The product does not only control the pest and ectoparasite infestations, but it also does not have any negative effect on the animals – it does not decrease their resistance, does not increase the mortality and it increases the laying performance. It is the only product available for use at every age/stage of the breeding process. It does not cause increased hunger of the animals connected to their weakening. It can be used in the presence of animals.

Dergall Can Control A Wide Range of Pests


The house fly, Musca domestica Linnaeus, is a well-known cosmopolitan pest of both farm and home. It is the most common species found on hog and poultry farms, horse stables and ranches. Flies commonly develop in large numbers in poultry manure under caged hens, and this is a serious problem requiring control. Although this fly species does not bite, the control of Musca domestica is vital to human health and comfort in many areas of the world. The most important damage related with this insect is the annoyance and the indirect damage produced by the potential transmission of pathogens (viruses, bacteria, fungi, protozoa, and nematodes) associated with this fly.

Darkling Beetle

Darkling beetles can be found in poultry houses worldwide because the house environment is ideal for their growth and survival. They are vectors for common poultry viruses such as Infectious Bursal Disease Virus (IBDV), Marek’s Disease Virus (MDV) and Reovirus; bacteria such as E.coli and Salmonella spp. and protozoa such as Histomonas meleagridis. Diseases can be spread by darkling beetles by direct contact, recontamination of the disinfected environment by the reuse of litter or by being ingested by the bird directly. They can also cause significant damage to poultry housing.

Red Poultry Mite

Dermanyssus gallinae
Red poultry mite is the most damaging parasite of laying hens worldwide. Economic losses from poultry mite infestation severely affect the productivity of the egg industry. Consequences of red mite infestation in a layer operation include primarily a negative impact on feed conversion ratio, a drop in egg production, an increase in downgraded eggs, a higher susceptibility to poultry diseases, and more dead animals. A still widely quoted estimate for the cost of mite control and production losses is €130 million annually. In addition to its effects on chicken’s health and welfare, red mite infestation also poses public health concerns, due to the role of D. gallinae as a disease vector of zoonotic diseases, and its medical impact on humans living or working in close association with poultry.

Scaly Leg Mite

Knemidocoptes mutans
The scaly leg mite infests poultry and other domestic and wild birds worldwide. It does not suck blood but burrows into the skin tissues under the leg scales, causing inflammation and exudation. It is more common in old birds whose legs become thickened, crusty and deformed.

The life cycle can be completed in 10 to 14 days and occurs entirely on the host. It is quite contagious and the birds often get the mites from the ground. It is uncommon in industrial operations but can be a problem in traditional and backyard chicken coops.
