What causes coyotes to get lice? The last handful that I have caught all have it.
Is it an overpopulation thing or just luck of the draw? I hope its not just luck, or mine is terrible. And I'm not sure its because of population since population seems to be down around me.
Anyone have an answer?

Any parasite infestations in animals increases with population increases of those animals.

Some things are density independent. They say lice comes from dogs.

I heard the same thing Dirt said: lice comes from contact with domestic animals, mostly dogs and cats.

I once caught two wolves that were lousy, and their pelts were worthless.

Just never hear about lice in dogs or cats around here I need to ask my Vet and see what she says is it spreads in yotes so fast why not dogs and cats.

"Canine Biting Louse (Trichodectes canis)

In the wingless insect suborder of chewing lice (Mallophaga), Trichodectes canis is the louse species that most commonly feeds on domestic dogs and other canids such as coyotes, wolves, and foxes, which may come into contact with dogs."


Not from cats.

Never owned a cat. I thought they get lice too. Thanks, Dirt.

Cats can have lice. Just not the ones canines get.

" Unlike ticks and other parasites, the 2,800 species of biting lice described worldwide are very host-specific."

I wonder if housecat lice ever spread to bobcats and lynx?

Things I have noticed about lice in yotes since I learned to identify them.

1. Areas that have lice seem to get more percentage of the population later in winter.

2. if presant earlier in the fall, they were presant in almost every one I caught. (bad year)

3. I have seen it very bad one year, and louse free the next. (how can this happen)

4. Wet or dry years seem to have no effect on the amount of lice.

5. My dog is with me everyday on the trapline. She has not had any sign of catching lice.

6. No one seems to have any solid answers about them. I have googled lice till I'm sick and can't get answers, except generalizations. Can't find where any studies have been on lice.

7. The economic hit is great in the overall scheme of trapping. I personally have thrown away lots of coyotes in several states, which equates to lots of dollars. It is a widespread issue, all over the west and east, from down south to clear up in Canada, I have heard reports. I for one am suspect of simply saying it comes. from dogs! I never see a dog in the condition that the wild canines are seen in quite regularly.

