Different types of pests such as armyworms, caterpillars, and cutworms often infest lawns and can cause serious problems. The first step before treatment is identifying the kind of pest in your lawn. If you are not sure of the type of pests in the lawn then it won’t be easy to deal with them. Below are some guidelines and tips that can help in the identification and treatment of lawn pests.

Grub Worms

If you see brown patches in the lawn it is likely they have been caused by white grubs. These pests feed on grass roots and the grass begins to dry on the surface. However, dig around the grass roots and see if this is the real cause of the brown patches since other factors such as improper application of herbicides and pesticides, uneven irrigation, and pet urine can cause similar problems.

After you’ve dug around the roots see if there are any grubs within an area of one square foot. Treat the lawn for grub worms if you find at least six of them within the dug area. When choosing treatment, it is recommended to use the least toxic option available. Treatments should be applied at the right time and applied correctly.


Many people assume caterpillars are less harmful and can’t cause any damage in their lawn. While this could be true it is important to note that these pests can result in serious problems especially when in large numbers. The best way to check for their presence in your lawn is through a drench test. You can apply a mixture of water and dishwashing liquid (four tablespoons) on a section of the yard and watch the area for at least ten minutes. This will help you find out the extent of infestation before proceeding for pest treatment.

Chinch bugs

You can prevent the infestation of these pests in the lawn through regular irrigation/watering as well as removing thatch during fall. If you see yellow patches in your lawn it is an indication of their presence. Leaving these pests in a lawn causes the grass to be easily stressed by the hot weather. You can apply insecticides in case control measures don’t work.
