🐛 Leatherjacket treatment season is here! 🌱
Now is the optimum time to consider leatherjacket control, with Syngenta identifying around 20th October as the key target date for autumn treatment.
Leatherjackets are the soil-dwelling larvae of daddy longlegs flies. They feed on grass roots and can cause significant lawn damage, leaving areas thinning, yellowing and eventually dying back. Birds and badgers digging for the grubs can cause further disruption.
Following this summer’s prolonged drought, many lawns are already under stress, making it even more important to protect turf health and support recovery.
At Lawn Feeder, we can assess your lawn for signs of leatherjacket activity and advise on suitable treatment options to help protect your investment.
