Scale is a common problem on houseplants, it's not unique to citrus.  When 
I used to get scale on my houseplants they always improved when I put them 
outdoors in the summer, so I presume something eats scale, too.

I had good luck removing scale from my myers lemon by:

1) removing what I could by hand.
2) washing the tree with a hose.
3) spraying with a light hortacultural oil the next day.
4) getting rid of my most scale-prone houseplants.

My myers lemon is a houseplant in the winter, and goes into the ground in 
the summer.  I did this several summers ago and haven't had scale on it 
since.

scale. I did some reading about them since I had never heard of them 
before. I picked them off by and and cleaned each leaf and branch. The 
trees look much better. What I can't understand is where these critters 
came from. I have a Meyers Lemon and a Lime Leaf, both growing in pots. 
Both have never been outdoors. Both were started from seed by me. I am 
almost 1000 miles from any citrus orchard. How did I get scale? Since I 
started with seed, that is the only source I can think of, unless they 
drifted in by air through an open window.
