Pests & plant health

Recognise and support helpful garden insects

Observe before removing insects.

When to do it

Whenever inspecting flowers, aphids or other small insects.

What you need

  • Hand lens or close photograph
  • Local identification resource

How to do it

  1. Observe before removing insects. Ladybird and lacewing larvae can look very different from their adults, and hoverfly larvae often occur among aphids.
  2. Use a reliable local identification source rather than colour alone; not every similar-looking beetle has the same diet.
  3. Keep a variety of suitable flowering plants and some undisturbed habitat nearby while keeping crop access clear.
  4. Avoid unnecessary broad-spectrum treatments. Recheck whether natural predators are holding a small pest population steady.

What success looks like

  • Helpful insects remain while crop damage is monitored.

Watch out for

  • Removing every larva because it looks unfamiliar.
  • Assuming predators will solve a severe infestation immediately.
