High economic impact of the poultry red mite (Dermanyssus gallinae), the lack of natural acaricides and the resistance of present chemicals have all led to the need to find new ways to control these ectoparasites. One promising alternative method of control focuses on employing repellent effects of selected essential oils against poultry red mite. This experiment was conducted in order to investigate the repellent effects of thyme (Thymus vulgaris L.), lavender (Lavandula angustifolia L.) and oregano (Origanum vulgare L.) on poultry red mites. The best results were observed for lavender essential oil (96% mortality after 72 h) and thyme (82% mortality after 72 h) at a dose of 0.15 mg/cm2. In addition, thyme and lavender essential oils showed significant (p < 0.05) persistent toxic effects 15 and 30 days post application to filter papers. Thyme was the most effective (100% mortality at 72 h), followed by lavender (78% mortality after 72 h). Results have showed that the thyme and lavender essential oils exhibited promising results when tested in vitro for toxic and repellent effects against poultry red mite. Based on the obtained results we suggest that future experiments should focus on in vivo experiments using these oils in laying hens farm conditions.
