Common Pests of Bermuda Grass
Bermuda grass is susceptible to several pests that can cause significant damage if not managed properly. Here are some of the most common pests to watch out for:
1. Armyworms
Armyworms are caterpillars that can quickly devastate Bermuda grass. They are often more active in late summer and early fall.
– Look for irregular patches of brown grass, as this is a sign of their feeding.
– They can be controlled using insecticides or by introducing natural predators.
2. Chinch Bugs
Chinch bugs are small pests that suck the sap from Bermuda grass, leading to yellow or brown patches.
– These bugs thrive in hot, dry weather and can multiply quickly.
– Regular watering and monitoring can help control their population.
3. Grubs
Grubs are the larvae of various beetles and feed on the roots of Bermuda grass.
– Signs of grub infestation include wilting grass and the presence of birds pecking at the lawn.
– Applying beneficial nematodes can help reduce grub numbers in the soil.
4. Mole Crickets
Mole crickets burrow into the soil, disrupting the root system of Bermuda grass and causing it to die.
– Affected areas may feel spongy underfoot.
– Insecticides are typically used to control their populations.
5. White Grubs
White grubs are often found in the soil and can severely damage your lawn by eating the roots of Bermuda grass.
– Affected grass will start to dry out and die.
– Using nematodes or milky spore can help control white grub populations.
Common Diseases of Bermuda Grass
Alongside pests, various diseases can affect Bermuda grass. Here are some common diseases to be mindful of:
1. Brown Patch
Brown patch is a fungal disease that appears as circular brown patches on the lawn.
– It is most prevalent in warm, humid conditions.

2. Anthracnose
Anthracnose is another fungal disease that can affect Bermuda grass.
– Symptoms include dark, sunken spots on the leaf blades and a general decline in grass health.
– Aeration and proper turf management are crucial for preventing this condition.
3. Dollar Spot
Dollar spot is a common issue that manifests as small, round patches of dead grass.
– These patches usually measure about the size of a silver dollar.
– Keeping your lawn well-fertilized and properly watered can help prevent this disease.
4. Leaf Spot
Leaf spot is characterized by dark, sunken lesions on the leaves.
– Affected grass can become weakened and more susceptible to other diseases.
– Fungicides can be used to manage leaf spot effectively.
5. Rust
Rust is noticeable due to the orange or yellow spores that form on the grass blades.
– It often occurs during hot, dry weather, particularly when Bermuda grass is under stress.
– Regular mowing and ensuring good air circulation can reduce rust development.
