My plants are thriving!
Great stuff! Totally works! My outdoor plants had bud worms everywhere. They looked like skeletons, sticks and twigs. The worms were eating all the buds and the leaves had holes. Now, after using this product, the life has come back and new buds are showing. My only regret is that I didn’t use it earlier in the season! Next year, my plants are going to be spectacular with this product!

5.0 out of 5 stars Works better than chemical spray
Reviewed in the United States on October 7, 2019
The spray works great, easy to use. My garden was heavily infested by cabbage looper and a few types of army worm. I tried a chemical treatment, after twice sprays, the caterpillars were still there. I did some researches for natural treatment and tried diatomaceous earth, which didnt work. I finally found this Bt bacteria spray. It worked like magic! After the first spray, I noticed the veggies didnt get more holes. I found a few worms that looked like they were intact, but they also didnt cause more damage. I sprayed 3 days later after seeing some new, little caterpillars appeared. Then my garden was good up to now, which is 2 weeks after the first spray. I sometimes found 1-2 worms, which may be luckily to not eat the treated leaves last time (picture is the little guy I found today, I sprayed Bt directly on to him and he stopped eating). I used about 1/3 of the bottle to treat my whole small garden, which is on 5x10 foot. So this spray is a little bit pricey to use on large scale garden, but for my back yard planting, it is just fine. Another downside is this spray smell horrible, like stale food.
