Does it change color over time?** A: Thuricide is a fairly thick hunter green color and mine has never changed color. 'Course, I don't keep it any longer than the current growing season. Once you dilute it to spray, it's only active for up to 12 hours but I've never trusted that time frame so always use it within a couple of hours. Does a terrific job of wiping out the caterpillers! We haven't had a tomato hornworm in the veggie garden for 4 years and there has been no harm to anyone who eats the tomatoes! My flowers no longer look like "lace" from caterpiller damage. I highly recommend it! **Q: How long does one application last?** A: Application will last until rain unless using on herb plants can use till harvest **Q: I know it says, "safe for all plants", but I've used products with the same claim before, w/detrimental effects, on atropa belladonna. Anyone?** A: This is a biologic so I can't imagine it hurting anything but the caterpillars. I would trust the label and follow the directions. On the other hand, fungicides, which BT is not, can be harmful to some plants such as begonias, but as this is a bacteria that is only active for a few days it probably can't harm any plant **Q: How effective is this product on fungus gnats?** A: It worked well. I sprayed twice. ## Frequently Bought Together - Southern Ag 100520028 13021 Caterpillar Control, 8 oz - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - Bonide Captain Jack's Deadbug Brew, 16 oz Concentrate Outdoor Insecticide and Mite Killer for Organic Gardening --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/13183077-100520028-13021-caterpillar-control-8-oz](https://www.desertcart.co.za/products/13183077-100520028-13021-caterpillar-control-8-oz) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-06*
