Your lawn can be seriously damaged by insects and other pests, making it look patchy and brown. Common lawn insects can be hard to spot but are easy to detect once they begin to eat your grass. Grubs, which feed on the roots and leaves of grass plants, are the most destructive types of lawn pests.

This kills the grass above ground and prevents new seedlings from taking root. Chinch bugs, armyworms, and sod webworms are also common lawn pests. Although most lawn bugs are harmless, they can quickly become a problem.

There are many effective ways to manage pests on your lawn. Regular mowing and watering will keep your turf healthy, and make it less attractive for pests. To kill existing pests and prevent them from forming new ones, you can use insecticides. These steps will ensure that your lawn remains green and healthy for many years to come.

What are some common lawn diseases?

Brown patches, fairy rings and rust are some of the most common lawn diseases. You can prevent these diseases by keeping your lawn healthy and following the proper lawn care practices. You may need to treat your lawn with a fungicide if it develops a disease.

Brown patch: This fungal disease causes brown patches on lawns. This is more common in hot, humid conditions. You can prevent brown spots by watering your lawn in the morning, and not during windy weather.

Fairy ring: This fungal disease causes mushrooms to grow on lawns. It’s most common in areas that are damp and shaded. You can prevent fairy rings by aerating the soil and improving drainage.

Rust: This fungal disease causes tiny, orange-brown spots on the leaves of grass. This is more common in humid conditions. You can prevent rust by mowing your lawn frequently and avoiding watering in windy conditions.

What are some common lawn pests?

Common lawn pests include chinch bugs and grubs. You can control these pests with many methods, including traps and pesticides.

Grubs: Grubs, small, white larvae, feed on the roots and leaves of grass. They are most active in the late summer and early autumn. You can control grubs with pesticides and traps.

Chinch bugs: Chinch bug are tiny, black insects that feed off the leaves of grass. They are most active during hot, dry conditions. You can control chinch bug infestations with pesticides and beneficial insects.

Sod webworms: These larvae are small and brown, and feed on grass leaves. They are most active in the late summer and early autumn. You can use traps or pesticides to control sod webworms.

What are some common lawn care problems?

Common lawn care problems are weeds, excessive thatch, and bare spots. Proper lawn care techniques can prevent or resolve these problems.

Weeds: This is one of the most prevalent lawn-care issues. They can be hard to control and may require multiple treatments. You can use herbicides or pull weeds manually to control them. Also, you should regularly mow your lawn.

Bare spots: These can be caused by over-exposure to sun, soil compaction, heavy traffic, and other factors. You may need to correct the problem and improve drainage.

Excessive Thatch: This is an accumulation of dead grass or organic matter on the soil. It can block nutrients and water from reaching the grassroots. You can use a Verticutter or power rake to remove excess thatch.

Identify and treat common lawn pests

Many pests can infest lawns, making them less attractive and causing severe damage. Common lawn pests include chinch bugs and grubs. You can control these pests with many methods, including traps and pesticides.


Cutworms, small and voracious insects that can inflict serious damage on a lawn or garden, are very common. There are many species of cutworms. Most are approximately 2 inches in length and are gray-brown in color. Adult moths are dull gray, with brown or black markings.


Young seedlings are especially vulnerable to cutworms as they will eat any vegetation that they find. The adults lay eggs on the tips and blades of grass in spring. The worms that result will then feed throughout the night, before returning to their hiding places during the day.

After about two to four weeks, the worms will become moths and begin the cycle again. This reproduction cycle may occur up to six times a year in areas that have mild winters. If you want to protect your plants, it is crucial to check for cutworms.

Grubs (Beetle Larvae)

White grubs are larvae of many scarab beetles including Japanese and masked Chafer beetles. These C-shaped, plump larvae eat lawn grass roots just beneath the soil surface in spring, summer and early fall. Grubbs eat the roots of grass plants, causing lawn damage.

