Wildlife Damage Management for Cropland

Pest Control · November 2025 · 5 min read

Wildlife damage to crops costs American farmers hundreds of millions of dollars annually, and the problem is growing as deer, geese, and wild hog populations expand. Effective management combines physical barriers, deterrents, and population control tools matched to the specific species causing damage. Knowing your legal options and available assistance programs makes dealing with wildlife damage less frustrating.

Deer and Goose Damage

White-tailed deer damage crops by browsing soybeans, alfalfa, and vegetables, with losses concentrated along wooded field edges. High-tensile electric fencing (8 feet tall with baited wires) is the most reliable exclusion method for high-value crops. For larger acreages, deterrents like motion-activated lights, noise makers, and repellent sprays provide temporary relief but lose effectiveness as deer habituate.

Canada geese damage winter wheat and young corn by grazing and trampling. Grid wire systems with mylar tape strung across fields can deter landing in small areas. Depredation permits allow lethal control when non-lethal methods fail, and most states have liberal goose seasons that help manage resident populations.

Wild Hog Control

Feral hogs cause severe damage by rooting up planted fields, damaging levees, and contaminating water sources. They are one of the most destructive invasive species in American agriculture. Trapping with large corral traps that capture entire sounders is the most effective control method. Shooting individual hogs has minimal impact on population size.

• Use trail cameras to pattern hog movement before setting traps
• Pre-bait for 1 to 2 weeks before activating the trap
• Contact USDA Wildlife Services for professional assistance with large populations
• Report new sightings to your state wildlife agency immediately

Permits and Damage Claims

Most states issue depredation permits that allow out-of-season harvest of wildlife actively damaging crops. Application typically requires documentation of damage and evidence that non-lethal methods have been attempted. Contact your state wildlife agency or county extension office for specific permit requirements and application procedures.

Some states and federal programs offer compensation for verified crop damage from wildlife. USDA Wildlife Services provides free technical assistance and can conduct population surveys, install deterrents, and implement direct control measures. Document all damage thoroughly with photographs, GPS locations, and yield loss estimates to support any claims.
