Masdie with mite issues

[Paul]

Well I have a masdie whose leaves were starting to look 'funky' here and there. Upon wiping the leaves with an alcohol dampened cottonball, I found little red dots on the cotton -- hence my mite diagnosis.

So now I'm wondering how to treat it. Masdies seem so sensitive to fertilizers and such that I'm leary about using a systemic like Bayer's 3 in 1 (which is my first impulse). Would this be too strong for the masdie?

I had also toyed with the idea of bagging up the masdie for a few days with a piece of flea collar in the bag. Any idea if this would work and if it would be detrimental to the plant?
