About Lice on wolves (Trichodectes canis)
The lice that are found on wolves are usually Trichodectes canis.
Commonly Affected Species:
Signs Of Disease
Trichodectes canis on wolves is typically found in low numbers. Lice are small, about the size of a flattened rice grain, and are usually found in the groin and armpits. In large numbers, the lice tend to cause irritation and itching, which results in a diamond shaped area of hair loss over the back of the affected animals.
Where is Disease Found?
Trichodectes canis is found in wolves across most of North America. The louse has been documented on wolves in Idaho.
How Can I Protect Myself?
Trichodectes canis is a canine specific louse and will not affect humans. The lice can transfer from wolves to domestic dogs. Keep domestic dogs away from wolves and wolf carcasses.
Samples to Collect
If there is concern about this condition, contact a conservation officer or an Idaho Department of Fish and Game Regional Office. Appropriate samples can be collected for testing if deemed necessary.
Can I Eat The Meat?
Meat from wolves infested with Trichodectes canis is suitable for human consumption.
What is IDFG doing to help manage this disease?:
Trichodectes canis is present in wolves in Idaho, but heavy infestations are usually restricted to individual animals. Fur quality can be reduced by high numbers of lice. Control of lice in wild wolves can be done, but is expensive and time consuming.
