A recent influx of videos across social media has brought leather jackets to many gardeners' attention. The larvae of crane flies, known as leather jackets, can be damaging to lawns and are worth dealing with as soon as possible to avoid further damage.
If you're keeping on top of your lawn care but find your lawn is yellow still, leather jackets could be the problem. These pests feed on grass roots, causing dead and discolored patches. That's why it's important to deal with this pest problem to ensure your lawn doesn't become further damaged.
We've asked experts about how to get rid of leather jackets and what kind of damage they cause.
What are leather jackets?
'The larvae of crane flies are known as leather jackets. Their bodies are long, grey-brown and usually divided into segments. They are found under soil surfaces, especially on lawns or turf,' says Allan Bossel, pest control expert.
While leather jackets may not look intimidating, experts note they can cause quite a bit of damage to lawns.
'Your lawn may get patches of brown or yellow discoloration as a result of their feeding on the roots and stems of the grass. These patches might not look like much at first, but if they are not addressed they can spread quickly and become unattractive blotches in otherwise gorgeous, green lawns,' says Allan.
The way leather jackets feed on lawn is what causes the damage. Failing to deal with the problem could cause further damage and kill more of your grass. Luckily, experts have told us how to get rid of leather jackets and prevent further harm to your lawn.
How to get rid of leather jackets
The first thing you should do if you think you have a leather jacket infestation is put precautions in place to prevent more appearing.
'Leather jackets thrive in moist soils, so you can deter them by avoiding overwatering,' says Allan.
It's best to avoid lawn watering mistakes so that you don't water your lawn for too long. This will help deter crane flies by creating an uninhabitable environment.
'Regular aeration of your lawn can also disrupt their lifecycle and make the environment less hospitable for them,' Allan adds.
To get rid of the leather jackets already in your lawn, there are a few things you can do. 'While pesticides are an option, a more eco-friendly approach would be to use nematodes, microscopic worms that are natural predators of leather jackets,' says Allan.
Allan suggests applying nematodes to your lawn during cooler months when leather jackets are in the larval stage. 'This can effectively eliminate them,' he says.
Nematodes are widely available online, like these nematodes from Walmart or this leather jacket nematode treatment from Amazon.

How do you revive a leather jackets-damaged lawn
Although possible, reviving a lawn from leather jacket damage can take some time.
'The dead grass might need to be removed before you reseed or returf the affected areas,' says Allan Bossel, pest control expert. 'Patience is key. The new grass needs time to grow and it might take several weeks or even months before your lawn regains its original beauty,' he adds.
Keeping on top of lawn care can help nurture your lawn back to health. 'Be sure to monitor your lawn for signs of leather jacket presence during this time to prevent a repeat of the damage,' says Allan.
If you notice damage from leather jackets, it's a good idea to prevent and remove them to stop your lawn becoming damaged any further. Find out more about protecting your lawn from pests by researching when to apply grub control.
