Product Overview

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

Multi-Insect Killer Tree Injection Kit (formerly Pointer) is designed to allow homeowners to effectively treat trees of any size with systemic insecticide. It is especially useful in situations where foliar spraying is not feasible. Controls Adelgids (including Hemlock Woolly Adelgids), Aphids, Asiatic Garden Beetles, Black Vine Weevil Larvae, Chafers, Elm Leaf Beetles, Eucalyptus Longhorned Beetles, flathead borers (such as Alder-Birch Borers, Bronze Birch Borers and Emerald Ash Borers), Japanese beetles, Lacebugs, Leafhoppers, Leafminers, Mealybugs, Oriental Beetles, Psyllids, Royal Palm Bugs, Soft Scale Insects, Thrips (suppression) and Whiteflies on all types of ornamental trees. In general, one application gives season-long control and control of pests can start to be seen within two weeks.

Multi-Insect Killer contains an insecticide that is deposited into holes drilled into the tree trunk at the root flares (where the trunk begins to 'flare out' at ground level). This simple application method is both easy and convenient. Also, damage to the tree is minimized due to the needle-like design of the ampules.

Timing of Treatments
Treat trees anytime during the growing season. Treatments earlier in the growing season are more successful. As a preventative, apply in early spring prior to insect activity in the tree; one application provides full-season control. To kill insects already on a tree, apply in spring through fall more than one application may be needed depending on the infestation.

The active ingredient is Merit® (Imidacloprid).

How Is It Applied?
Use the syringe to deposit insecticide into holes drilled around the base of the tree.

Measure the circumference of the tree within 12 inches of the ground. Drill 1/2-inch-deep holes into the tree at the flare of the roots. Evenly space holes around the tree every 4-6 inches. Inject prescribed amount of insecticide into each hole.


How Much Do I Need?
One Multi-Insect Killer Tree Injection Kit contains enough insecticide for 15 application sites and can treat from fifteen 4" circumference trees to one 60" tree.

  • Injections to conifers may be either slow in uptake or have no uptake at all.
  • Even though Multi-Insect Killer Tree Injection calls for very small holes to be drilled, all holes are wounds. Holes should not be drilled in a tree more than once a year. Holes should also not be drilled in more than two consecutive years.
  • As with all pesticides, be sure to read all product labeling carefully before use.

    Worked For Me!

    Posted by Joseph Schweigert on 8th Sep 2014

    We have two white ash trees on our property here in Upstate NY. We are surrounded by other ash trees, most of which are infected by ash borers. Both trees on our property were showing signs of advanced infection (small leaf production, leaves never turned the deep green that is usual, dead branches, etc.). I applied this product in mid August of last year, when the trees were in really poor shape. This year we saw a 100% improvement in their appearance - to the point that I hired an arborist to come in an take a look at them. He climbed into both trees and said they looked much better but, because they were still infected up near the crown, recommended we get them treated with ArborJet as a follow-up to this treatment. I thought sure I would be taking them out this year but, thanks to this treatment, I was able to get another year of successful growth from them.

    Roger's review of MIKTIK

    Posted by Roger G Keen on 18th Sep 2013

    I applied the product late in the growing season so can't tell from the appearance of the tree wether it is working or not. Next year will tell.
    The product is easy to apply although a one inch hole does not take the hole dose allowed, there was some run off.
    I notified the town of Milton about this product and have had conversations with the councillors. The main drawback is it does not biodegrade so multiple usage over large areas would cause contamination of the bio system and possibly get into our food chain or water.
    One time use to save the tree is not so bad, but long term use could be a hazard. A biodegradable product would be safer although at this stage, more expensive.

    Easy to use

    Posted by Unknown on 6th Sep 2013

    Easy to use. Had someone tell me that the drill to drill the 1/4 inch holes should be a special sharp drill that does not close off the pores in the "arteries" that carry the "medicine" up to the top of the tree where the bronze birch borers are doing damage. Would like a recommendation from the company regarding this. **FROM TREEHELP: A sharp bit is certainly preferred to a dull one, but no special tool is typically required. **

    Awesome for Aphids

    Posted by Unknown on 30th Jul 2013

    We have a tree that each year gets Aphids and they drop a disgusting sticky substance on our cars. This product worked great and we have been free of Aphids and their mess. My husband was able to drill several holes and inject the tree. It was fairly simple. Next year we will have to do the drench so we do not drill the tree again. I called and spoke to a representative at and he was very imformative and helpful. He let me know that we could drill the tree this year but that the drench would be better for next year. I definitely recommend this product to anyone having a difficult time getting rid of aphids.

    Favorable Report

    Posted by Unknown on 23rd May 2013

    I used this product last year on Horse Chesnut tree which was attacted by a Leaf Miner
    I did not inject it until after the flowers had died as I did not want to affect any pollinating insects such as bees and bumble bees. The Leaf Miner effect was quite bad when the porduct was used but seemed to prevent the progression of the infestatin and the leaves stayed on the tree until the normal time albeit damaged.
    The tree this year seems much more healthy and Iam stil deciding whether a treatment this year is necessary.
    I have concerns that the chemical may affect tree health especially with continued use but it does not seem to have adversely impacted the tree after one use In fact the tree seems very healthy this spring.
    I would recommend this product on my limited use. I would advise to ensure that the product is not used until the pollinators have finished on the flowers
