SUMMIT 021-6 Caterpillar and Webworm Control-Hose End For Insects, 1-, Quart, White

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.

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.

This product was easy to use and covered more than I expected. The coverage was great but gradually turn your hose on because the speed was powerful! Seemed to work well and definitely cut back on the number of bugs, we live in a very wooded area.

Big invasion this year of bag worms. Tried neem oil, not so great, worms remained and trees were still being eaten. Based on other reviews thought Id try this stuff. Am sure glad I did. Instructions said: spray weekly or after a rain. OK, after first spraying caterpillars mostly disappeared from my Mountain Laurels and my front porch. After second spraying no more bag worms or caterpillars. WOW. Note: I bought the version with the attached sprayer as it has the range to reach the top of my trees. Works well, I recommend it.

Great sprayer for sod web worm. Easy & effective.

I gave it a 3 star because it worked for about a month and half and the web worms were back. Just spray them down and remove them.

Death came swiftly.Sprayed this on my Liquid Amber tree at dusk like a suburban vigilante, and by morning... caterpillar carnage. No more poop, no more chewed leaves—just peace. Highly effective, and oddly satisfying. Started working in under 24 hours on my Liquid Amber. I noticed it had little black/green caterpillars. The tree is taller, and pretty full, so the hose tip did not reach the top, but I'll continue to treat, and enjoy the fruits, or dead caterpillars, of my labor.

THANK-YOU THE ONLY PRODUCT THAT WORKS !!!!!! We have battled army web worms on our lawn in Florida for a decade. Even hired expensive professionals. THIS is the first time we have controlled them and now have a luscious healthy lawn. Follow the directions and re-apply in 5 to 7 days to get their reproductive cycles. I did this four times and after 4 months I am web sod ( army worm ) free until the next invasion. We have a puppy so going organic is paramount.
