Multi-Insect Killer Tree Injection Kit

The Multi-Insect Killer Tree Injection Kit (formerly Pointer) lets homeowners treat trees of any size with a systemic insecticide injected at the root flare. One application generally gives season-long control of borers, adelgids, aphids, scale and other pests on ornamental trees.

Not available for sale in New York State.

Contains a 0.5 fl. oz. (15 mL) vial of injectable insecticide, one syringe and one syringe tip. Treats 1 large tree (60 inches in circumference) or numerous smaller trees.

What does it control?

It controls these pests on all types of ornamental trees:

• Adelgids, such as hemlock woolly adelgid
• Alder-birch borer
• Armored scales (suppression)
• Aphids
• Asiatic garden beetle larvae
• Black vine weevil larvae
• Bronze birch borer
• Chafer larvae
• Elm leaf beetles
• Emerald ash borer
• Eucalyptus longhorned beetles (borers)
• Flatheaded borers
• Japanese beetles (and larvae)
• Lace bugs
• Leafhoppers
• Leafminers
• Mealybugs
• Oriental beetle larvae
• Pine tip moth larvae
• Phyllophaga spp. larvae
• Psyllids
• Royal palm bugs
• Soft scale insects
• Sawfly larvae
• Thrips (suppression)
• White grub larvae
• Whiteflies

The active ingredient is Merit^® (imidacloprid). It is especially useful where foliar spraying is not feasible. In general, one application gives season-long control, and you can start to see results within two weeks.

How is it applied?

The insecticide goes into holes drilled into the trunk at the root flare, where the trunk begins to flare out at ground level. The method is easy and convenient, and the needle-like design of the ampules keeps damage to the tree to a minimum.

• 1. Measure the circumference of the tree within 12 inches of the ground.
  
• 2. Drill 1/2-inch-deep holes into the tree at the root flare, evenly spaced every 4 to 6 inches around the tree.
  
• 3. Use the syringe to inject the prescribed amount of insecticide into each hole.
  

When should I treat?

Treat any time during the growing season; earlier treatments are more successful.

• As a preventive: Apply in early spring, before insect activity in the tree. One application provides full-season control.
• To kill insects already on a tree: Apply from spring through fall. More than one application may be needed, depending on the infestation.

How much do I need?

One kit holds enough insecticide for 15 application sites and treats anything from fifteen 4-inch-circumference trees to one 60-inch tree.

What else should I know?

• Treatments are more effective early in the growing season.
• Do NOT apply this treatment to food-bearing plants.
• Injections into conifers may be slow to take up or may not take up at all.
• The holes are very small, but every hole is a wound. Do not drill a tree more than once a year, and do not drill in more than two consecutive years.
• Read all product labeling carefully before use.
