Superworms, a type of beetle larva, are emerging as a promising method for cleaning animal skeletons, as detailed in a study published on July 1, 2026. Conducted by Fatemeh Rastekar and colleagues from Ferdowsi University of Mashhad, Iran, this research highlights the effectiveness of superworms in removing flesh from skeletons without damaging the bones.
Efficiency of Superworms in Skeleton Cleaning
The study tested various numbers of superworms on eight different animal specimens, ranging from a 9-gram Egyptian rousette to a 4.2-kilogram wolf. Over a period of hours to days, the larvae successfully cleaned the skeletons, both internally and externally. Researchers found that using 10–15 grams of larvae per gram of animal specimen optimized cleaning time and minimized potential bone damage.
The results indicated that at this ratio, superworms could clean even delicate bird skulls without causing any skeletal harm. This method contrasts sharply with traditional cleaning techniques that often risk damaging bones or involve hazardous materials.
Advantages Over Traditional Cleaning Methods
Superworms present a safer, more environmentally friendly alternative to conventional skeleton cleaning methods, such as chemical treatments or dermestid beetles. The authors noted that maintaining superworm colonies involves no hazardous substances, significantly reducing the risk of pest infestations in museum collections.
