How to Breed Ladybugs to Protect Plants from Pests

My fennel and artichokes are currently facing a bit of a challenge with aphids. Initially, I considered using my homemade bug spray, a blend of garlic and soap, to tackle the issue. However, I have to be mindful since the pollen from the fennel and artichokes is currently attracting a lot of honey bees.


Any treatment I use against the aphids, particularly those containing detergents, could also harm the bees. Moreover, the recent rainy weather means any spray I apply doesn’t stay on long enough to be effective.

So, for now, the aphids are feasting unchecked on my plants. But this situation might not last much longer, as I’ve just observed a promising development.

Enter the ladybugs, turning my aphid issue into an opportunity for them. Ladybugs are fascinating creatures. Despite their charming appearance and seemingly gentle nature, they are surprisingly effective in such situations.

Understanding Ladybug Species

They’re likely to gather reinforcements from the surrounding area to help with my aphid problem. Ladybug larvae can consume around 50 aphids daily. A single ladybug can lay up to 1500 eggs in her lifetime, placing them on the undersides of leaves.

These eggs hatch in two to five days, and the larvae live for about three weeks. They resemble miniature crocodiles adorned with orange stripes.

After this period, they enter the pupation stage. It takes approximately four days for them to transform into adults. Doing the math, one adult ladybug can eliminate around 5000 aphids in its lifetime.

Just this week, we had the opportunity to watch a ladybug emerge from its pupal stage, which was quite a thrilling experience for us.

Here’s what you’ll need for breeding Ladybugs

  1. A suitable enclosure, like a mesh cage or terrarium, to provide a safe breeding environment.
  2. A steady supply of food, primarily aphids or other small insects, suitable for both larvae and adult ladybugs.
  3. Leafy plants or artificial substrates to mimic their natural habitat and provide places for egg laying.
  4. Adequate moisture through regular misting to maintain humidity without making the environment too wet.
  5. Controlled temperature conditions, ideally between 20°C to 27°C (68°F to 80°F), to facilitate breeding and development.
  6. A light source to mimic natural day and night cycles, crucial for the ladybugs’ lifecycle.
  7. A supply of water, preferably in the form of a damp sponge or shallow water dish, to prevent drowning.
  8. Regular cleaning tools to maintain hygiene and remove waste from the breeding enclosure.
  9. Magnifying glass or similar tool for closely monitoring eggs, larvae, and pupae.

Step-by-Step Guide to Breeding Ladybugs

Step 1: Setting Up the Breeding Environment

  • Select an Enclosure: Use a terrarium, large jar, or a mesh enclosure to provide a safe and controlled environment.
  • Create a Habitat: Line the enclosure with natural materials like leaves, sticks, and a few stones to mimic their natural habitat.

Step 2: Collecting Ladybugs

  • Gently capture a few ladybugs from your garden or purchase them from a reliable supplier. A soft brush or a piece of paper can be useful for this.

Step 3: Preparing the Habitat

  • Place aphid-infested leaves inside the bug hotel. These will serve as a food source for the ladybugs.
  • Add some leafy plants or artificial substrates to provide natural habitats and spaces for egg laying.

Step 4: Providing Moisture

  • Include a few cotton balls soaked in water in the enclosure. This will help maintain the necessary humidity.

Step 5: Introducing Ladybugs to the Enclosure

  • Once everything is set up, place the ladybugs inside the bug hotel. Do this in the evening or early morning when they are less active.
  • Monitor the environment, ensuring it remains suitable for the ladybugs.

Step 6: Observation and Maintenance

  • Monitor the environment daily, ensuring the temperature is between 20°C to 27°C and the habitat stays humid but not wet.
  • Regularly check on the ladybugs, the condition of the leaves, and the moisture level.

Step 7: Releasing the Ladybugs

  • After noticing an increase in their numbers and the emergence of new ladybugs, prepare to release them into the garden.
  • Choose a suitable time, preferably in the early morning or late evening, for the release.

Step 8: Ongoing Observation

  • Monitor the Garden: Observe the ladybugs in your garden, noting their impact on aphid populations and plant health.

Important Tips

  1. Avoid Chemicals: Ensure your garden is free from pesticides, which can harm ladybugs.
  2. Gentle Handling: Be delicate when handling ladybugs and their habitat.
  3. Educational Opportunity: Use this as a learning opportunity, especially if involving children in the process.
