As an avid gardener and someone who enjoys growing my own cannabis, I recently received a comment that prompted me to create this review. The comment was about a previous review where I mentioned using Monterey Garden Insect Spray (Bacillus thuringiensis) to control worms on my cannabis plants. The person was concerned, thinking BT was a harmful chemical pesticide that would make the cannabis unsafe to smoke. This misunderstanding inspired me to explain what BT really is and why it’s actually a safe and effective solution for pest control in organic gardening.
Monterey Garden Insect Spray is not a chemical pesticide, but a biological insecticide, which means it’s made from natural bacteria, specifically the subspecies Kurstaki. This bacterium is highly effective at controlling caterpillars and other invasive insects without harming the plants or humans. In fact, BT is approved for use in organic gardening, highlighting its safety and natural origins. I always make sure to spray BT on my plants before the buds form to prevent any damage from caterpillars. This approach ensures that the plants remain healthy and free from pests throughout their growth cycle. One of the most reassuring aspects of using Monterey Garden Insect Spray is its ubiquity in our environment and its safety for human consumption. BT naturally occurs in the soil and is commonly found on brassicas like cabbage and broccoli that we buy from the grocery store. Farmers use BT extensively because it can be applied right up until harvest without any risk to consumers. I’ve personally smoked cannabis that I treated with Monterey Garden Insect Spray and experienced no adverse effects. For anyone dealing with worm infestations, I highly recommend giving BT a try. It’s a natural, safe, and effective solution that won’t harm your plants or your health.
