    Dear Sirs;

    Is there any insecticide I ca use to protect my ash trees from the emerald ash borer in N.Y.S. ?

    Thank You, Stephen Shea

  2. The Tree Geek says:

    Stephen, unfortunately in the state of New York, homeowners have to contact a professional for emerald ash borer treatments. Both Xytect and Transtect are registered in the state, but a pesticide applicator license is required to purchase them.

    I have flying insects eating my poplar trees. I live in Bastrop, Texas. After the fire of 2011 we planted some poplars. Now they are being eaten by flying insects about 3/4 of an inch. What can I use to get rid of them

  6. Cheryl Meigs says:

    Is Transtect the best product to use on large maple trees to control gloomy scale? When is the best time to apply a tree drench for gloomy scale? I live in coastal North Carolina.

  7. Nancy says:

    If I apply Transtect to the ground at the base of my pinon pine trees now (end of May), will it be damaging to any birds who may have built nests in the trees?

  8. Nick says:

    I have 5 Jacquemonti Birch, 3 stems each. Planted them last year as screening in my yard. This past weekend I re-mulched around the trees and noticed one stem had a hole with some sort of waste product on ground next to hole. Seems it could be the bronze borer. I have not seen any damage elsewhere but want to make sure they don’t spread.

    What can I use as treatment now in July and how quickly will it work?

    • The Tree Geek says:

      Hi Nick, Bronze Birch Borer would typically have a “D” shaped exit hole. If you aren’t seeing any die back in the tree (a tree suffering from BBB would have wilt like symptoms starting in the top of the canopy and moving downward), then it could be a native borer species. If you could snap a photo of the overall shape of the tree and a close up of the exit hole and send it to info@thetreegeek.com, we’d be happy to take a look and let you know what we think is going on and what you can do about it

  9. Lynn says:

    My river birch trees are covered in European hornets eating the bark. I have read dinotefuran is effective. Have you had any experience with this use of your product and if so what is the most effective application?

    • The Tree Geek says:

      Hi, Lynn. Our dinotefuran formulation is not labelled for use on that particular pest. Sorry for the inconvenience.

  10. Michael Kenny says:

    hi, I have wood borers in my pin oak and I was wondering if you have anything to get rid of them. I live in Lancaster pa. Am I allowed to use this product in pa. Any help would be greatly appreciated. Thanks Michael Kenny

  11. Ann says:

    I live in NJ and and my hemlocks have scale. The trees are 25′ – 30′ tall. Can I use Transtect or Xytect 2F to treat them myself or do I need to have a certified arborist apply it? How is it applied? I can’t spray in the community I live. Is it safe? Is there any chance of it being airborne? The trees are close to my property line (30″ – 34″) and the neighbor. Does it make any difference if I apply it now (in the Fall) or the early Spring?

    Thank you.

    • The Tree Geek says:

      You can most definitely use both of those products to treat scales on your Hemlocks. Both would be applicable as soil drenches, meaning you wouldn’t need to spray them, so there is no chance they become airborne. For Xytect, there is no difference if you apply now or in the spring, for the Transect, you’ll want to apply closer to when the crawler stage of the the scale is emerging, meaning late next spring.

  12. Ann says:

    Dear Sirs:

    I live in NJ and have scale on my hemlocks. They are 25 – 30′ tall and are buffer between my house and a neighbors. Can I treat them myself or do I need a certified arborist to apply it? Which do you recommend I use: Transtect or Xytect 2F? Does it make a difference if I do it in the Fall or the Spring or should I do Transtect in the Fall and Xytect in the Spring? It is safe? Is anything airborne? I have 30″ – 34” to my property line close to neighbors. Please advise. I do not want to lose them.

    Thank you for your expertise. (Resending, not sure my last comment went through.)

  13. Denny Taylor says:

    I have lost two 15 foot arborvite trees and am losing two more from scales. Took samples to local agency and scales come up under microscope and I am asking if treated now , Oct. can I save the trees that have been infected. I already spray for mites and bag worms and fungus but this just happened this summer, I planted 53 trees for a wind block and have a;ot of money invested can I use transtect to save the ones already inffected and how long does it take to kill to scales and do I use it yearly . Thank you for any help you can give me

    • The Tree Geek says:

      Hi Denny,

      Thanks for the question. You most likely can treat for the scales at this time of year, but it depends on what kind of scales you’re dealing with. Soft scales will be controlled by either Optrol or Xytect. Hard scales will require Transtect.

      I hope that helps! Please email with more questions.

  14. Donnie Rogers says:

    Hello Tree Geek,

    I live in Indiana and have a Silver Maple that has Lecanium Scale and Black Tar Spot on the leaves. Will the treatment of Transtect also take care of the Black Tar Spot?

    Thanks.

    • The Tree Geek says:

      Black Tar Spot is a fungal infection of the leaves. In most situations it causes only visual damage and does not harm the health of the tree. Recommendations for management include pruning to increase air flow in the tree canopy, removing and disposing of fallen leaves, and also redirect sprinkler systems to not directly spray water on the leaves. In severe cases, fungicidal sprays at leaf emergence in springtime can be effective.

  15. Sandy Tillman says:

    I have an 8 year old oak tree(pin) that has been diagnosed with oak scale. The estimate for injection treatment with Safari/Merit is for $225.00, do you think that is a fair price? Also can this be done by homeowner?

