**Explanation:**

- **Tragedy Degree: 6**
  - The story involves significant emotional and social setbacks for Ellie. The pest invasion threatens her livelihood, she's wrongly accused by her community, and she faces an angry mob. The emotional weight is moderate, not extreme, but enough to cause a profound impact on Ellie and her reputation.

- **Comedy Degree: 4**
  - There are some lighter elements, especially towards the end when Ellie is exonerated and the community learns a valuable lesson. The ending is positive and hopeful but not overtly comedic or emotionally delightful to give it a higher comedy degree. It falls just short of a moderate comedic effect.
