Don’t wait till the last minute to take care of those pesky Japanese beetles, try a proactive approach with systemic soil treatments. This approach is only available for non-flowering trees that do not host pollinators (ex: Elm, Birch and Japanese Maple trees), we do not recommend this treatment for lindens, fruit- bearing trees or shrubs.
So what exactly are systemic soil treatments you ask? This environmentally friendly alternative locks and loads your tree’s leaves now with insecticide so they’re ready to kill the beetles as they emerge from the ground and feed. Only sucking and chewing insects such as Japanese beetles would be affected by this insecticide. Systematic soil treatments are injected by a probe around the tree’s root system and kept in a localized area.
If you are looking for an effective way to treat your lawn from Japanese beetles, consider a grub treatment. While this is good for your area it will do very little in preventing beetles from flying in someone else’s yard.