This causes the plants to lose water, nutrients and wilt, and eventually die. Additionally, disease organisms can attack grass plants easier because grubs are easy to find. A white grub infestation can quickly decimate a lawn. This problem can be tackled by homeowners who apply insecticides in spring, summer and fall. These treatments will stop the grubs from causing serious damage to your lawn.

Late summer is when grub damage begins to manifest in the form of browning and wilting of the grass blades. Over the next few months, the damage worsens and the turf can be dead or dying by spring. The turf can often be pulled from the ground to expose the grubs beneath.

Grubs love grass and are grub-like eaters. It is difficult to stop grub damage once it has started. Grub-infested lawns are attractive to moles, skunks, and crows. Preventive treatment with an insecticide is the best way to protect your lawn from grubs. You can protect your lawn by applying an insecticide in the early summer.


Although it may sound like something from a science-fiction novel, armyworms are actually very real and can cause serious damage to your lawn. Armyworms, named for their aggressive feeding habits and ability to quickly strip lawns of their grass, are well-known.


Armyworms can be challenging to control once established. They produce up to three generations during the spring and summer. Preventive measures such as regularly mowing your lawn and eliminating any food sources such as dead leaves or overgrown grass are the best defense against armyworms.

There are many pesticides available that can be used to control an armyworm infestation. It is important that you follow all directions as armyworms can quickly become resistant to pesticides.

The Armyworm is one of the most destructive pests to lawns. The Armyworm is a tiny, destructive pest that can cause significant lawn damage in a very short time. Because they move in large numbers, or “armies,” armyworms are known for their ability to quickly remove all vegetation from a lawn. Armyworms are active in the evenings or early mornings and feed on grass stems and blades.

This can cause bare spots on the lawn and skeletonize other leaves. Armyworms can also hide from the sun during daylight, making them hard to spot. It is crucial to act quickly if you suspect you may have an Armyworm problem.

These pests are easy to control, but they can quickly multiply. There are many effective ways to combat these pests. You can protect your lawn by taking proactive steps to prevent these pests from coming back.

Chinch Bugs

Chinch bugs, small black insects that feed on grass leaves, are called “chinch bugs”. They are most active during hot, dry conditions. You can control chinch bug infestations with pesticides and beneficial insects.

By sucking the sap from the grass blades, Chinch bugs can damage lawns. The grass will turn yellow and eventually die. Chinch bugs are most active during the summer so they can cause most of the damage.

You can spray an insecticide on your lawn to control chinch bug infestations. You can also release ladybugs and other beneficial insects into your lawn. These predators will keep the chinch bugs under control.

Sod Webworms

You may have seen sod webworms if you’ve noticed tiny brown and green worms on your lawn. These tiny insects are the larvae from the sod webworm moth and can cause severe damage to your turf. They lay their eggs on grass blades at night and typically have between two and three generations per year.

Within seven days, the eggs hatch, and the larvae of webworms begin to feed. They hide in grassy burrows and weave silken webs during the day. They become adult moths in five weeks. Although they can be quite harmless when they become adults, sod webworms can cause lawn damage. It is important to immediately take action if you suspect you have an infestation.

The sod webworms, which are small brown larvae, feed on the grass leaves. They are most active between late summer and early autumn. You can use traps or pesticides to control sod webworms.

Sod webworms are able to cause lawn damage by eating the grass blades. The result is small patches of grass that are dead. The larvae become moths as they mature and can fly great distances to find food.

You can spray an insecticide on your lawn to control sod webworms. To catch them before they lay eggs, you can set up traps.


Pests can quickly destroy a lawn, as any gardener will tell you. If they are not controlled, they can do extensive damage and leave brown patches. There are many steps you can take in order to prevent and control lawn pests. Cutworms can be controlled by regularly mowing your lawn and clearing out any debris.

You can control armyworms by using bait or traps. Sod webworms are best controlled by maintaining a healthy lawn. Pesticides and nematodes can be used to control grubs, while insecticides can be used to control chinch bugs. These are just a few steps to protect your lawn against pests.
