## Overview

Summit Caterpillar and Webworm Control is a 1-quart concentrated liquid featuring Bacillus thuringiensis kurstaki (BTK), a naturally occurring bacterium that selectively targets and kills leaf-eating caterpillars. Safe for use on edible plants and organic gardens, it offers an eco-friendly, effective solution to protect trees, fruits, and vegetables from destructive pests without harming beneficial insects or wildlife.

## Description

Summit's Biological Caterpillar and Webworm Control is an all natural, organic Easy-to-Mix Liquid concentrate that kills only leaf eating caterpillars. The active ingredient is Bacillus thuringiensis subsp. kurstaki (BTK), a naturally occuring bacterium that specifically targets only leaf eating caterpillar pests of the insect order Lepidoptera. It effectively kills cabbage worm, tomato hornworm, tent caterpillar, fall webworm, Gypsy moth, and many more destructive caterpillar pests. In order to be effective, Caterpillar & Webworm control must be eaten by the caterpillar. The caterpillar soon stops feeding and dies within one to five days. The active ingredient (Btk) affects only the larval stage of susceptible insects; it cannot be used to kill eggs, pupae, or adults. Once inside the caterpillar’s stomach, where a basic (alkaline) pH is present, the bacterium releases a crystalline protein (endotoxin) that creates holes in the lining of the insect's gut. When the Btk is activated, the gut is paralyzed and the caterpillar stops feeding and dies within one to five days. Larvae are most susceptible to Btk when they are in the early developmental stages. This 100% natural alternative to synthetic insecticides is harmless to birds, earthworms, beneficial insects such as honeybees and ladybugs. It may be used on edible plants, fruits, and vegetables up to day of harvest and is OMRI® listed and approved for use in organic gardening.

Review: I would give this 10 stars if I could! - 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.
Review: Garden worms gone! Completely human safe. - 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.

### ⭐⭐⭐⭐ Good buy
*by N***E on June 14, 2025*

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.
