My Hiscus plants grow well for 15-18 months here in zone 10a. Then I start to see mealy bugs on the leaves, mostly on the undersides of the leaves. I have used things like Bayers 3in1 but the bugs get the upper hand.
What appears to be small white scale starts to. Take over the twigs and branches overwhelming the entire plant fairly quickly. What can I do?

Get rid of an many bugs as possible. I like to use a spray mix of 1 part rubbing alcohol to 3 parts water. This is a contact killer so wet the plant thoroughly and wash the bugs off. Then use a systemic such as Bonide or Neem. I like systemics because they only kill the sucky bugs, not good bugs. Neem is safe to use on food crops, but Bonide is not.

Systemics don't work instantly so watch for re-infestations. After a couple weeks the systemic should be working.

You have to do what Daisy has said, and keep at it. I have lost a huge number of hibiscus to the mealy bugs and scale. They need to be checked frequently. If you find them when it's a small problem, you can fix it and keep your plant. Sometimes they get so infested it's just better to start over with new plants. We are dry in AZ and NM, but in florida the problem is probably much worse because of the humidity.

Thanks very much.
It sounds like I have to be more aggressive early on in my treatment.
I have a 1 1/2 gallon pump spraying so I really need to hit the little beasties hard with several follow ups. Misting here and there early on is allowing these pests to multiply at an alarming rate.
It is good advice and I'll give it a shot for sure. Thank You!
