Bonide Thuricide is a highly effective, easy-to-us
[This review was collected as part of a promotion.] Bonide Thuricide is an excellent product that truly delivers on all fronts. I used it to treat 2.5 acres of my property, and the results have been nothing short of amazing. The scent is earthy and natural—not overwhelming like some other garden treatments, which I really appreciated. The packaging was sturdy, well-designed, and very easy to open, which made the application process smooth and hassle-free. When it comes to effectiveness, this product exceeded my expectations. I haven't seen a single caterpillar since applying it, and my garden looks better than ever—no chewed-up leaves or damaged plants. Everything is thriving! What really stands out is the versatility of Bonide Thuricide. Whether you're treating a small garden or a large area like mine, it adapts perfectly to your needs. And the value? Outstanding. A little goes a long way—this one container was more than enough to cover my entire 2.5 acres. If you're looking for a reliable, easy-to-use solution to protect your plants, I highly recommend Bonide Thuricide. It's become a staple in my garden care routine.
Overall: ✅ Effective on pests ✅ Organic and garden
[This review was collected as part of a promotion.] I've been using Thuricide to help eliminate small garden pests, and it does a solid job. It's especially effective against caterpillars and other leaf-eating critters. I appreciate that it's organic, so I feel safer using it around edible plants and beneficial insects. One downside: the smell isn't great—it has a bit of a sour, funky odor, but it fades after application. It's a trade-off I'm willing to make for something that works and is environmentally friendly. Overall: ✅ Effective on pests ✅ Organic and garden-safe ❌ Smell could be better Would recommend if you're looking for a safer, natural pest control option.
Make sure you have a separate container to dilute
[This review was collected as part of a promotion.] Product does require either to have your own separate container to hook to a garden hose or you need to have a pressure sprayer to utilize this you don't know until you read the directions that is the only downfall I have I do have a greenhouse that I use it in for my garden I just started using it there is no heavy smell or odor to it which is nice because I have asthma and that would be the biggest downfall for me but this I had no issues with all in all so far without really getting into the season of my plants flourishing it seems to be a really good product