    • The Tree Geek says:

      Hi Sandy. Depending on the size of your tree you could treat your Oak yourself for cheaper than the injection estimate, though I think that the price quoted is probably fair for a tree company to do the work. Transtect is the same active ingredient as Safari, and Merit is the same active ingredient as our Xytect 75WSP. If your tree is smaller than 20 inches you could treat it yourself for about $185.00 (based on current prices as of 5/12/15). Transtect and Xytect 75WSP can both be applied as a soil drench, which is a very simple and straightforward way to deliver the active ingredient to the tree’s system. I’d put the Transtect down now, and then do the Xytect in the fall, which will give you season long control next year. Scales can be very difficult to control, so keep in mind that you may need to repeat the treatment cycle for a few years in a row to get an acceptable level of control of the scale insects.

  16. Maureen says:

    It is mid-May in Maryland and we need to treat holly leafminers on several trees in our woods (which are close the marsh and less than about 200 yes to the Chesapeake). What treatment will be most effective against leafminer but least damaging to beneficial insects, marsh and Bay creatures, and birds? Thank you.

    • The Tree Geek says:

      Hi, Maureen. I think your best bet to take care of the Leafminers is going to be a soil applied treatment with Transtect. Soil application will mitigate much of the risk of accidental application of insecticide to the nearby bodies of water, and Transtect will be very effective against the Leafminers, as well.

  17. Alia says:

    Hi, I’m located in Long Island, NY and I have purple/red leaf plum trees that are infested with scales. There were white eggs but now seem to hatch and it’s past the dormant stage, can I use this product on the scales? The tree hardly produced ay flowers or leaves this season. Is toxic to children? The trees are near my pool. If this can’t be used, can I make a mixture of soap and water to suffocate them? We do this to our pine tree that has these worm types and it kills them. Or I use soap, water and alcohol to kill the palm scales on my indoor palms. Any information would be great. Thank you!

    • The Tree Geek says:

      Use transtect as a soil drench around the base of the tree. It is very effective against scales, and will not impact your pool.

  18. Jerry says:

    I live in Ct and have previously lost a clump of white birches to a borer of some sort. I again have the same pinholes and dying branches but not at the top. Can I use Transect at this time of year to prevent further damage and lose the trees again? I don’t know the specific species of white birch.

    • The Tree Geek says:

      Unfortunately, it’s a little late in the season to get effective control with systemic pesticides. You’d be better off waiting until spring and treating with Xytect 75WSPonce the ground thaws. The best thing you could do now is to make sure the tree is getting plenty of water, and if it’s planted with turf grass right up to the base, you should consider removing the grass and mulching a ring 5 or so feet out from the base of the tree. Birch trees love water, and a lack of water can make them more susceptible to disease and insect pests.

  19. Julie says:

    My Austrian pines appear to be infected with pine needle scale. Is there anything I can do at this time of year to start clearing it up? Thanks.

    • The Tree Geek says:

      Unfortunately, not right at this moment in time. If you wait a little bit later into the dormant season you could spray the tree with an application of Horticultural Oil. Otherwise, your best bet is to wait until next spring and apply Transtect.

  20. KD says:

    Hi – first thank you for a great site! Our 15-20 ft tall magnolia tree appears to be it with magnolia scale, this is the second year we are seeing it, and its spread to almost every branch, lots of wasps getting attracted, which would make foliar spraying very difficult. Can we use Transtect to treat the magnolia? Is there a particular time to use Transtect or we can do it now? We are in Cincinnati.

    • The Tree Geek says:

      Hello,

      Yes, you can use Transtect, and I would apply it around late June/early July. I would also recommend a dormant horticultural spray in the fall or spring also if the infestation is really bad.

  21. Joel says:

    Does Transtect and Xytect Treat the same pests/problems (With the only difference being Transtect has the quick uptake? If so, what are the pros on Xytect over Transtect? If not, What does one treat that the other doesnt?

    • The Tree Geek says:

      Hi Joel,

      There are some differences between the two besides uptake time. There is some variability, but in general Transtect has a residual of 2-3 months while Xytect has a residual of one year when applied to the soil. Transtect is also better at treating for armored scales then Xytect. Timing can play a factor as well. Sometimes, Transtect is used after flower drop when a quicker uptake is needed to reduce risk to pollinators. Knowing the pest you are treating for is the best bet for deciding between the two.

  22. Ellen Whitford says:

    Re. Birch borers: It seems early, but I saw new evidence of emerging beetles already on 3 trees I didn’t know has been attacked. In fact, found two borers. This makes me I think I should apply faster-acting Transtect. Do you agree? Problem: Soil here is still very, very, very wet (record rains in February and still raining most days)…. can I still apply or do I need to wait?

  23. ellen whitford says:

    I’m in Seattle and really confused about the timing of when to apply Transtect. I had initially thought I would apply Xytect in early March, but it’s been incredibly wet here (record rains in February) and it’s still wet, so I’ve put it off.

    However,. I just removed one birch that lost about a third of it’s canopy late last summer due to borers. (I had it removed last week), and when inspecting the remaining 5, I see what I think are NEW borer holes on one and I found actual borer beetles on two others. Awfully early for beetles, isn’t it? I’ve already got Xytect which I ordered last winter and haven’t applied. But maybe I should use Transtect on these 5 trees? I’m worried because the borers already seem to have emerged! Should I go ahead and apply as soon as an order arrives? Or should I wait a little later into mid or late April? Any advice you can give me about which chemical and the timing would be much appreciated!
