Treating Roundworm Contamination in a Rural Yard

Roundworm (Toxocara) eggs from dog feces persist in soil for years and pose a risk to children and pets. New York's strict pesticide laws limit chemical options.

Immediate Actions

• Hire a service to remove all visible feces immediately.
• Consult a veterinarian for pet deworming protocols.
• Contact a local NY-licensed nursery or Cornell Cooperative Extension for approved sanitizers.

Potential Treatments

• Consan (quaternary ammonium) may be labeled for outdoor use in some states; verify NY registration.
• Steam sterilization of small areas is effective but impractical for large yards.
• Solarization (clear plastic for 4–6 weeks in summer) can reduce viability in top 2–3 inches.

Prevention

• Prompt feces removal.
• Cover sandboxes when not in use.
• Wash hands after yard work.

Professional guidance is essential due to regulatory constraints.
