Myocastor coypus usually digs tunnels on inclines of 45-90º. The biggest damage caused by Myocastor coypus is the feeding of the wetlands with natural vegetation that holds the soil intact. This causes soil erosion. Apart from populations with high density, the damage caused by Myocastor coypus is minimal. However, they are known to damage drainage systems, grains and natural plants. Tunnels sometimes penetrate or weaken the riverbeds that provide irrigation of the fields. Toxoplasmosis, Papillomatotis, Rabies, Eguine encephalomyeletis, Salmonellosis, Paratyphoid, Leptospirosis, Richattsia, Sarcopondiosis, Coccidiosis can be transmitted to Myocastor coypus.
