Pest Control – The Top 5 Common Pests That Damage Your Lawn and How to Eliminate Them

Billbugs

Billbugs are a common lawn pest in Utah, particularly in the northern regions. These weevils have a distinctive snout and feed on grass stems and crowns, leading to brown patches and weakened turf. To control billbugs, closely monitor your lawn for signs of damage, such as thinning or yellowing grass. Implementing strong pest control measures by applying an insecticide labeled for billbugs at the appropriate time, usually in early summer or when adult billbugs are active is a good pest control measure. Adequate irrigation and regular mowing practices that promote healthy grass growth can also help prevent billbug infestations.

Sod Webworms

Sod webworms are prevalent in Utah and can cause significant damage to lawns. These caterpillars feed on grass blades and create small burrows in the thatch layer, resulting in brown patches and thinning turf. To eliminate sod webworms, monitor your lawn for signs of infestation, such as irregular brown spots or an increase in bird activity. Applying an insecticide labeled for sod webworm control, following the product instructions, can effectively eliminate these pests. Additionally, maintaining proper lawn care practices, such as regular mowing and adequate watering, helps discourage sod webworm infestations.

Aphids

Aphids are common lawn pests in Utah, particularly on ornamental plants and grasses. These small insects suck sap from the grass blades, causing yellowing and stunted growth. To control aphids, regularly inspect your lawn for signs of infestation, such as curling leaves or the presence of sticky honeydew. Encourage natural predators, like ladybugs, by planting flowering plants nearby. If necessary, apply insecticidal soaps or horticultural oils to target aphids specifically. Proper lawn maintenance, including regular fertilization and watering, helps keep grass healthy and less susceptible to aphid damage.

White Grubs

White grubs, the larvae of various beetles, can be a significant problem in Utah lawns. They feed on grassroots, causing brown patches that detach easily. To control white grubs, inspect your lawn for signs of damage, such as wilting or loose turf. If an infestation is detected, apply a targeted insecticide labeled for white grubs at the appropriate time, usually in late summer or early fall when they are actively feeding near the soil surface. Promote a healthy lawn through proper irrigation and regular fertilization, as healthy grass can withstand white grub feeding to some extent.

Ants

Ants are a common nuisance in Utah lawns, and while they do not directly damage the grass, their nesting activities can create unsightly mounds and disturb the turf. To manage ants, locate and destroy their nests using targeted insecticidal baits or granules. Focus on treating problem areas and the perimeter of your lawn. Practicing good lawn hygiene, such as removing food sources and keeping the area free of debris, can also help deter ant infestations.
