Natural predators

No matter what the pest, there’s a natural predator. For example:

  • Birds eat slugs, snails, grubs, wireworms, caterpillars and insects
  • Hedgehogs eat slugs and snails, beetles and insects
  • Frogs and Toads eat slugs, snails and various insects
  • Ladybirds and lacewings eat aphids such as blackfly and whitefly

Hand picking

While removing areas of infestation by hand is time-consuming and intensive, it can be beneficial to the rest of the plot.


Biological control

Encarsia, a parasitic wasp is useful for removing Whitefly. They work by attacking and paralysing the nymph of the Whitefly. With less of them around, your vulnerable plants are far better protected.


Companion planting

Deterrents and Barriers

Placing plastic bottles and straw around the base of plants can also deter most pests.
