    What would you guys recommend spraying on my trees and rose bushes to keep the japanese beetles from doing too much damage?

    I'm a homeowner, so something stocked at Home Depot or Lowes would be easiest.

    The beetles have been terrible the last two seasons, total hell on my plum tree.

    There is no repellent for Japanese Beetle adults. The insecticides Sevin and Bonide Eight give short term control of beetles that are feeding on the tree, usually a few days at best.

    Suspend SC ,Crosscheck or any bifenthrin product. apply ever two to three weeks depending on insect pressure. however, you will find no such product at Home Depot, so I would recommend contacting a lawn care professional .

    Ortho's Malathion will help control them, but be prepared to apply it weekly, and then it's only control.... not eradication.

    Season Long Tree and Shrub Insect control by Bayer. This is imidacloprid, a systemic insecticide applied to the roots of the trees and shrubs. If you have lots of trees and shrubs to treat, it might be worth getting a professional to apply Merit. On spraying trees and shrubs: I have yet to meet a DIYer with good spray equipment unless he is also a farmer with a 50 or 100 gallon power sprayer. I love the acid-tongued answer given by my friend when people ask, "what do I spray my trees with?" "A power sprayer..........................." What follows that is usually imprintable.

    Call a professional and use merit as a preventative and crosscheck as contact.

    you to late for a soil drench application of merit, or the Bayer product. takes up to two months to translocate from the root zone to the leaves.
