Common Yard Pests and the Damage They Cause

Yard damage from pests falls into a few broad categories: digging and burrowing, lawn destruction, plant damage, and wood destruction. Knowing which category your problem falls into is the fastest way to narrow down the culprit.

Digging and burrowing pests

Moles create distinctive raised tunnel ridges across lawns as they search for grubs and earthworms underground. A single mole can tunnel 100 feet per day. Moles are insectivores, not rodents, and do not eat plants. However, their tunneling uproots grass and creates tripping hazards. Professional mole removal typically costs $200 to $600. See our mole removal cost guide and how to get rid of moles.

Groundhogs (woodchucks) dig large burrow entrances, usually 10 to 12 inches wide, often near garden beds, sheds, or foundations. They are herbivores and raid vegetable gardens aggressively. Skunks and raccoons dig numerous small to medium holes overnight while foraging for grubs. The torn-up turf pattern from these animals is distinctive: cone-shaped holes, 3 to 4 inches deep, scattered across the lawn. Treating the grub population often solves the digging problem. See our wildlife removal cost guide and raccoon removal guide.

Lawn-destroying pests

Grubs (white grub larvae) are the most common cause of brown, dead patches in lawns. They feed on grass roots just below the soil surface, causing the turf to die and pull up like a loose carpet. Grub damage typically appears in late summer and early fall. An added problem: grubs attract digging animals like skunks, raccoons, and birds, compounding the damage. Professional grub treatment costs $150 to $400 for a typical lawn. See our pest control cost guide for pricing details.

Chinch bugs damage lawns by sucking sap from grass blades, causing irregular dead patches that often start near driveways, sidewalks, or other heat-absorbing surfaces. Sod webworms are caterpillar larvae that feed on grass blades at night, creating thinning patches. Both pests are treatable with lawn-specific insecticides.

Stinging insect nests

Yellow jackets build nests underground and are highly aggressive when disturbed. Ground nests with visible flying insect activity are a safety hazard, especially for children and pets. Paper wasps build open-comb nests under eaves, porch roofs, and overhangs. Carpenter bees drill perfectly round holes into wood decks, fascia boards, and pergolas, causing cumulative structural damage. Professional nest removal costs $100 to $400 depending on the species and location. See our ant exterminator cost guide for related pricing.

Why Yard Damage Identification Matters

Misidentifying the cause of yard damage leads to wasted money and continued destruction. A homeowner who treats for grubs when the actual problem is chinch bugs will not stop the lawn from dying. Someone who traps moles while ignoring the grub infestation that attracted them will see new moles move in. Accurate identification ensures you target the root cause, not just the symptoms.

Timing matters too. Grub treatments are most effective when applied in late summer before the larvae grow large enough to cause visible damage. Mole trapping is most successful in spring and fall when tunneling activity peaks. Yellow jacket nests should be treated in early morning or late evening when the colony is inside the nest. Use our pest control cost calculator for accurate estimates once you know what pest you have.

Seasonal Yard Pest Patterns

Spring: Moles become most active, fire ant mounds appear, termite swarmers emerge, carpenter bees start drilling into wood, and groundhogs come out of hibernation.

Summer: Grub larvae feed on roots (damage shows in late summer), chinch bugs peak in hot weather, yellow jacket colonies reach maximum size, and Japanese beetles feed on plants and lay eggs (future grubs) in lawns.

Fall: Grub damage becomes most visible, skunks and raccoons dig heavily for grubs, voles begin girdling trees and eating bulbs, and yellow jacket colonies become aggressive before dying off.

Winter: Voles create surface runways under snow cover, deer browse on landscape plants, rabbits chew bark from young trees, and mole tunneling continues in unfrozen ground.

When to Call a Professional for Yard Pests

Many yard pest problems are manageable with DIY treatments, but some situations warrant professional help. Call a professional if you have a yellow jacket ground nest (disturbing it is dangerous), if you see mud tubes on your foundation (termites), if wildlife is burrowing under your foundation or shed, or if DIY treatments for grubs or lawn pests have not worked after two applications.

Professional pest control for yard issues typically costs $150 to $600 depending on the pest and the size of the treatment area. Wildlife removal runs $200 to $600 per animal. Termite treatment, if identified as a yard concern, ranges from $200 to $1,500+. For a full breakdown, see our pest control cost guide or when to call an exterminator.
