Sounds like Aphids....
They pinch off very easily...
*outside, I take a hose to them, inside,
I might just wash the leaves, etc.. in sink
after pinching them all..*
(by pinching them, I mean squeezing them)
And then I'd look at the care of the
plant indoors,
what's causing the aphids to be attracked to the
plant...
When a
plant gets something like aphids, it means
it's probably getting fertilized too much, or spindly growth
(sun light's not right)... *that's the part that they like
eating is the fresh tender new green growth*...
or too much heat on them...
