DIY Thuricide Caterpillar Control: A Gardener’s Guide
Hey fellow gardeners! Are caterpillars turning your precious plants into a buffet? I know the feeling! It’s incredibly frustrating to watch your hard work get devoured. That’s why I’m sharing my go-to method for caterpillar control: Thuricide. It’s a safe and effective biological insecticide that targets caterpillars specifically, leaving beneficial insects unharmed. Let’s dive in!
What is Thuricide and Why Use It?
Thuricide is a brand name for products containing *Bacillus thuringiensis* (Bt), a naturally occurring bacterium found in soil. Different strains of Bt are effective against different pests. For caterpillar control, we’re looking for *Bacillus thuringiensis* var. *kurstaki* (Btk).
Why I love Thuricide:
* It’s safe for beneficial insects: Unlike broad-spectrum insecticides, Thuricide only affects caterpillars that ingest it. Bees, ladybugs, and other helpful critters are safe!
* It’s safe for humans and pets: When used as directed, Thuricide poses minimal risk to humans and pets.
* It’s effective: Thuricide works wonders on a wide range of caterpillars, including cabbage loopers, tomato hornworms, bagworms, and more.
* It’s organic-gardening friendly: Thuricide is often approved for use in organic gardening. Always check the product label for certification.
Materials You’ll Need
Before we get started, gather these supplies:
* Thuricide Concentrate: Make sure it contains *Bacillus thuringiensis* var. *kurstaki* (Btk). I usually buy a concentrate because it’s more economical in the long run.
* Spray Bottle or Garden Sprayer: Choose a sprayer that suits the size of your garden. A small spray bottle is fine for a few plants, but a pump sprayer is better for larger areas.
* Measuring Cup or Spoons: Accurate measurements are crucial for effective application.
* Water: Use clean, non-chlorinated water.
* Gloves: Protect your hands from potential skin irritation.
* Eye Protection: Safety first! Wear safety glasses or goggles to prevent splashes.
* Optional: A small amount of insecticidal soap can be added to the mixture as a “sticker-spreader,” helping the Thuricide adhere to the plant leaves.
Mixing the Thuricide Solution
This is a crucial step! Follow the instructions on your Thuricide product label carefully. The concentration can vary between brands, so don’t assume they’re all the same.
1. Read the Label: Seriously, read it! The label will tell you the correct dilution rate for your specific product. It usually provides instructions for different application methods (e.g., foliar spray, soil drench).
2. Calculate the Amount: Determine how much solution you need based on the size of your garden and the number of plants you’re treating. I usually start with a small batch and mix more if needed.
3. Mix the Solution: In your spray bottle or garden sprayer, add the appropriate amount of Thuricide concentrate to the water. For example, the label might say “1-2 teaspoons per gallon of water.”
4. Add Insecticidal Soap (Optional): If you’re using insecticidal soap, add a small amount (usually 1-2 teaspoons per gallon) to the mixture. This helps the Thuricide stick to the leaves, especially waxy ones.
5. Mix Thoroughly: Close the sprayer and shake well to ensure the Thuricide and water are properly mixed.
Applying the Thuricide Solution
Now for the fun part – getting rid of those pesky caterpillars!
1. Choose the Right Time: Apply Thuricide in the late afternoon or early evening. This gives the solution time to dry before the sun gets too strong, which can degrade the Bt. Avoid spraying on windy days, as the spray can drift to unintended areas. Also, avoid spraying if rain is expected within 24 hours, as it will wash away the Thuricide.
2. Prepare Your Plants: Remove any dead or heavily infested leaves before spraying. This will help the Thuricide reach the caterpillars more effectively.
3. Spray Thoroughly: Spray all parts of the plant, including the tops and undersides of leaves, stems, and flowers. Caterpillars often hide on the undersides of leaves, so don’t miss those spots!
4. Target the Caterpillars: Pay special attention to areas where you’ve seen caterpillars or signs of caterpillar damage (e.g., chewed leaves, droppings).
