Different Types of Natural Predators Available and How to use Them

There are varieties of natural predators that you can introduce to your farm. Below are the common ones that can be used in South Africa.

Ladybug

One of the most common natural predators used for pest control in South Africa is the ladybug. Ladybugs feed on aphids and other soft-bodied insects, and they can easily be introduced into your garden by simply releasing them into the garden. The ladybug is an ideal natural predator to use because it is harmless to other beneficial insects, such as honeybees and butterflies.

Ladybugs can be used in several ways to help protect plants from damage caused by pests.

  1. Purchase ladybugs from a garden center or online supplier and release them into your garden or farm. Ladybugs will naturally seek out areas where they can find food, so releasing them near your crops is a good idea.
  2. Introduce natural predators into your garden or farm. Ladybugs feed on aphids and other soft-bodied pests, but other beneficial insects, such as lacewings, ground beetles, and parasitic wasps, can also help to keep pest populations under control.
  3. Plant companion flowers near your crops. Ladybugs are attracted to certain types of flowers, so planting them near your crops can help to draw them in.
  4. Keep your garden or farm free of weeds and debris. Ladybugs need somewhere to hide during the day, so keeping your garden or farm free of weeds and debris will help to provide them with the shelter they need.
  5. Provide water and food sources. Ladybugs do not need large sources of water, but providing them with shallow dishes of water and small piles of ripe fruit or vegetables can help to attract them to your garden or farm.
  6. Introduce ladybugs into greenhouses. Ladybugs can help to control pest populations in greenhouses, which can be difficult to manage using traditional methods.

Lacewing

Another natural predator used for pest control in South Africa is the lacewing. Lacewings, which have long, delicate wings, feed on aphids, mites, and other small insects. These beneficial insects can be purchased from garden centers or can be released directly into the garden.
