Leatherjackets are one of the most common lawn problems. They are the larvae stage of the Common Crane Fly or “Daddy Long Legs”. These larvae can cause considerable damage to lawns, turning them into dead and barren landscapes. Leatherjacket-infested lawns attract all manner of birds, who eat the larvae as well as the adult insects.


How Do Leatherjackets Get Into Lawns?


The lifecycle of a leatherjacket begins when eggs are laid in a lawn around September. The eggs hatch throughout October. Wet and warm weather during October sees the larvae staying near the soil surface, feeding on the top of the root system. Through the winter months, very little evidence of damage is visible, as the larvae are very small in size at this point. As the larvae continue to grow, the damage they inflict becomes more extensive.


How Long Do Leatherjackets Stay In A Lawn?


Leatherjackets will stay in a lawn until they become adult Crane Flies in July and August.


Signs of a Leatherjacket Infestation


The effects of a leatherjacket infestation are most noticeable during dry spring weather when the turf starts to die off due to an inadequate root mass which is incapable of providing water and nutrients to the plant.


There are several signs that indicate the presence of leather jackets. These include the observation of a large number of adult Crane Flies during the months of July and August. The appearance of Rooks, Crows and Starlings feeding on the lawn is another sign of infestation. You may notice bare patches on the grass, as well as yellow patches in early spring, which can also indicate the presence of leatherjackets.

Q) What Does Lawn 3 Do?


Lawn 3 specialises in the treatment and restoration of your lawn. We offer several types of lawn treatment which are detailed below.

Q) What’s the Difference between Lawn 3 Products and Garden Centre Products?


Garden centre products are diluted so that no professional qualifications are required to buy or apply them. But this also means that they can be less effective when applied to your lawn. As well, many of these products are a mixture of lawn food, moss killer, greener and weed killer, which also compromises their effectiveness.

As well, garden centre products are designed to give a flush of growth so that you see visible results sooner. Unfortunately, much of the solution is too strong to be absorbed by your lawn and simply washes away. All of the operators at Lawn 3 are NPTC qualified, able to purchase and apply professional-strength fertilisers and weed killers to your lawn.

All of the products Lawn 3 applies are slow release, which allows a carefully regulated release of nutrients into the soil for a lawn that not only looks healthy on the surface, but really is healthy all the way from root to top.

Our Happy Clients

"Stephen Monk Lawn 3 has been looking after our lawn for nearly three years , and we are very pleased with the personal service he provides and the results achieved to date. Previously over a period of some last seven years we had a similar service from two other lawn care providers. In each case we decided, after a reasonable period, that they were not providing the service we had expected. We found Lawn 3 by an internet search, and were impressed by the personal service referred to in the website testimonials Our lawn has suffered for many years with red thread. We are currently nearly free of this thanks to Stephen. He takes considerable pride in his work and makes you feel your lawn is important to him. He is extremely approachable whilst providing a professional caring service often giving simple self help tips to improve the lawn. Thanks Stephen"

Graham Motteram - Turnditch Derbyshire,

"Dear Steve, Lawn3 reseeded our lawn in the spring and we are very pleased with the result. Rather than a lawn filled with dandelions and Mind Your Own business we now have a beautiful thick green lawn - too nice to walk on! Steve is always helpful, keeps to his appointment times and has gone out of his way to give us extra advice. For anyone wondering whether to go for laying turf or seeding a lawn I would definitely recommend the latter. Our garden is shaded by a large tree so Steve has seeded with a shade tolerant grass seed - we are delighted. Thanks Steve"