5. Reapply as Needed: Thuricide is most effective when caterpillars are small and actively feeding. Reapply every 7-10 days, or more frequently if you see new caterpillar activity. Rain can also wash away the Thuricide, so reapply after a heavy rain.
Tips for Success
Here are a few extra tips to help you get the most out of your Thuricide treatment:
* Identify the Caterpillar: While Thuricide is effective against many caterpillars, it’s always a good idea to identify the specific type of caterpillar you’re dealing with. This can help you choose the right product and application method.
* Monitor Your Plants Regularly: Check your plants frequently for signs of caterpillar activity. The sooner you catch an infestation, the easier it will be to control.
* Use a Combination of Methods: Thuricide is a great tool, but it’s not a silver bullet. Consider using it in combination with other caterpillar control methods, such as handpicking, row covers, and attracting beneficial insects.
* Store Thuricide Properly: Store Thuricide in a cool, dry place, away from direct sunlight and extreme temperatures. Follow the storage instructions on the product label.
* Be Patient: Thuricide doesn’t work instantly. It takes a few days for the caterpillars to stop feeding and die. Don’t be discouraged if you don’t see results immediately.
* Consider a Sticker-Spreader: As mentioned earlier, adding a sticker-spreader (like insecticidal soap) can help the Thuricide adhere to the plant leaves, especially waxy ones like cabbage. This is particularly helpful if you live in an area with frequent rain.
* Rotate Insecticides: To prevent caterpillars from developing resistance to Thuricide, consider rotating it with other caterpillar control methods or insecticides with different modes of action.
* Don’t Spray During Bloom: While Thuricide is relatively safe for beneficial insects, it’s best to avoid spraying it on plants that are in bloom, as it could potentially harm pollinators. If you must spray during bloom, do so in the early morning or late evening when pollinators are less active.
* Use Fresh Solution: Mix only the amount of Thuricide solution that you need for each application. Leftover solution can lose its effectiveness over time.
* Consider Systemic Options (Use with Caution): While I generally prefer organic methods, in cases of severe infestation, a systemic insecticide might be necessary. However, use these with extreme caution, as they can harm beneficial insects and the environment. Always follow the label instructions carefully.
* Check pH of Water: The pH of your water can affect the effectiveness of Thuricide. Ideally, the pH should be between 6.0 and 7.0. If your water is too alkaline, you can add a small amount of vinegar to lower the pH.
* Consider a Soil Drench: For some caterpillars, such as cutworms, a soil drench with Thuricide can be effective. This involves pouring the Thuricide solution around the base of the plant, allowing it to soak into the soil.
* Document Your Results: Keep track of your Thuricide applications and their effectiveness. This will help you fine-tune your approach and determine the best timing and frequency for future treatments.
* Dispose of Properly: Dispose of any leftover Thuricide solution and empty containers according to the instructions on the product label. Don’t pour it down the drain or into waterways.
Troubleshooting
What if I don’t see results after a few days?
* Check the expiration date: Thuricide has a shelf life. Make sure your product is still effective.
* Reapply: As mentioned earlier, reapplication is often necessary, especially after rain.
* Increase the concentration: If you’re using a low concentration, try increasing it slightly (but always stay within the recommended range on the label).
* Consider a different product: If Thuricide isn’t working, the caterpillars might be resistant, or you might be dealing with a different type of pest. Consult with your local garden center or extension office for advice.
What if I accidentally spray Thuricide on a beneficial insect?
* Don’t panic! Thuricide is generally safe for beneficial insects. Simply rinse the insect off with water.
What if I get Thuricide on my skin or in my eyes?
* Rinse thoroughly with water. If irritation persists, consult a doctor.

Frequently Asked Questions (FAQ)
What exactly is Thuricide, and how does it work?
