The PRM D. g. is one of the most serious and widespread pests of poultry production. It is a worldwide ectoparasitic pest , showing genetic variation between the UK, France and Italy . D. g. hides in cracks and crevices in poultry units and infests the birds only briefly for blood meals, mainly at night . This haematophagous mite feeds rapidly from its host (in comparison with ticks for example) and can survive several months without a blood-meal. The mites enter poultry houses through open wall fans, wall inlets and air chimneys  or are brought by staff, bird cages, crates or wild birds. In recent years, the frequency of D. g. infestations in laying hens has increased in Europe, as has its pest status.
D. g. can have a significant economic impact in poultry production by causing a reduction in egg production, loss in body weight of birds, and a reduction of welfare of laying hens . D. g. may also cause dermatitis in humans [6, 7]. Infestation with D. g. can cause irritation and restlessness in affected hens and can even result in the death of birds . It is reported that the death rate among the hens can rise from 1 to 4%, with a reduction in laying performance of up to 10%, as a result of infestation. Downgrading of egg quality in poultry affected by D. g. has also been observed [9, 10].
In addition to causing 'direct' losses in poultry production systems, D. g. has also been described as a potential vector of several bacteria and viruses of concern to poultry, among them several food borne pathogens [11–14].
In order to assess levels of D. g. infestation on farms different mite traps have been evaluated and used as indicators to inform control decisions [15, 16]. Effective options available for control of D. g. are limited . The use of inadequate, ineffective, or even illegal chemicals have been responsible for increases in infestation rates due to the spread of acaricide resistance now common in many countries . Nevertheless, some products are still being developed and used with some success. For example,  found that phoxim 50% is an effective acaricide against D. g. with  showing the same to be true of spinosad.
D. g. is widespread among farms in Kosovo and might cause high economic losses within the national poultry industry.
