Tropical Sod Webworms – A Threat to Our Lawns?

Introduction

Tropical sod webworms can wreak havoc on your lawn during the humid, tropical or sub-tropical seasons. These insects are not actually worms, as their name would suggest, but are instead a type of lawn caterpillar that has over twenty different species. It is unlikely that you will notice an infestation of tropical sod webworms until it has become severe, but even minor infestations can cause issues to your lawn.

Tropical sod webworms are an insect that lives in your grass from the root. They are born in these locations and feed on the leaves at the base. This can cause your grass to die, appearing dry and brown in your yard.

About Tropical Sod Webworms

Tropical sod webworms are born in the springtime, as most insects in this species lay their eggs around this time. The lifespan of a tropical sod webworm is quite short by our standards, as it only takes ten weeks for them to grow from egg to adult. However, this doesn’t mean that they can disappear easily. As they grow quickly, it is possible that your garden is being infested by several generations of sod webworms.

Unlike a lot of insects, winter will not kill off tropical sod webworms, so leaving them to the elements is not an effective treatment. Sod webworms coat themselves in a silk lined cocoon during the winter months to help them survive. As soon as spring comes around again, the tropical sod webworms will start feeding on your lawn once more.

How Do Tropical Sod Webworms Damage Lawns?

Once tropical sod webworms mature they become moths which will not damage your lawn. This means that you need to handle the young. When tropical sod webworms mate, the female moths will lay hundreds of eggs which cause problems to your lawn. You are likely to notice a tropical sod webworm infestation during the spring as they hatch.

Tropical sod webworms feed on grass, and their chewing removes the top layers of your lawn, leaving it more vulnerable. As tropical sod webworms grow, they can cover more ground, eating and damaging more of your lawn. This will cause large areas of brown sod, causing your grass to look as though it has been through a drought. The grass will become damaged and brown.

Tropical Sod Webworm Damage Vs. Drought Damage

If you have a tropical sod webworm infestation, you may not even notice that this is the case. Many people mistake the damage that tropical sod webworms cause as damage caused by a drought. As these insects attack your garden during the hotter seasons, this is an easy mistake to make. Tropical sod webworms damage your lawn by feeding on it, which kills the plants from the base. This makes them dry, have stunted growth, and become brown.

These are also signs of a drought which is very common in tropical seasons. However, if you try to treat your lawn for drought when you actually have a tropical sod webworm infestation, then you could be making the issue worse.

It is important to remember that drought will affect the whole lawn, causing it all to be brown and dry. However, a tropical sod webworm infestation will usually only be in the sunny locations of your lawn. They are common in dry spots in the yard, such as along driveways or curbs. If you notice that your lawn is dying in small sections, then it is likely that you have a tropical sod webworm infestation and need to treat it accordingly.

This is why it is vital for you to learn the lifecycle of sod webworms, so you know when it is best to act.

You can remove sod webworms from your lawn using pesticides or insect killers. These solutions work best when applied in specific locations.
