I live in Seattle. This tree is in a large container, a house plant 8 months
a year. I put it outside during the summer and so far haven't had a problem
with scale or any other pests, even the spider mites seem to be gone when
it's outside. I always give it a good soapy shower and dig D.E. into the top
soil of the container when I bring it back inside in early fall.

There's a nursery near by that sells lady bugs, I'll give that a try. Even
if it doesn't work lady bugs are pretty darned kewl. Maybe that's why I
don't have a problem when it lives on my balcony in the summer. I always
have loads of lady bugs out there in the warmer weather.
