What Kind of Pest is Killing Your Grass?

Having a lawn that is consistently green and lush might be a concern, especially when pests can lurk beneath the greenery.

There are certain things to be wary of when looking out for pests. Some of the things to look out for when your lawn could be being attacked by pests are wilting grass, decaying or dead patches of grass, holes that lead into the ground, and sightings of insects.

There are certain pests that may be involved with destroying your yard.


There are a variety of different types of larvae in the grub and beetle species that are different in size and tint. Most of the grubs are shaped in a letter C and are less than an inch of sighs. Grubs can be found beneath the Earth’s soil and maybe the reason why your grass is dying since they feast on the roots beneath lawns.

Chinch Bugs

These bugs are the smallest in size as they are only a quarter of an inch long. They are black and white in color with white-gray wings with triangular patches on them. These pests are notorious for sucking the moisture out of grass blades. They deposit warfarin that prevents your grass from taking in water.

If your lawn turns from purple or red to yellow then brown then these pests may be lurking in your lawn.

The best way to get rid of them is by using Diatomaceous Earth. There are plenty of options out there for Diatomaceous Earth, even food-grade ones that are safe for the environment and other more helpful bugs like lizards.


When it comes to Armyworms, they are the colors of brown, black, green, or yellow and are about an inch and a half in size with stripes that align horizontally.

Armyworms, like grubs, feed on grass but instead of being beneath the grow they lurk on top of it.

If your grass is brown in color or looks like it hasn’t been watered even though it has been, then armyworms may be what is killing your lawn.

Mammalians That Dig

It may not seem likely but mammals could be the reason your lawn is dying. Mammals such as chipmunks, gophers, and other mammals that burrow beneath the grown can damage your lawn.

The best way to handle situations that involve mammals is to call a professional to identify if there is a mammal at play and to figure out if there is a proper solution to handling the mammal.
