I treated my trees approximately 10 days ago with Bifen to get rid of leaf miners. Yesterday I noticed that my trees are all turning brown and the leafs are falling. When I looked closer they are all covered with small black bugs. Do I need to treat them with something different or treat them again with Bifen? Will the leaves come back again this year?
We recommend getting the little black bug identified so that we can properly advise you on treatment options. You can contact your local cooperative extension office for insect identifications.
