Monterey B.t. Caterpillar Killer
Best organic solution for gardeners protecting edible crops from pests.
This organic concentrate is the gold standard for stopping caterpillars and worms without nuking your entire garden ecosystem. It requires the extra step of mixing your own solution, but that precision allows you to treat only the affected plants rather than blanketing your vegetables in harsh chemicals.
