The answer to 'sod installation pests' is that common pests that can damage newly installed sod include grubs, moles, voles, and chinch bugs. These pests can feed on the roots and cause the sod to die or fail to establish properly. Symptoms include discolored, thinning, or patchy grass, and visible tunneling or damage.
To prevent and treat sod pests, you can use integrated pest management techniques like applying beneficial nematodes, using pest-resistant sod varieties, and spot-treating affected areas with insecticides or rodent control methods. For severe infestations or if you're unsure of the cause, it's best to call a professional landscaper or pest control expert who can properly diagnose and treat the problem.
