Question:

I am new to growing succulents and I really appreciate a good source to go to for help and advice. But, my question is about the alcohol, can that be used on other plants without damage? Does it matter if it’s 70% or 91% alcohol?

Also, will it work on other types of scale like soft brown, sooty black, powdery white, etc? I realize this is wandering off the path of succulents, but, I’ve been gardening for 40 years and most any kind of scale are born in HELL. Looking for any kind of advice I can get. Thanks for your time.

Answer:

Alcohol is a really great solution to mealybugs, scale, and other pests on succulents. You can also use it on your other houseplants, as well, but I would be sure to test it first, as it could damage some.

I’d recommend a 70% solution – it evaporates slower than the 91% solution, but because of this it can break down the waxy protective layer of pests, while evaporating quickly enough not to harm your plant. This should work on all types of scale.

You may have to reapply the solution every 2 or 3 days until the scale has been eradicated.  In my course, I cover scale in detail.
