Rodenticides containing a blue dye are frequently employed for the control of rat populations. The coloration serves primarily as a visual deterrent for non-target species, including pets and wildlife, and can aid in identification should accidental ingestion occur. These formulations typically contain anticoagulant poisons, disrupting the blood clotting process in rodents, ultimately leading to internal bleeding and death.
The use of these rodenticides offers a relatively efficient method for managing rat infestations, particularly in agricultural settings, residential areas, and commercial properties where these pests can cause significant damage and pose health risks. Historically, the development of anticoagulant rodenticides marked a significant advancement in pest control, providing a more effective and targeted approach compared to earlier, more toxic substances. Their continued use reflects a need to mitigate the economic and public health consequences associated with unchecked rat populations.
