We understand that sometimes you have to control the Spotted Lantern Fly preferred host tree…Tree of Heaven. Arborist use our EZ-Ject Herbicide System which is an efficient and economical way to kill unwanted trees, stumps and invasive woody plants. EZ-Ject Copperhead shell controls the Tree of Heaven using the EZ-Ject Lance. Shells must penetrate through the outer bark into living phloem tissue to provide effective results. You can use it year-around in all weather conditions, including rain, unless the bark is frozen to the point of preventing shell penetration. For more information on both, click here.
