage began to die.

As I understand it, this is another of the very hard to eradicate scales.

Beware and be aware before it gets out of hand as it did on the shrubs pictured.

I have had this problem, as has my neighbor down the street with the same kind of euonymus hedge as the pictures. It seems to be worse on the more sheared hedge(which mine is not) It seems to go for the tender growth. I have reduced the scale a lot by raking out the debris under the hedges to reduce the overwintering whatevers. I also don't shear routinely, just 2-3 clippings a year and trying to thin out the clumps which grow after clipping.

my garden is in still in planning but i work for mobjack nurseries in mobjack, virginia. i,m not sure if this is the same scale or not,but we had a horrible problem on our akubas. it was finally taken care of by heavy spraying of synergy(oil based insecticide that suffocates the little suckers) and constant attention.

I'm currently trying to rid my front yard of this mess. If you've had success with your treatment I would greatly appreciate any advice.

The issue: scale on euonymous in late summer. It has been very hot in St. Louis this summer (Big Surprise). I discovered the scale problem on our north facing euonymouses only this weekend and it is far advanced on the rear of of two of four adjacent 5 ft. bushes near the foundation of the house. I gather that there is next to nothing I can do at this point, except to go to dormant oil later, assuming that the plants survive. Thinking that what I was seeing were insects, I sprayed this weekend with an insecticide, but now find out that doing so wasn't my best idea since I most likely zapped the scales' only natural predators. Is there anything positive that I can do now? richard1039

This scale went after a shrub in my back yard in Summer 2008 (Austin Texas) - it covered the trunk and branches completely! I sprayed it with a commercial bug killer for shrubs and flowers, had to dose it several times but realized I had to simply cut it down to a 2' nub, and then scrub the dead scale off of it after that. (Scrubbing the scale off of it gave me a good reference to see if it was coming back in the future!) This was a tough fight! The shrub has come back beautifully, but I am now fighting (2009) the scale on all of my 4 O'clocks! Over and over I spray, both the commercial sprays and my own soap/water spray. I realize now that I'm going to have to pull the affected ones up and out, I'll clean out around them, and I will continue to spray a soapy/oily treatment on them often. I am treating the soil as well. This website and your readers' comments have helped me to know that I have a fight on my hands that won't be easy. Thanks all!

If this is the same scale. I had it on my Camillia bush they live under the leaves and you almost have to scrub them off. I noticed that when I tried to take soap and water to clean each leaf there were "guardians" that would bite me. I had no ill effects from the bites and actually a mosquito is worst. Everyday I would check to see if they came back. Finally, I decided to use an insecticide to kill them. It still took several treatments. One suggestion though no matter what the bug. Spray the ground around the infested plant. Some of them may have fallen off and reinfected the plant. Good luck!
