How to treat pests on bay trees?

Bay trees are a stylish, aromatic addition to many UK gardens and a beloved choice for gifts. But even these hardy evergreens are vulnerable to pest infestations. If your bay tree is looking under the weather, it might be down to some uninvited guests. This step-by-step guide will help you spot the signs, treat the issue, and protect your tree naturally and sustainably.

Our 5 step check list to treat bay tree pests

Step 1: Identify the pest

The most common pests that affect bay trees in the UK include:

  • Bay suckers: tiny, brownish insects that feed on leaf sap, causing curling and distortion.
  • Caterpillars: these munch through leaves quickly and can cause major defoliation.
  • Scale insects: small, oval-shaped bugs that attach to leaves and stems, often leaving a waxy or sticky residue.

Look out for curled leaves, spots or stickiness. All signs your bay tree may be under attack.

Step 2: Try natural remedies first

Natural methods are usually best for treating pests on bay trees. Try the following:

  • Neem oil: a botanical insecticide that disrupts pests' life cycles without harming beneficial insects.
  • Insecticidal soap: safe for most garden plants, it suffocates soft-bodied insects on contact.

Apply in the early morning or evening and avoid spraying in direct sun to protect the leaves.

Step 3: Remove infested leaves

If you spot leaves that are heavily infested or damaged, remove them to prevent further spread. Dispose of them in your garden waste bin (not your compost) to stop pests reappearing.

Step 4: Use chemical pesticides carefully

If the infestation persists, you may need to use a chemical pesticide – but choose carefully. Follow the manufacturer’s instructions and wear gloves. Always opt for bee-friendly products where possible, and never spray in windy weather or on flowering plants.

Step 5: Keep your tree in good health

Prevention is the best protection. Ensure your bay tree has:

  • Well-draining soil and regular watering
  • Plenty of sunlight
  • Seasonal pruning to improve airflow
  • Feeding during the growing season to boost resilience
