Caterpillars can be a real problem for yerba mate plants, especially during the growing season. These pests eat away at the leaves and can cause serious damage to your plant. Fortunately, there are several effective ways to get rid of caterpillars on your yerba mate plant.
Before you begin treating your yerba mate plant for caterpillars, it’s important to identify the species of caterpillar you’re dealing with. This will help you determine the best course of action. Some common caterpillar species that attack yerba mate plants include:
One of the easiest ways to get rid of caterpillars on your yerba mate plant is to simply handpick them off. This may be time-consuming, but it’s an effective method for small infestations. You can wear gloves and use a pair of scissors or pruning shears to remove the caterpillars.
Neem oil is a natural insecticide that can be used to get rid of caterpillars on your yerba mate plant. It works by disrupting the insect’s hormonal balance, which eventually kills them. To use neem oil, mix it according to the package directions and spray it onto the affected parts of your plant.
