The two most effective ways to kill Spotted Lanternflies are with either soil injection or bark treatment.
We typically recommend the soil injection treatment for a few reasons. It’s a proactive approach that protects your trees from damage, does not harm non-target insects, and only combats insects feeding on the tree.
Soil injection is a low volume application, applied by evenly injecting the soil in and around the tree. We shoot water and the chemical into the ground about six inches down. We stay inside the drip line (the edge of the branches), the roots then start to absorb the tree. This treatment protects your trees from the Spotted Lanternfly feeding and further damaging your trees.
Keep in mind this treatment does not immediately kill Spotted Lanternflies. It takes up to 3 months to get inside the tree before it is effective.
This is why the soil injection treatment is best in the fall, and early spring - to get active control right away!
The other type of treatment is the basal bark treatment. This is where we spray from the root flares, all the way up to about 5 feet in height. We spray all the way around the tree with a low volume either pressure sprayer or backpack sprayer.
This treatment allows the tree to absorb the chemical through the bark. You can think of this as rubbing hand cream onto your skin until it soaks through. This is basically how the basal bark application works on a tree. It will absorb slowly throughout the tree over the next week.
The Spotted Lanternfly will then stick its needle into the bark and start sucking the sap out of the tree. As the insect feeds on the poison in the sap they die. This treatment will generally last about 3 months.
The great thing about the basal bark treatment - is that it has an immediate impact on the tree! Within 24 hours, you’ll see massive kills of Spotted Lanternflies.
After you fill out a short questionnaire, we can help you choose what treatment is best for your situation. Treatment suggestions depend on the time of year and your specific needs.
