    Is there some place around Edmonton, Alberta ,Canada where I can purchase Lepitect? Any help you can give me is greatly appreciated.

    Thank you

      Unfortunately, Lepitect is only labelled for soil injection or foliar spray application for tree pest insects. Any other use of the product would be considered off label, and therefore against the law.

    • The Tree Geek says:

      All of our Acephate products are specifically labelled for use on trees or landscape plants, any use other than what is covered on the label is against the law.

  2. edhenj says:

    Can I use a Ross Root Feeder with hose to apply the soil injections for redwoods 20 inch DBH.
    Should the injection be near the base or crown of the tree or near the drip line?

    • The Tree Geek says:

      That shouldn’t be an issue from a label perspective, as it is technically a soil injection. The only concern I would have would be putting the correct dosage through the device. If you can make it work following label directions for dosage, then you’d apply it at the base of the tree.

  3. Sean snider says:

    Can I just pour the solution on the ground for the tree to uptake? What is the difference between the two packs, one says infusible. Seems like the much better deal is the 20 pack but I’m concerned about infusible..

    • The Tree Geek says:

      Hi Sean, Lepitect is only labelled for soil injection not soil drench, and requires the user to inject into the soil rather than pouring it around the base of the tree. Lepitect infusible carries label language that allows for direct trunk injection.

    Your article on Japanese beetles is one of the most accurate I’ve seen. I was very unpopular at a gardening centre last week when I stopped a customer from buying the Japanese beetle traps by explaining this same logic. I think the owner should be embarrassed to be selling them!! Anyway in ontario canada I do not believe we can buy this product you recommend but something must be offered soon or our trees will die won’t they? My lovely mountain ash and sand cherry are being brutalized for the 3rd year. Not sure what to do! I’ve pulled up all my roses hoping they would make the yard less attractive but the mountain ash seems to be hit the worst. So sad and not sure how to manage this voracious pest! Once in my tree they then move through almost every plant and flower. My neighbours had lots of those stupid traps a few years ago and I’ve tried explain why not to buy them….. Hoping the governments in canada and US are looking for solutions??Any advice?

    • John Hillis says:

      Glad to hear you are spreading the knowledge! Unfortunately, I am unsure of the status of Canadian regulations. I would look to local stores or distributors for products with the active ingredient of acephate, or imidacloprid, (if your trees are wind pollinated), as to not harm pollinators in the process.

  5. Dennis Feerrar says:

    How would you apply to trees in Pennsylvania, do you need to drill into the tree, or just put it around the base?
    Can this product be shipped to Pa.

    • The Tree Geek says:

      Hi Dennis,
      For Lepitect Infusible, you need to apply it as a trunk injection where you would drill into the tree. The regular Lepitect needs to be applied to the soil with a type of soil injection system, and yes this product can be shipped to PA.

  6. david baratta says:

    i see that this is labeled to work with brown tailed caterpillars. i have several 3 foot diameter oaks in southern maine that have lots of nests in the high canopys. how effective is this product on brown tail? is trunk or ground more effective? does one work faster?

    • The Tree Geek says:

      Hi David,

      Lepitect should do the trick with browntail moth. You will want to treat before may to kill caterpillars before they start growing the irritating hairs. It will still work afterwards, but you will have dead caterpillars with irritating hairs on them. Both types of product work well, and the uptake for the soil applied is fairly quick taking about 3 days to about a week to get up in the tree. The soil applied does need to be applied with a type of soil injector according to the label, so for either product you would be looking at purchasing some equipment as well if you do not already own them.

  7. Jason says:

    For browntail moth caterpillar control done on oaks in the spring, what effect might Lepitect have on the acorn crop and the wildlife that feeds on them? I guess I’m asking two questions: How long does the Lepitect remain effective in the tree, and will it persist until the fall and contaminate the acorns? We’ve got huge oaks that are being ravaged here in ME, and lots of caterpillars in the yard. Winter clipping will be difficult because of the trees’ height, so I’m researching pesticides which on principle I’d rather not use at all. Tough situation. Thanks.

    • The Tree Geek says:

      Hi Jason,

      Lepitect will work for browntail moth and it breaks down after about a month to 45 days, so it should cause any problems in the fall.
