N2  - This study was carried out to assess the efficacy of controlling essential oils i.e Thymol, Cinnamon and Anise oils with different concentrations compared to 65% Formic acid in controlling Varroa destructor mites infesting colonies of Apismellifera during the winter and summer of 2013 season. Randomized complete block design was applied at this study. The apiary was divided into 7 groups (3 colonies / group). Three application of the oils. Average of Varroa infestation level before treatment ranged between 21-29 in winter and from 37-47 in summer. The treatments were significantly effective when applied in summer than the winter season and when used at 30% concentration than those obtained at 15% concentration compared to the control treatment. Average efficacies percentage ranged between 80.95% (Cinnamon oil 30%) to 86.99 (Thymol 30%) in winter and from 67.46 %(Thymol 30%) to 82.16% (Cinnamon 30%). Thymol oil was the best in winter, however, Cinnamon was the best in summer
