Infestation by Varroa

Last edited: 4/16/2026

Overview

Varroa mites are parasitic pests that infest honey bee colonies, leading to significant colony decline and potential disruption of pollination services 1.

Diagnosis

  • Visual inspection of adult bees for mites or damaged brood patterns 1.
  • Sugar roll test to quantify mite infestation levels 1.
  • Hemoglobin spot test for assessing brood infestation 1.

    • Management

  • Implement integrated pest management strategies including screened bottom boards and drone brood removal 1.
  • Use acaricides such as formic acid or thymol-based treatments, applied according to product guidelines 1.
  • Introduce mite-resistant bee stock to bolster colony resilience 1.

    • Special Populations

  • No specific guidelines provided for pregnancy, pediatrics, or elderly populations in relation to Varroa infestation management 1.
  • Comorbidities in beekeepers may affect treatment adherence but do not alter primary management strategies 1.

    • Key Recommendations

  • Employ regular monitoring techniques like sugar roll tests to detect Varroa infestations early (Evidence: Expert opinion 1).
  • Integrate physical management methods with chemical treatments to control mite populations effectively (Evidence: Expert opinion 1).
  • Prioritize the use of mite-resistant bee strains to enhance colony survival rates (Evidence: Expert opinion 1).
