Understanding Leatherjackets and Their Effects
Crane fly larvae, or larval pests, reside in the soil and consume grassroots and decomposing plant matter. Activity peaks in mild weather, often resulting in loose turf and increased surface vulnerability. On grounds in use, this can interfere with play and increase upkeep requirements.
Spotting the Signs Early
Feeding birds, unusual thinning, and irregular patches often signal larval feeding. Cutting inspection areas allows for population assessment. Consistent observation in late winter and early spring enables prompt treatment decisions.
Turf Care During Key Seasons
Leatherjackets stay below ground during winter but will continue feeding if conditions permit. Neglected populations cause slow turf recovery as temperatures rise. Knowing their behaviour allows grounds teams to plan maintenance that anticipates seasonal stress.
Cultural Approaches to Control
Many turf professionals rely on cultural practices. Aerating the ground promotes deeper root growth and more resilient swards. Adjusting mowing height minimises turf stress. Rolling in damp conditions can expose leatherjackets, making them easier for natural predators to reach. These measures build resistance, though they don’t eradicate infestations.
Using Living Organisms to Manage Leatherjackets
Microscopic nematodes are a biological solution that destroy crane fly larvae underground. Their effectiveness is linked to soil temperature, moisture, and correct application—usually in late summer. Used properly, nematodes can significantly reduce larval numbers without chemical input.
When to Use Chemicals
On demanding surfaces like playing fields, chemical products may be justified. Only licensed products should be used, and always in line with regulation and guidance. Combining targeted chemical use with other strategies often leads to stable turf conditions.
Long-Term Larvae Management
Future-proofing turf involves improving drainage, building root systems, and ensuring adequate nutrient levels. After crane fly emergence in late summer, checking the grounds helps forecast the next season’s risk. Proactive measures cut future impact over time.
FAQs About Leatherjackets and Control
- When are larvae most active?
Activity is typically observed in autumn and spring. - How do I check for infestation?
Cut small turf squares and count larvae beneath to determine infestation levels. - Are nematodes effective in cold soil?
No, they require certain temperatures and moisture levels to work properly. - Should I alter mowing height?
Yes, longer grass during feeding seasons can support recovery. - What causes birds to peck at turf?
Birds are usually attracted to larvae near the surface. This is often an early indication of a problem.

Key Points
Managing crane fly larvae requires regular attention, timely actions, and a balanced approach. Grounds treated with this methodology are more likely to stay usable across all seasons.
