How to Protect Your Fruit Trees from Fruit Fly: A Complete Guide

Fruit fly is one of the most destructive pests facing Australian gardeners. A single infestation can wipe out an entire season's harvest — mangoes, stone fruit, citrus, and more. The good news? With the right protection in place, you can keep fruit fly out entirely, without chemicals or traps.

Why Fruit Fly Is Such a Problem in Australia

Australia is home to several species of fruit fly, including the Queensland fruit fly (Bactrocera tryoni) and the Mediterranean fruit fly (Ceratitis capitata). Both lay eggs inside ripening fruit, and the larvae destroy the flesh from the inside out — often before you even notice the damage.

Warm, humid conditions across much of Australia make fruit fly pressure intense from spring through autumn. If you grow stone fruit, citrus, figs, or tropical varieties, you're almost certainly dealing with this pest every season.

Common Fruit Fly Control Methods — and Their Limits

Most gardeners try one or more of these approaches before discovering netting:

• Baiting and traps: Attract and kill adult flies, but don't prevent eggs already laid in fruit.
• Sprays and pesticides: Require repeated applications, have withholding periods, and can affect beneficial insects.
• Paper or organza bags: Labour-intensive to apply to every piece of fruit, and impractical for large trees.
• Exclusion netting: The only method that physically prevents fruit fly from reaching your fruit — no chemicals, no ongoing cost.

How Fruit Tree Netting Works

Exclusion netting creates a physical barrier around your tree, preventing fruit fly (and birds) from accessing the fruit at all. The key is using netting with a fine enough mesh to block fruit fly while still allowing sufficient airflow.

flipNet® fruit tree netting is engineered specifically for this purpose. It blocks fruit fly and birds while remaining breathable and UV-stabilised for Australian conditions.

Step-by-Step: Protecting Your Fruit Trees from Fruit Fly

1. Choose the right size net: Measure your tree's canopy width and height, each flipNets suggest ideal tree sizes.  
2. Drape and secure: Pull the net over the tree and secure it at the base to prevent pests from entering underneath. Pegging to the ground works or use the large band that comes with every flipNet..
3. Leave it on through the season: Keep the net in place from when fruit begins to form until harvest is complete.

Tips for Maximum Effectiveness

• Install netting as soon as blossom has fallen and fruit has just set  — to allow pollinators access to your blossom
• Store nets off-season in a cool, dry place to extend their lifespan.
