Q.Lace bugs in rhododendrons

Zone Renton, Wa. 98058 | gavlewis added on March 22, 2018 | Answered

I have a bad infestation of lace bugs. I can use a backpack sprayer but it is very difficult to get the undersides of the leaves. Also the amount of spraying is formidable!
Now there are backpack type sprayers that combine the leaf blower function with an insectitide such as neem to produce a fine mist. Some people use this type sprayer to control mosquitoes but I have not found anything regarding lace bug control. I would like to know if this is an effective treatment Specifically, with the air blast does the mist coat the leaves top and bottom sufficiently to kill the larve. If it works it would be much easier to apply. I hope you can help me!!! George Lewis

It is worth a try! Neem oil is quite viscous, so make sure that what you choose can handle thick liquids. This would be a good way to, virtually, coat the plants.
