Let me know if this photo is too blurry and I'll try to get a better close-up. From this photo it looks more like a white smear rather than the actual thin strands as they appear on the leaf itself.
White fly, spray with soapy water every 10 days, it will get rid of then.
Thank you. I started with soapy water yesterday but I worried that it might not be be sufficient so I took marco buijsman's advice and just now gave it a spray of Pyrsol.
Several years ago someone here recommended white fly straps, which were sticky yellow things that attracted white flies. They worked and I haven't had a problem since. Available on Amazon.

I have used the Yellow Fly Sticky Pads for trapping Fungus Gnats with success.
