Summit Caterpillar and Webworm Control-Hose End, 1 Qt Concentrate For Insects

1st review... We bought a bottle of this each spring for 2 consecutive years (2023-24), but that was after the moth-pocalypse that took off in '21, then accelerated exponentially in '22. We were too late before we realized that those Gypsy moths (I know they are called something else now, but... 🤷‍♀️ spongy moths? I don't remember) were literally stripping ever tree in our woods with no end in sight. The whole county, in fact, has been overrun with this scourge. It was worrisome, to say the least. We have massive mature walnuts in our front yard that are one of my very favorite parts of our home and in '22 I genuinely feared they wouldn't make it when the worms ate all the leaves off them in a matter of weeks. You could hear their droppings falling incessantly on quiet spring nights. The stuff of nightmares. Anyway, in '22 we tried sticky bands, gels and sprays... We cleaned all the leaf litter in fall. You name it. But we missed the primary window in May/June to knock them down. By '23 I was ready. We treated the trees as high as we could spray. Every tree we could reach was drenched consistently. By spring of '24 when we bought more, the population had noticably declined, but was still detrimental to the trees for sure. But we did the same, treating the trees several times at the critical instar period. The moths that came out in mid summer was nothing like the plague that swarmed us in years prior. In those first years it had been like a snowstorm in summer there were so many. Fast forward to today... June 2025. The caterpillars are gone. I haven't seen a single one this spring. Maybe there's a lonely band of rebel survivors out there plotting our trees demise, but they are keeping a low profile if so. No cocoons. No moths. Our trees are fully greened out (ignore the little branches that fell in the storm a few days back. Haven't gotten to picking them up yet). Our Norway Maple has still not quite recovered from the abuse it took - it was a moth delicacy apparently, but it is clearly making its comeback. All in all, this stuff was worth it. Yes, it took some dedication on our part to treat and repeat, as well as a lot of patience. The cure took some time to spread thru the moth population unfortunately. But it worked! My beloved walnut grove lives to see another few decades I hope. If you are on the fence about this product, try it. But be prepared to continuously apply during the critical period in your particular pest's life cycle. ID the pest, buy a sprayer and get to work. And don't just expect the worms to drop dead suddenly. Thats not how BT works. At least not for us. But it did work very well and it seems to be the perfect long term solution. Edit: One sad note to add: We also have several 1000 sq ft of native plant, herb and vegetable gardens, which mostly came out of the moth-pocalypse ok, and we avoided treating anywhere near them or the beehives (for obvious reasons), but insects travel. Unfortunately these past few years our native butterfly and moth populations declined precipitously as well. Was it the BT? I can only guess. But in almost 20 years here, we've never had a shortage of butterflies, moths, and even dragon flies until now. It could be a fluke. Correlation does not equal causation, but... I thought I should mention it. We stopped treating as soon as the pest population was controlled, so hopefully the beneficials rebound. We can only provide good habitat and hope.

Excellent product

Thank goodness it worked. No more capillary’s eating my flowers!

Works very well on army worms, tomato hornworms, and any other leaf-eating caterpillars. Perfectly safe to use on veggies up to and including day of harvest. Only harmful to caterpillars. It just paralyzes their digestive system.

Two tears ago I noticed I had a huge bagworm problem on my arborvitaes. My wife and I picked all the cocoons off in the fall when the larvae was still in the cocoon and destroyed so we thought we were ahead of it. I watch the trees the next year (last summer) and it seemed okay. Until late fall when seemingly overnight several trees had severe damage and many cocoons were visible again. I purchased this product and began spraying. I mixed into a 2 gallon handheld sprayer and sprayed every 7 to 10 days through the summer to make certain I got the worms at the right stage. Trees have nearly fully recovered and no new damage noticed. The only negative is this stuff SMELLS HORRIBLE. I spray in the morning when the winds are calm and stayed up wind. If my wife is outside when I spray it drives her inside. I also like that it claims to not harm birds since there are several birds' nests in my trees.

This is a great product. I love that it is safe to use around pets, and other animals. I had a terrible infestation of bag worms in my oak tree. I picked off as many of the bags as I could but many were not within reach. A week after spraying, I went back to reapply and noticed that the remaining bag worms were dead! I was not expecting this product to work on the larvae that were inside the sack but it did. In the picture, you can see the dead bag worm caterpillar as opposed to the one on the right that is still within the sack. It does smell pretty bad after it dries so be aware. The one container also goes a very long way as you only have to mix a few teaspoons per gallon.

I bought the 1 quart concentrate. I've had bag worms the past 4 years and tried regular pesticides with little luck, they always come back the next year. I finally did some research and found that you got get these guys early. In warmer climates late May early June. Cooler climates mid to late June. Once the bags are established (2-3") it's too late, the eggs are laid for next year and the larger thick bags will protect them from pesticides. This is not a pesticide but a bacteria that works on the worms nervous system to kill them. Once I noticed the small bags forming about 1/4" I did my first spray out of the dial n spray @ 1 tsp (planting zone 7 early June) https://www.amazon.com/Ortho-Spray-Multi-Use-Hose-End-Sprayer/dp/B0071D0EZK/ I followed up again a week later. You can tell if you got them by squeezing the bags. If it's empty the worm is dead, if the worm squirts out then you'll need another treatment. The 1 quart bottle did 2 25 ft maples with enough left over for at least one more tree maybe 2.

I did sprayed our trees, cant not tell if its working, we had a lot of rain lately.
