    New Idaho trappers encouraged to complete trapper education course

    Beginning on July 1, 2018, every trapper who purchased their first trapping license after June 30, 2011 will be required to attend and pass a mandatory trapper education course before they can purchase an Idaho trapping license.

    Trappers that have successfully passed and are certified through the Idaho voluntary trapper education course are exempt, but new trappers will be required to take the course starting in 2018. People who have taken only a wolf trapping education course are not exempt and must take the Idaho trapper education course.

What Causes This Disease?

Tularemia is a bacterial disease caused by the bacteria Francisella tularensis.

Where Is The Disease Found?

Tularemia occurs in many parts of North America in both the terrestrial and aquatic forms. The disease has been documented in aquatic rodents and rabbits in Idaho but is not common.

Signs of Disease

In rabbits and hares clinical signs include lethargy and ill thrift. Tularemia causes lesions on the spleen and liver which are usually swollen and contain white spots. In humans, signs of Tularemia vary depending on the route of infection. Skin ulcers can be seen, usually on the hands, and typically associated with cuts or scratches acquired while skinning hares/rabbits. Glands can also become quite swollen.
