Spotted lanternflies are invasive insects that can cause significant damage to crops, trees, and other plants. If you have spotted lanternflies on your property, it’s important to take steps to control their spread and minimize the damage they can cause.

There are several professional services that are very effective in spotted lanternfly control. These services typically use a combination of techniques, including insecticides, traps, and physical removal, to control the spread of this invasive and destructive insect

When choosing a spotted lanternfly control service, it’s important to look for a company that is licensed and experienced in dealing with this specific pest. Arbor Care Resources is fully licensed and has years of experience in assessing and treating affected trees and properties.

Soil Drench and Soil Injection

Soil drenches of systemic insecticides are applied into the soil around the trunk of the tree. The insecticide is taken up by the roots and moved into the rest of the tree. Ideally, soil drenches work best when applied in the early summer to trees that had high Spotted Lanternfly (SLF) populations in the past and are likely to have them again. To protect pollinators, soil drenches of systemic insecticides should be applied after a tree’s flowers have faded. Soil injection by plant health professionals with specialized equipment can provide a more precise application than soil drenching, but it also relies on applying a water-soluble insecticide to the root zone of an individual plant. Little efficacy data from soil drench or soil injection applications of imidacloprid to control SLF is available. The insecticide needs time to be taken up by the tree roots, giving this method the greatest time delay until it begins to kill SLF. Dinotefuran soil drenches tend to be taken up and provide efficacy much faster and more consistently than imidacloprid, but they are less precise than trunk sprays or injection. The amount of water needed to carry the insecticide into the tree is also very important. It is recommended that a soil drench of imidacloprid be applied in the spring (post bloom) and dinotefuran be applied in midsummer through September to target adult SLF. Read the label carefully and follow the directions to achieve the best results. Foliar Application

Systemic Bark and Trunk Injection

Spotted Lanternfly (SLF) death has been observed in less than 24 hours after injecting a tree with dinotefuran. Injections of imidacloprid have also been successful but take longer to become effective. Trunk injection can provide the most accurate dosing of a tree, often with the least amount of material used, as very little material is lost to the environment outside of the tree. Products labeled for trunk injection may not have restrictions of volume of active ingredient amount per acre per year and can allow more trees per acre to be treated without violating the label restrictions. Be sure to follow the insecticide label and equipment manufacturer’s instructions. As with other application methods, the environmental conditions and vascular health of the tree can greatly affect the translocation speed of the insecticide.


Systemic Trunk Spray

Trunk sprays (also referred to as “bark banding” or “bole sprays”) with dinotefuran have also been successful. Observed death of Spotted Lanternflies (SLF) may take longer by trunk spray than with injected applications but is still likely to occur within a few days of treatment. If the label requires a bark penetrant as a spray adjuvant, be sure to include it in your application. It is important to properly dose the trees based on size measurement, not simply “spray until runoff.” It is often necessary to pause the application to wait for the material to be absorbed so the full dose as dictated by tree diameter at breast height (DBH) may be applied. Large trees with exfoliating bark, such as mature silver maples, may be difficult to properly treat with this method because the bark can reduce the penetration of the insecticide into the living tissue. Additionally, trees that have a compromised vascular system (i.e., are wounded) may not be able to translocate the insecticide as well as other trees.
