Trabe Bacillus Thuringiensis 40gr · Organic Caterpillar Killer

Trabe Bacillus Thuringiensis 40gr is the definitive biological weapon to save your crop from one of the most voracious and destructive pests: the caterpillar. This specific bioinsecticide acts selectively to eliminate larvae without compromising the quality of your flowers or the health of your environment, ensuring that your hard work doesn't end up as worm food.

There is a lot of noise and misinformation regarding pest control in cultivation. You often hear that "organic doesn't kill" or that you need strong chemicals to stop a plague of worms. This leads many growers to panic and use toxic products that remain in the flower, or worse, to trust home remedies that simply tickle the bugs while they devour the crop.

The result of this confusion is tragic: buds full of excrement, the appearance of botrytis (bud rot) due to caterpillar bites, and a harvest that tastes like chemical products. Thinking that a biological product is "weak" is a mistake that can cost you the entire season. If you don't act fast and with the right tool, caterpillars can decimate a plant in a matter of nights.

The solution is science applied to nature. Trabe Bacillus Thuringiensis is not a "repellent"; it is a lethal bacterium for caterpillars that works with surgical precision. It is the industry standard for a reason: it works. This description is your honest guide to understanding how to use it, what to expect, and why it is the staple of any professional grower's medicine cabinet.

Typical myths about biological insecticides

• Myth: "It kills all bugs, including the good ones." Reality: It is highly selective; it only affects Lepidoptera larvae (caterpillars) and is harmless to bees or ladybugs.
• Myth: "It takes too long to kill them." Reality: Although the caterpillar may take 2-5 days to die, it stops feeding (and damaging your plant) just a few hours after ingesting the product.
• Myth: "You cannot use it in flowering." Reality: Being 100% organic and biodegradable, it has a very short safety period and is one of the safest options for the flowering stage.
• Myth: "It works by contact like other poisons." Reality: It works by ingestion. The caterpillar must eat the leaf sprayed with the product for it to take effect.

What this product really does (and what it doesn't)

Trabe Bacillus Thuringiensis contains spores of the bacterium Bacillus thuringiensis var. kurstaki. When a caterpillar eats a leaf treated with this powder, the bacteria release toxins that are activated by the alkaline pH of the insect's gut. This destroys their digestive system. The immediate effect is that the caterpillar feels "full" or sick and stops biting your plants almost instantly. It doesn't die on the spot, but it stops being a threat immediately.

It is important to understand that this product is not an egg-killer (ovicide) nor does it kill adult moths. Its function is to kill the larvae, which are the ones that eat the green material. It also won't work on mites or aphids; for those, you need other types of insecticides cannabis. Its specialization is its greatest strength.

Advantages and benefits when used properly

• Immediate protection: The damage stops hours after application, preserving the integrity of your buds.
• Zero toxicity: You can use it without fear of poisoning yourself, your pets, or the local fauna.
• Prevents Botrytis: By eliminating caterpillars, you eliminate their excrement and bites, which are the main cause of fungal rot in the final phase.
• Compatible with other products: You can alternate it with other cannabis fertilizers or preventatives without chemical reactions.
• No residual flavor: Unlike chemical insecticides, it does not alter the flavor or aroma of your flowers if the minimum safety periods are respected.

Tips to choose well according to your expectations

If you are looking for a product that drops the bug the second it touches it, this is not for you (and honestly, you shouldn't want that on your smoking material). This product is for the smart grower who understands biological cycles. If you have a massive plague with large caterpillars, you will need to apply it thoroughly and perhaps remove the largest ones by hand.

• If you expect prevention: Apply it every 10-15 days from the beginning of summer or when you see the first butterflies fluttering around.
• If you expect cure: Apply a higher dose and repeat every 3-5 days until the plague stops.
• Crucial tip: Degrades with sunlight. Always apply at dusk/nightfall and ensure the pH of the water is around 6.0-7.0 for maximum effectiveness.

Frequently Asked Questions

Does it really work on big caterpillars?

Yes, but it is more effective on small larvae (early stages). Large caterpillars eat more and may require a higher dose or more frequent applications to ingest enough toxin. It is always better to catch them early.

Can I use it just before harvest?

Technically, it has a very short safety period (0-3 days depending on regulations), but we always recommend stopping any foliar application about 10-15 days before Harvesting and Drying Marijuana to avoid excess moisture in the buds.

What is the difference compared to Neem Oil?

Neem is a systemic repellent and prevents molting, working on many pests but slowly. Bacillus is a specific stomach poison for caterpillars. They are a great combo: Neem to repel, Bacillus to kill if they enter.

Personal Experience of Pevgrow’s CEO (Alan)

I've heard people say "I sprayed Bacillus and the caterpillar is still there." And I always tell them: look closely, is it moving? Is it eating? Because usually, the poor thing is just there, paralyzed, waiting to die. In my experience, there is nothing that gives me more peace of mind in outdoor crops than Bacillus. I've seen entire harvests thrown away because of a single caterpillar that rotted the main cola from the inside.

My advice is not to wait to see the holes in the leaves. In my garden, Trabe Bacillus Thuringiensis is mandatory once a week as soon as the flowering starts. It's cheap, it's easy to mix, and it saves you from the drama of finding mold when you're manicuring. Don't play it safe with caterpillars, they are the most destructive pest.
