I prefer the soapbath.

Here is a clipping I saved from another thread, maybe you read it:

from andy - on June 4

I"'ve had excellent results with imidacloprid, applied as a soil
drench once a year. I used to have constant mealie problems but since I
started this regimen I haven't had a single issue. Since it's a
long-lasting systemic I don't worry about pests coming in from new
plants either because as soon as they try chewing on the protected
plants, they're toast.

I know not everyone is keen on neo-nicotinoids but for this number of
plants I don't see it as a problem. I always apply after flowering to
minimize the possible impact on bees and other pollinators."

Good advice from Laurent in same thread, about 'bath' he uses to prevent fungus, but may be good guide for other problems? (using appropriate product):

"In order to avoid fungal disease I always water my cuttings with water +
special systemic fungicide. And when I receive a cutting I bath it
between 2 and 6 hours (until it's hydrated again) in the same solution. I
also do it before shipping a cutting."

..." not just preventive, it's curative too (if the plants are correctly cultivated).
I also do it every time I transplant a succulent from one pot to another (stressed plants are easy targets for fungi)."...

Hope some of it will help.

@ Hablu... Speaking as a humanoid, i like my soap baths hot. ;-)

Hot Water Dips with 120F water till root ball reaches 115F.

On the way up the slope ( a good note) if I where a pest I wouldn't last very long in those temps . On the way down the slope, if I where the plant I'd be eradicated before the pest.

My plants have lived at 115 during some times in the summer and my tap water has been close to that at times, . They were talking palms . I was just curious about this. Un. of Hawaii is a good ag school.

if you google hot water for mealiebugs there is a lot about this-the general agreement is it's good for what ails you.
