Dermanyssus gallinae is one of the most dangerous external parasites in domestic and wild birds. Through skin pricking, blood suction and salivation, it causes anaemia, pruritus, anxi- ety and insomnia of birds. The result of the invasion is a decrease in laying hens, exposure to constant stress, immunosuppression, anaemia and more frequent falls of birds. In contrast, human symptoms include urticarial lesions, skin nodules causing human dermatitis (gamasi- dosis), often found in urban environments associated with pigeons. In addition, D. gallinae can be a vector and reservoir of pathogens dangerous for humans and animals, including Coxiella burnetii, Borrelia afzelii, Salmonella gallinarum, influenza virus A (Raele et al., 2018, Pugliese et al., 2018, Sommer et al., 2016). Increasing evidence suggests that D. gallinae populations have signif-icant genetic resistance to commonly used drug classes, including many synthetic pyrethroids (Piskorski et al., 2011; Fiddes et al.,2005). It is therefore necessary to look for alternative methods of controlling and limiting these ectoparasites. In addition, there is an increase in consumer demand for safe and food-free residues. Consumers need alternative and natural means. Many plant species produce toxic secondary metabolites that limit the attacks of insects and can thus limit the spread of insects on new hosts
