Does anyone have this problem? I have tried everything I know of to get rid of the little buggers but they infested almost all my plants in my yard and they suck the plant dry until it dies. When you brush by a plant that is infested, a flurry of tiny white bugs (millions) float off the plant, only to return later. I have tried the yellow stickies, oil and water, insecticidal soap, and now that we are coming into hot weather again (its AZ), I know these bugs will all be back. They LOVE the potato bush with the purple flowers, the Lantana, the bougs, petunias, etc etc. Can anyone help???

Never had a problem with them down on the coast of NC, but have been battling every year I've been here in the Triangle.

Whiteflies are horrible, and the only luck -- albeit temporary -- that I have had, has been to use systemic pesticides. Of course, by the time the stuff is in the plants (and if the systemic stuff doesn't damage the poor plant, too) the whiteflies have just about killed it. I think it's a Bayer product, but I'll double-check.

The fellow at the nursery where I buy my plants says they are difficult to treat, and that you have to treat the soil, too. I have noticed good air circulation helps, too, as they don't like to be disturbed? I may be investing in some wind-tunnel, turbo-blasting fans. I ended-up throwing out whole pots of petunias, and replacing all of the soil in my window boxes. Darned if they aren't after pansies now.

**Crossing fingers** Fortunately, I haven't seen them in some of the plants you mention. Lantana? I thought nothing went after it.

Good luck. I'll check the name of the product for you when I am in the gardening shed, if I can remember which product I used with some measure of success. I have tried so many to combat whiteflies, myself.

Spinosad might be helpful. I swear by it for flea beetles and Colorado potato beetles. There's a study that shows it effective on whiteflies. You have to be careful to not use it when flowers are open as it kills pollinators. As long as the liquid is dry before the bees are out for the day it's fine.

Actually you've done about all you can do to rid yourself of those pesky whiteflies. Soaps, stickies and insecticides are primarily it. They proliferate like crazy in the desert areas. If you miss one or two they proliferate, if your neighbors have them and they don't do anything about them they proliferate and find your yard. The farmers are having a time with them also. It's a losing battle til winter comes. The only suggestion is to plant something that doesn't attract whiteflies.

I've heard Lantana attracts whiteflies in AZ. Is this what you have in your yard?

Try using soap and oil. It works in our garden. Now if we could only get into our neighbors infested yard to spay.

I've been gardening here in the Caribbean for a couple of decades and over the years have tried pretty much everything. The only thing that consistently works for me is Ortho's Malathion Plus. For a heavy infestation cut back all the badly rotted stems and spray every day for a week, then spray monthly for maintenance. It's pretty stinky stuff but follow the directions and it works like a charm. Cheers!

Default Getting rid of white flies

1tbsp vinegar, 1/2-1 tbsp dishwashing liquid, liter (quart) of water, spray bottle. Hibiscus was covered in them (inside atrium) Sprayed them with this and pretty much drowned/killed most of them last night. Saw this on the web. My mix is a little stronger (4x) what the web recipe suggested. None around today. They say to keep applying everyday until the last fly dies. You could probably get a hose attachment that you could for outside in your yard.
