About Dung Beetles

Dung beetles are a beneficial part of the agricultural integrated pest management toolkit, helping to control unwanted pests, such as horn and face flies. These industrious insects play a crucial role in maintaining ecosystem balance by efficiently recycling dung, improving soil quality, and reducing the prevalence of harmful pests.
