Grub Control in Seattle, WA: Why Your Lawn Gets Destroyed (and How to Fix It)

Have you noticed your lawn getting torn up? It can look like animals are digging everywhere overnight.

That is usually caused by grubs.

In Seattle, this is common. Your lawn may feel soft, lift up like carpet, or get damaged quickly. Here is how to deal with it.

What Are Grubs?

Grubs are baby beetles that live in the soil. They:

  • Eat grass roots
  • Kill sections of your lawn
  • Attract raccoons and birds that dig up your yard

If you do nothing, your lawn will keep getting worse.

Types of Grub Control

There are two main options:

1. Preventative Grub Control (Best Option)

  • Stops grubs before they hatch
  • Common product: GrubEx
  • Works for several months
  • Safer than older chemicals

Best choice if you want to avoid damage.

2. Curative Grub Control (After Damage)

  • Kills grubs that are already in your lawn
  • Common products: Sevin (carbaryl), Dylox
  • Works fast

Use this if your lawn is already damaged.

When to Apply in Seattle

Preventative:

  • Late May to July (best time)
  • Apply before eggs hatch

Curative:

  • August to October
  • When grubs are active

If you wait until fall to prevent, it is too late.

Using Grub Control with Seeding

Before seeding:

  • Safe to apply
  • Helps protect new grass

After seeding:

Preventative treatment works well with new grass.
