DaisyI said:Mealybugs plus nests. Lucky you! You can spray your plant with alcohol to kill them (then rinse them off). Watch for more.
Hi Daisyl, thank you for your input. I did a bit more research and found that mealybugs leave a sticky honeydew on the leaves, ...
whilst looking with more light I found some very fine webs and a tiny spider,
So I'm so confused, as online pics of mealybug searches aren't bringing any resemblance to what I'm finding
No they don't
So you have mealybugs and a tiny spider
Look up "Mealybug nest." I would treat them soon. Mealybugs have a very short life cycle.
The treatment for most bug infestations is the same: Insecticidal Soap or alcohol. So, even if you aren't convinced its mealybugs, are you willing to wait until you are satisfied with the answer before you do something?
WillC said:I don't think you have a pest problem. The leaf deformities in your original phots were not caused by any pests. If you have found only a single critter, that is not a cause for concern. A live mealybug infestation would be more visible to you and there would definitely be sticky honeydew found on some leaf surfaces.
The webbing in the photo you posted is normal house spider webbing and not spider mite webs.
Your Schefflera arboricola looks very healthy.
FYI - The Wilko product you are using is moderately toxic and carries a Warning label. It is broad-spectrum and includes a fungicide. There are safer, non-toxic treatments for indoor pests that are very effective and much less toxic. But in the absence of a specifically identified pest problem, it is best not to use anything.
No need to be rude, and never assume, where did I say I haven't treated it yet?
WillC said:What is visible in the photos is hard to identify positively. If you are not seeing much of it, then I doubt it is a problem. I would expect a significant pest problem to be more widespread and more easily identifiable.
To be on the safe side, spray and wipe all leaf and stem surfaces with a mixture of 5 parts water, 1 part alcohol, and a squirt of liquid soap.
