How to Get Rid of Caterpillars on Dew Plant

Dew plants are a beautiful addition to any garden or landscape. However, they are also a favorite food source for caterpillars. Caterpillars can quickly decimate a dew plant, leaving it stripped of leaves and unsightly. If you’re dealing with caterpillars on your dew plant, don’t worry, there are several effective ways to get rid of them.

1. Handpicking

One of the most effective ways to get rid of caterpillars is by handpicking them off the plant. This method is best used for small infestations. Simply inspect your dew plant regularly and remove any caterpillars you find. Be sure to wear gloves to protect your hands from any spines or other irritants on the caterpillar’s body.

2. Natural Predators

Another way to get rid of caterpillars is by introducing natural predators into your garden or landscape. Birds, ladybugs, and praying mantises are all natural predators of caterpillars. You can attract these predators to your garden by planting flowers and other plants that they like.

3. Insecticides

If handpicking and natural predators aren’t effective, you can use insecticides to get rid of caterpillars. There are several types of insecticides available that are safe for use on dew plants. Be sure to read the label carefully and follow the instructions for use.

4. Neem Oil

Neem oil is another effective way to control caterpillars on dew plants. It’s a natural insecticide that’s safe for use on plants and won’t harm beneficial insects like bees and ladybugs. Simply mix neem oil with water according to the package instructions and spray it directly onto your dew plant.

5. Bacillus Thuringiensis

Bacillus thuringiensis, or Bt, is a natural bacteria that’s effective against caterpillars. It’s safe for use on plants and won’t harm beneficial insects like bees and ladybugs. Simply mix Bt with water according to the package instructions and spray it directly onto your dew plant.

6. Companion Planting

Companion planting is another way to control caterpillars on dew plants. By planting certain herbs and flowers near your dew plant, you can repel caterpillars and other pests. Some good companion plants for dew plants include marigolds, sage, and thyme.
