Brown patches in lawns can be caused by various factors, including drought, dog urine, and pests. Homeowners often blame grubs, but this is not always the case. In fact, small populations of grubs are usually not problematic.

Further information is available on how to determine if grubs are the cause of brown patches in lawns. Grubs are the early life forms of certain beetles and live under lawns and other plants.

Details on how to test for grubs and what to do if they are found can be found through the Odessa American, which has more information on this topic.
