Compare-N-Save Systemic Tree and Shrub Insect Drench - 75333, 1 Gallon

I've been buying this for the past 7 years or so to protect my ash tree from emerald ash borers. My now 25-year old tree was definitely hit, I can see scars, but it is alive and doing pretty well while all of the non-treated ash trees in my town have died and been cut down. All of the untreated trees are gone. On my tree probably 95% of the canopy is alive. Anyway, this product is currently unavailable (I just came to buy another gallon for next year) but look for something with the same active ingredient, imidacloprid, 1.47%.

A belated review - we bought this probably 6 years ago. It still works great to kill stuff right down to the roots. Same as RoundUp but cheaper - check the percent of active ingredient.

HELPFUL INFO: I found the product info to be insufficient in the listing, as I had no direction on how much product I would need. The water:product ratio is simple, and could easily be in the listing, to help customers with an estimate of gallons needed! I highly recommend pre-measuring the tree trunk(s) to be treated, especially if you have several, and noting them in a similar fashion as I've pictured. Then do the math!The breakdown is easy: 1 ounce of product per 1 inch of the diameter of the tree trunk (at chest height). Or, 3 ounces per foot of shrub height. These amounts are added to 1 gallon (or 2) of water, and simply poured right around the base of the trunk.Needless to say, I'll need far more than 128 ounces (1 gallon) to treat the multiple trees in our yard.** I'll update my review in a couple months, allowing enough time for aphid elimination, based on the absence of honeydew all over our deck and outdoor furniture.UPDATE: It's obviously been more than a couple months. The product does work. But I also learned that application is necessary in the early spring (April) so that the tree has sufficient time to take-in the product prior to the start of aphid activity. Otherwise the aphids get a head start, damage begins, and you're playing catch-up the rest of the season. Today is April 2nd, and I'll be retreating no later than the middle of the month.👍🏻

Last summer, from mid July through Fall, we couldn’t use our yard because it was a sticky mess covered in mold, wasps and ants, all from these darn pests. This summer, it’s now July 24 and I don’t see anything but dead nymphs. I am hopeful we have reclaimed our yard for our beneficial use again.I used this to treat a giant wall full of Boston Ivy, 5 Ailanthus trees (Tree of Heaven, aka Spotted Lantern Flies’ favorite food!) and a giant Paulownia tree (Empress tree). I applied exactly per the instructions on June 6th. It’s now July 24th and I have hundreds of dead SLF’s all over the yard here in Brooklyn, NY. I can see hundreds but I am sure there are many more. The dead ones are late stage nymphs and don’t have wings yet so I’m hopeful that means I also won’t have 10 million eggs to hunt over the winter. This past winter I found and destroyed probably over 150 egg clusters and then caught likely over 1,000 nymphs on sticky tape in April and May but I’m wondering if any of that was necessary given how effective this pesticide has turned out to be.With that said, I’d love to apply less of this so I’ll have to see next year if I can scale back the dose and have it still be as effective. I’m worried about unintentional harm to birds and other beneficial insects so ideally I can cut the dose.

For anyone currently infested with cicadas (May 2024) use this product to stop them. I find their exoskeletons at the base of treated trees but I hear none of that noise they make in treated trees.The tree on the left side was treated. They migrated to the untreated tree on the right. Dramatic and impressive!woolly aphids "honeydew" rained from the trees. That's got to be the most polite word I've ever heard to refer to crap. Due to indirect sunlight, I saw it pouring out of the trees from a gazillion aphids and from that point, I wore a hat. It covered *everything* black - my garden ornaments and flowers, truck, car, lawn. I had to park my vehicles in another part of the driveway out from under the trees. Because I'm not fond of scrubbing insect poop, each year I waited for spring rains to clean my lawn ornaments.I researched products and decided on this insect drench that I bought December of 2019. I also read reviews and decided to use the 10 oz. per tree. Not exactly the amount as recommended by others but I was not going to measure out 9.anything. Some of the trees are old with a circular span of 60+". I used 10 oz per tree no matter its size.What is the point of writing a review right after buying this just to say I'll be back in a few months with the result? So the results are in: Amazing. Awesome. Any superlative I can think of, insert here.I treated in January and June and for the first time in five years, I will see my tree leaves turn color with the fall instead of blackened and mowing them all over the yard in August. I haven't had to scrub "honeydew" off my truck so I can see out the windshield and my car is still white. I'll treat one more time in January just to show the little buggers I mean business if any new ones move in.
