How to spot Leatherjackets & Chafer Grubs

Do You Have Leatherjackets or Chafer Grubs in Your Lawn?

Both of these lawn pests can do serious damage – and often go unnoticed until it’s too late. Here’s how to spot the signs:

Visible Signs of Damage

• Patchy, brown or thinning grass despite watering
• Spongy or loose turf that lifts easily – like a carpet
• Birds, badgers or foxes digging at your lawn (they’re hunting for the grubs)
• Wilting grass even when soil is damp

What Are They?

• Leatherjackets are the larvae of crane flies (daddy long legs). They feed on grass roots and can destroy large areas of lawn.
• Chafer grubs are the larvae of chafer beetles. They’re white, C-shaped, and also feast on roots, leading to turf damage and dieback.

Try the Soak Test

Not sure if you have them? Here’s a simple DIY test:

1. Soak a patch of lawn with water in the evening.
2. Cover it overnight with a black bin liner or piece of carpet.
3. Lift it in the morning – if grubs are present, they’ll rise to the surface.
