Arborvitaes Have Turned Brown Where Sprayed For Mosquitos
Question From: H. Horton - Lewis Center, Ohio, United States
Q: There seemed to be a lot of mosquitos around my arborvitae's so I sprayed areas of the tress with Cutter insect repellent. Now the areas of the trees that I sprayed are brown. Are the leaves dead or just discolored?
I can't tell from here. Next time spray the tree with a product called Mosquito Barrier. Use it according to package directions. Best And Happy Yardening, Nancy
