When should hair bags be attached and how often should they be replaced during the growing season?

• A. Attach in early spring and replace monthly
• B. Attach in mid-summer and replace weekly
• C. Attach in fall and replace quarterly
• D. Attach in winter and replace yearly

Answer: (A)

Hair bags deter deer by releasing a scent that makes browsing less appealing during the actively growing period. Attaching them early in the spring ensures protection starts as soon as new growth begins, when buds and young leaves are most vulnerable to damage. The scent and the bag’s effectiveness fade over time due to weather and exposure, so replacing the bags about once a month keeps the odor fresh and the deterrent strong throughout the growing season. Attaching later or replacing more infrequently would leave plants unprotected during key feeding times, while more frequent changes aren’t typically necessary given how the scent lasts in field conditions.
