The Northfield area is facing increased problems from insect pests on landscape plants. It may be a good time to start thinking about how you will choose to manage greater pressures from these destructive insects, so my friend from Termite Survey gave me a couple of tips and tricks that I’ll share below.
Boring insects of various kinds can destroy Birch, Oak, Linden and Ash trees and Viburnum shrubs. There is a chemical treatment that is effective at controlling and/or preventing borers. The active ingredient is Imidacloprid and is available in many commonly available pest control products. Applied to the soil next to the stem of a tree or shrub, Imidacloprid is absorbed by the roots, and prevents dozens of insect pests in addition to borers from attacking the plant. Treatment is simple, safe and effective.
Japanese Beetles are showing up in greater numbers. Soon they will be widespread in the Northfield area. We are all going to have to learn more about controlling this VERY destructive insect. You may be interested to know that Imidacloprid gives pretty good control of the Japanese Beetle and about 35 other insects, which helps property owners avoid having to spray foliar applications of conventional insecticides.
