Poultry farming is an important activity in animal protein production worldwide, either by laying hen farming or broilers. Over the last decades, the change in production systems with confinement of large numbers of hens has increased productivity and reduced costs; however, it has also increased sanitary issues. In this setting, arthropods that are adapted to poultry houses have gained great importance. They cause direct damage to hens, either by blood spoliation caused by ectoparasites or lesions in the digestive tract (e.g., lesser mealworm) or by indirect damages, by transmitting pathogens or by affecting egg quality, when they attain pest status. Synthetic chemical products comprise the most frequently used control strategy against these pests, with relative efficacy and many side effects. In Europe, some countries also adopt alternative prevention or control measures. In Brazil, however, although there are some groups of researchers that work on developing alternative control, its use is virtually zero. The present review shows a critical overview of this context in Brazil, based on the alternatives that have already been studied and made available, but have not been implemented, yet, and the potential stumbling blocks created by the very poultry market against these advances.