Thuricide is a biological insecticide containing *Bacillus thuringiensis* (Bt), a naturally occurring bacterium found in soil. When caterpillars ingest Thuricide, the Bt bacteria produce a protein that paralyzes their digestive system. This prevents them from feeding, and they eventually die from starvation. The great thing about Thuricide is that it’s highly specific to caterpillars and other leaf-eating larvae, meaning it won’t harm beneficial insects like bees, butterflies, and ladybugs, or other wildlife.
Is Thuricide safe for humans, pets, and the environment?
Yes, Thuricide is considered to be very safe for humans, pets, and the environment when used according to the product label instructions. Bt bacteria are naturally occurring and break down quickly in the environment. However, as with any pesticide, it’s always a good idea to take precautions. Wear gloves and eye protection when applying Thuricide, and avoid spraying on windy days to prevent drift. Keep children and pets away from treated areas until the spray has dried. While Thuricide is generally considered safe, some individuals may experience mild skin or eye irritation. If this occurs, rinse thoroughly with water.
How often should I apply Thuricide?
The frequency of application depends on the severity of the caterpillar infestation and the weather conditions. Generally, you should apply Thuricide every 7-14 days, or more frequently if heavy rain washes it off. Monitor your plants regularly for signs of caterpillar activity, such as chewed leaves or droppings. Reapply Thuricide after rain or irrigation to ensure continued protection. For preventative applications, you can apply Thuricide every 2-3 weeks during peak caterpillar season.
What types of caterpillars does Thuricide control?
Thuricide is effective against a wide range of caterpillars, including cabbage loopers, tomato hornworms, armyworms, tent caterpillars, gypsy moth caterpillars, and many others. It’s most effective on young caterpillars, so it’s important to start treatment early in the infestation. Check the product label for a complete list of caterpillars that Thuricide controls.
Can I use Thuricide on edible plants?
Yes, Thuricide is safe to use on edible plants, including fruits, vegetables, and herbs. It has a short pre-harvest interval (PHI), which is the amount of time you need to wait between applying the insecticide and harvesting the crop. Check the product label for the specific PHI for the crop you’re treating. Always wash your produce thoroughly before eating it, even if you’ve used Thuricide.
How should I store Thuricide?
Store Thuricide in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it out of reach of children and pets. Follow the storage instructions on the product label. Properly stored Thuricide can remain effective for several years.
What are the signs that Thuricide is working?
You’ll typically see results within a few days of applying Thuricide. Caterpillars will stop feeding and become sluggish. They may also change color or develop a wilted appearance. Eventually, they will die. It’s important to note that Thuricide doesn’t kill caterpillars instantly. It works by disrupting their digestive system, so it takes a few days for them to die.
Can caterpillars develop resistance to Thuricide?
While it’s possible for caterpillars to develop resistance to Thuricide over time, it’s less likely than with synthetic pesticides. To minimize the risk of resistance, rotate Thuricide with other caterpillar control methods, such as handpicking, using row covers, or introducing natural predators like birds and parasitic wasps. Avoid using Thuricide excessively or unnecessarily.
What if Thuricide doesn’t seem to be working?
If you’re not seeing results after a few days of applying Thuricide, there could be several reasons. First, make sure you’re using the correct concentration of Thuricide and applying it thoroughly to all affected plants. Second, check the weather conditions. Thuricide is most effective when applied in dry weather. Rain can wash it off, reducing its effectiveness. Third, make sure you’re targeting the right type of caterpillar. Thuricide is most effective on young caterpillars. If you’re dealing with older, more mature caterpillars, you may need to use a higher concentration of Thuricide or try a different control method. Finally, consider the possibility that the caterpillars have developed resistance to Thuricide. If this is the case, you’ll need to rotate to a different control method.
Where can I buy Thuricide?
Thuricide is widely available at garden centers, nurseries, hardware stores, and online retailers. Look for products that contain *Bacillus thuringiensis* (Bt) as the active ingredient. There are several different strains of Bt, so choose one that is effective against the specific type of caterpillars you’re dealing with.
