Codling moth is one of the most damaging orchard pests in Greece, tunnelling through apples, pears, and quinces before you even notice the problem. The video above from Gardening Australia walks through several practical management methods; the steps below give you a clear, season-by-season action plan suited to homes, villas, and hotel grounds across the Greek climate. Act early — once the larvae are inside the fruit, the damage is already done.
What Is Codling Moth and Why Is It So Destructive?
Codling moth (Cydia pomonella) is a small, grey-brown moth whose caterpillars bore straight into developing fruit to feed on the core. A single female can lay up to 70 eggs per season, and in warm Mediterranean conditions like Greece there can be two or even three generations per year — meaning infestations build up fast if ignored.
The tell-tale signs are small entry holes ringed with brown frass (excrement) on the fruit skin, premature fruit drop, and the pink-white grub you find when you cut open the apple. By the time the grub is visible, the larva has already destroyed the fruit's core and is ready to pupate in bark crevices, starting the cycle again.
Timing Your Control: The Greek Growing Season
In Greece, codling moth adults begin flying when apple blossom petals fall — typically late March to April in southern regions and May in the north. The key window for action is those first two to three weeks after petal fall, when eggs are being laid and young larvae are still on the fruit surface before they burrow in.
A second flight occurs in mid-summer (June–July), and sometimes a partial third generation appears in late August. Monitoring with pheromone traps lets you track exactly when moths are active so you can time sprays and other interventions with precision rather than guessing.
5 Steps to Control Codling Moth
- 1
Hang Pheromone Traps Before Blossom
Place at least one pheromone sticky trap per tree (or one per two trees for small varieties) in the canopy before buds open. The traps attract and capture male moths, dramatically cutting mating success. Check the trap weekly and record catch numbers — a sudden spike tells you egg-laying has begun and it is time to apply other controls. Replace the lure every four to six weeks.
- 2
Apply a Targeted Spray at Petal Fall
Time your first spray for seven to ten days after 90% of petals have dropped, when newly hatched larvae are still on the fruit surface. Effective options include kaolin clay (a fine mineral coating that deters egg-laying and larval entry), spinosad-based insecticides (certified for organic use), or codling-moth-specific granulovirus (CpGV) products. Repeat every ten to fourteen days while the trap count remains high, always following label rates.

Band Tree Trunks to Trap Pupating Larvae
In late spring, wrap a 10–15 cm band of corrugated cardboard or burlap around the main trunk and scaffold branches at roughly knee height. Larvae descend the trunk to pupate in bark crevices and instead shelter inside the band. Check and destroy the bands — burn or drop them in hot soapy water — every two to three weeks. This alone can remove a significant proportion of the next generation before it ever flies.
- 4
Thin Fruit and Remove Drops Immediately
Thin developing apples and pears to one fruit per cluster in early June; this removes 'entry points' where two fruits touch, which the larvae exploit to bore in unseen. More importantly, pick up and destroy every fallen fruit within 24–48 hours — infested drops contain live larvae that will pupate in the soil or bark and re-emerge as adults. Bag the drops in a sealed bin liner rather than composting them.

Clean Up Bark and Mulch in Winter
After leaf fall, scrape loose and rough bark from the trunk and main branches with a stiff brush and collect the debris — this destroys overwintering pupae sheltering beneath it. Apply a fresh layer of coarse wood-chip mulch around the drip line to disrupt ground-level pupation sites. A winter dormant oil spray at this stage also smothers any remaining eggs or pupae on the bark, reducing the starting population for the following spring.

FAQ
- Can codling moth damage trees in a Greek garden that has no other apple trees nearby?
- Yes. Adult moths are strong fliers and can travel several hundred metres, so even an isolated tree can be colonised from a neighbour's orchard or wild fruit trees. Pheromone traps and trunk banding are still worthwhile even if you only have one or two trees.
- Is it safe to eat fruit that has codling moth damage?
- The larva itself is not toxic, and the unaffected flesh around the tunnel is safe to eat once you cut away the damaged core. However, the entry wound often allows secondary fungal or bacterial rot to develop quickly, so damaged fruit should be processed or eaten promptly and never stored with healthy fruit.
- How many times a year do I need to treat for codling moth in Greece?
- In most parts of Greece you should plan for at least two treatment windows — after petal fall in spring and again in mid-summer when the second flight peaks. In hotter southern regions a third, lighter intervention may be needed in late August. Pheromone traps tell you exactly when each flight is peaking so you do not waste product spraying outside the active period.
