• Covers large areas
• Readily available
• Effective in all stages
• Long-lasting effects
• Immediate results

Cons:

• Can harm beneficial insects
• Potential toxicity
• Requires careful handling

7. Maintaining Proper Lawn Care

A well-maintained lawn naturally resists webworms. Regular mowing, aeration, and fertilization promote strong, healthy grass. Healthy sod is less susceptible to webworm damage. Reducing thatch buildup removes webworm hiding spots. Proper irrigation keeps grass robust, reducing pest survival rates. Lawn maintenance helps prevent recurring infestations. Practicing good lawn care is essential for long-term pest control. Prevention reduces the need for chemical treatments. This method supports overall lawn health and resilience.
