The answer to 'lawn mowing pests' is that common lawn mowing pests include grubs, chinch bugs, and mole crickets. These pests can damage your lawn by feeding on the grass roots and causing brown, patchy areas. Symptoms include wilting, thinning, or discolored grass, and you may also see the pests themselves or their tunnels and damage.
For minor infestations, you can often treat the problem yourself using insecticides or natural methods like introducing beneficial nematodes. However, for larger or persistent issues, it's best to call in a professional lawn care service. They have the expertise and equipment to properly diagnose and treat the problem to restore your lawn.
