Chinch Bug

Lawn grass is often attacked by many types of chinch bugs. There are several types of chinch bugs that feed on lawn grass. When these bugs start feeding, they release an anticoagulant. This causes the lawn grass to stop absorbing water. The grass will eventually wither and die due to lack of water.

Cutworms are about 2 inches long and are brown or gray with some striping. There are several species of cutworms. The adult cutworm lays eggs on the grass and the eggs hatch into worms.

The worms stay hidden during the day and feed at night. They feed at the base of the grass. The stems are completely bitten off. On closer inspection, you will be able to see the sheared off the grass.


Aphids are small and reproduce quickly. It is often tricky to get rid of them. You will be able to spot the damage if you look for yellow leaves or misshapen grass or a sticky substance on the plant.

Always read the label to determine which type of chemicals can be used on specific varieties of grass. If you are unsure about a product, you can apply it to a small area of the lawn. If the product is successful, you can apply it to other areas of the lawn.
