Mealy bug question

I have this Bougainvillea, in a small hanging pot with just one 7" inch branch. Its indoors here in the northeast, and weeks ago I discovered this white patch under the leaves. I sprayed it with alcohol and pull off those white patchs. Doesn't take long to look at and treat. Since then its bloomed again on that one branch. A few weeks gone by and each day of those weeks I checked it out and saw nothing resembling them..so i thought finally I got rid of the problem, but to my dismay i saw one yesterday on one of the leaves. Pulled it off and sprayed again. I look very closely to each node and like I said its only aabout 7 inches long. I want to keep this plant. Is there no way for me to get rid of the mealy bug permanently? I'm concerned as it grows more branches.

What you are doing will work with periodic inspections. Mealy bug is not too difficult to eradicate. Personally, I would not have a problem due to the lady bugs that are finding their way into my home (lady bugs dine on mealy bugs). The life cycle of a mealy bug is about one month. There are two types: One has a long tail and bears live young; the other has a short tail and lays eggs. Look especially where the stem meets the leaf. The young have a yellow color, turning to fuzzy white as they mature. Take your plant to the shower twice a month and give it a forceful warm shower. As a last resort you can use an insecticide (made for indoor use)--three treatments, spaced 14 days apart should work. Ants are notorious for spreading mealy bugs, as they "farm" them for the sweet honeydew extract.

Repeated sprayings with water is good. As a matter of fact that is what I do to my veggies in the summer and I never have to use chemicals on them. In the past what I do for mealy bug indoors is examine the plant very carefully and remove the all the little buggers with a Q-tip dipped in rubbing alcohol. This has worked for me. I generally get rid of them the first time around.

You will get suggestions for all sorts of home remedies. For mealy bug, you will need a systemic insecticide, either Orthenex or Di-Syston granules. Neither of them is disastrously dangerous if you use them correctly. Check the label carefully to make sure it is OK for Bougainevillea or its close relatives (four-o-clock family). Spray with Orthenex in the garage or an unused room, & leave the plant there for a couple of hours.

Repeat application of Orthene, read and follow all label directions.
