scale problem on plant


Question
Hi, Will,

Thank you for the answer before.
I tried to spray the fluid I can buy in Canadian Tire for treating scale problem.
Also I tried to scrub the bug out by using hand with glaves, mop etc.  There is still some that can be seen.  
It has been two weeks.  How long can it be cured?
what should be scale be looking like when the problem is solved.  After the spraying, I don't see any difference actually.  The most effective way I saw so far, is my using glaves, mops to scrub them away.  I also took some of the leaves off if there were too many of scales.

I tried using rubbing alchahol, with soap, wanter as well.  Not much effect.

Any advice?
Thanks for your help!

Answer
Hi Li,

Please read my first reply carefully. The key to success with scale is thoroughness of coverage. You must get complete coverage of ALL leaf and stem surfaces. Alcohol ans soap is effective but only if you get complete coverage.

After spraying, wiping with a soft cloth should remove the remains of the dead scale and none should be visible after that. If you see some, that is probably because you missed them when you wiped. If you are thorough, the cure will be immediately on contact.

Use mild soap and water to remove any stickines on floors or furnishings under the plant. After the scale insects have been removed, there should be no further stickiness.

I have no idea what "fluid from Canadian tire" is, so I cannot say whether it is effective in treating scale.