Lice Found On Kenai Wolves
by Ted Spraker
hen biologists on the Kenai Peninsula talk about W "lousy" wolves, they aren't making a value judgment. To varying degrees, wolves on the peninsula have been infested with lice since at least 1982. For political, practical,
and economic reasons, it appears as if they will always be. Trichodectes canis (T. Canis) is the scientific name of this louse, which is fairly common on domestic dogs in warmer environments. According to Dr. Charles Schwartz, who led the initial investigation of the Kenai infestation, T. canis has been reported infrequently on coyotes and red and gray wolves in the contiguous United States and southern Canada. Its occurrence on more northern populations of wild canids was undocumented before the Kenai infestation. We assume that Kenai wolves were
exposed initially by infested free-ranging dogs.
T. canis feeds on hair and other debris near the skin surface.
Wolves scratch and rub in response to irritation caused by lice, resulting in moderate loss of guard hair on adult wolves and extensive loss of guard hair and under-fur on pups. This scratch­ ing sometimes becomes so severe that body secretions (called sebum) collect on th~ skin and hair. Sebum mats the hair, reducing its insulating quality and causes the animal to smell like rotten flesh. Scratching and biting at lice also causes open sores which number in the hundreds in severe cases. (Infestation also may impair the ability of wolves to survive during periods of stress.) Below-normal weights have been documented in infested wolves, although mortalities have not. Additionally, lice infes­ tation detracts from the appearance of wolves and significantly reduces the value of pelts to trappers and hunters. '
The presence of lice was detected during the winter of 1981­ 82 when a trapper submitted poor quality pelts of seven wolves he had taken from the Bear Lake and Point Possession packs, two of nine packs identified in the northern portion of the peninsula.
By the following winter, the three remaining packs (Skilak Lake, Elephant Lake, and Swanson River) in the northern portion of the peninsula were infested. By the winter of 1983-84 the infestation had spread to the eastern half of the Kenai. In subsequent years, "lousy" wolves were reported from one of three packs in the west central portion of the Kenai and two of five packs in the southwestern part of the peninsula.
The initial plan by the Department of Fish and Game (ADF&G) and the U.S. Fish and Wildlife Service was to remove, by aerial shooting, all infested wolves (a total of 14) in the Bear Lake and Point Possession packs in March 1982. By closing wolf hunting and trapping seasons in the northern section the following year, we thought wolves from adjacent areas would have moved into the vacant territories and re-established their numbers. How­ ever, before a final decision was reached, snow began to melt. This made tracking difficult and the probability of success questionable. Success for this program meant all 14 wolves had to be removed or treated. There was also public opposition to killing the wolves. As the snow faded, so did the only opportunity
likely to eradicate the infestation. By the following winter, the lice had spread to all five packs in the northwest Kenai.
The next step was a treatment program with ivermectin, a drug which is used to kill both internal and external parasites. Success was short-lived. Ivermectin is able to kill lice for less than one year after treatment. Therefore, it was necessary to re­ medicate entire packs if a single animal escaped capture initially. In cases where the entire pack was captured and treated, the pack remained clean only until an infested wolf joined the pack. Recaptures and reports from trappers showed successfully treated packs remained clean from one to three years.
The treatment program temporarily succeeded in controlling the spread of lice. However, the enormous time and cost prompted abandonment of the program. Ivermectin is also effective if it is ingested. Biologists dropped small pieces of meat treated with ivermectin at the site of fresh wolf-killed moose. Examination of pelts brought in by hunters and trappers sug­ gested pups ate the treated bait. Adult wolves apparently refused to eat the bait and remained infested. These adults could serve as a source of lice to reinfect the other pack members.
Although free-ranging dogs are thought to be the source of the original infestation, natural dispersal by wolves probably ac­ counted for its spread and the reinfestation of wolves treated with ivermectin. According to six wildlife parasitologists who evalu­ ated the situation, the entire life cycle of T. canis is spent on the host. Lice cannot survive for any length of time off the host. Close association between hosts, such as that occurring during the care of young, copulation, and contact between members of a pack, provided the greatest opportunity for transfer of lice.
In the winter of 1990-91, T. canis was documented in at least five packs on the Kenai Peninsula. The infestation has again begun spreading across the peninsula, despite the extensive agency efforts during the mid-1980s. Three tagged wolves from the peninsula have moved to interior Alaska. However, there is no evidence that the lice problem has spread to the mainland.
Disagreement over a decision to kill a few infested wolves in 1982 probably cost us the only realistic opportunity we had to eliminate the problem. Kenai residents, who were close to and familiar with the issue, clearly supported removal of the 14 infested wolves as the only practical attempt to eliminate the infestation. However, when a public meeting was held in An­ chorage, several animal-rights groups protested the recom­ mended action enough to delay it. Subsequent developments proved unfortunate for wolves and for the people who appreciate wolves. When similar situations arise in the future, the impor­ tance of long-term benefits to an entire population of animals should take precedence over the short-term fate of a few individual animals.

Thanks for that article, Drasselt. Like I said, I have trouble believing the general explaination that it comes from dogs. And the real kicker of this, is I have seen it so bad in coyotes here that I quit trapping them, was throwing 99% away. The next year, went out and set traps, fearing the worst, and didn't catch hardly any with lice. WTH is up with that? How do they clean up? None of it makes any sense!

The Kenai Peninsula was where I snared my two lousy wolves. They came from a different pack than the ones referenced. The two I caught, a male and female, were on their own, maybe starting a new pack. If so, I wiped out an incipient pack of infected wolves.

Are these lice capable of playing host to typhus ?


It'd be a cold day in (This word is unacceptable on Trapperman) before I'd mess with cayutes if they were carrying typhus. frown
