    Monterey Insect Control iWorks

    Posted by John on 15th Jan 2021

    Our 40 foot River Birch trees would die at the top then within the year be totally dead. Checking further after losing two we found out we had some type of leaf miners it would leave white scaled eggs. Last year I treated as directions and we had no issues. The river birches had their best year in awhile. I think it did the trick. I would recommend and make sure you do it before spring.

    still losing leaves on locust tree

    Posted by Unknown on 15th Jun 2014

    I had a tree specialist representing a large company tell me the reason my honey locust loses individual green leaves is spider mites. I thought I had read the product would take care of mites so I bought it. Green leaves started dropping on 6-13-2014. I am so disappointed.

    Shade is back!

    Posted by David on 5th Jun 2013

    I have about a forty 40 year old Silver Tip Maple tree that was looking pretty bad. Ends of branches dying back as well as a canopy that seemed to be getting thinner every year. I had fertilized it a couple times in the past 3-4 years but it STILL did not seem to be looking to happy. I applied this once a year drench in a last ditch effort as I was even starting to think about taking the tree down. It really turned it around and the tree is looking the best it has in years!
    In fact I am so happy with the results I am now applying this product to several other Ash trees I have that are not looking as good as in years past.
    Great product! THANKS!

    So far, so good! After 2 years of easy, but effective treatment, our ash tree is standing tall and healthy. Hope that it continues!

    Worked like a charm

    Posted by Sam Carlsson on 1st May 2013

    Used the drench only one time before this; it performed exactly as promised. No oyster shell scale during the growing season.
    Easy to use, so i expect similar results this time.
