Just arrived .....32oz Organic Insect Killing soap particularly for Mealy Bugs and Coleus loving insects. My question is this....do I WAIT until first sign of insects or do I use this preemptively ? I understand it breaks down the membrane of the insect..so Im guessing the earlier.

It is a last resort for me but I definitely use it on the mealybugs when they get bad , I urge caution though as not to spray any beneficial insects

like this lady bug larva

Yes I read up a bit on it.... Lady bugs....now who could kill a Ladybug????!!! Not Me!!! Thanks

Yeah I stopped using systemic granulated stuff too.. does too much damage.. use soap or alcohol when it gets bad
