Take a look at the following website for some help. There are many ways to deal with it.

Subject: pit scale
Can anyone give me any information on Pittosporum pit scale ( asterolecanium
arabidis--often referred to simply as 'the pest' in APS journals) I have
done an Internet search, but have been unable to find any specific
information.
Several of my penstemons are exhibiting what could be symptoms of this
pest--twisting stems with occasional swollen nodules and evidence of some
pitting. My questions are this:
How serious should I treat this infestation? Let us say we have a relative
scale of responses with extremes on either end:
Most radical approach--do everything possible to eliminate infested plants,
put a huge plastic tent over the House, release extremely toxic pesticides
that will kill everything for 1 mi. radius.
Most lax approach--watch the impending doom of penstemons with an air of
tolerance and think to oneself , "My, how complicated the universe is. "
Clearly, neither approach is appropriate. What is a reasonable response? Is
this scale likely to destroy everything in my garden ? (Based on what
limited information I was able to find, I discovered that all of my favorite
plants are favored food sources of 'the pest'. ) Or will it remain
relatively in check, causing localized damage at some times of the year but
otherwise not interfering with the overall harmony of the garden? How
common is this problem in California?
Any information you could send me would be much appreciated.
I am a recent subscriber to this list, and apologize if this is an old and
weary subject.
