The term "wolf worms" is not a scientifically recognized term used to describe parasites in squirrels. It's possible this is a colloquialism or a misinterpretation of a particular parasite. Squirrels, like many other animals, are susceptible to various internal and external parasites. Understanding these parasites and their life cycles is key to understanding when a squirrel might appear to be "losing" them.
Common Parasites Affecting Squirrels and Their Life Cycles
Several parasites can affect squirrels, and the timing of their shedding or expulsion varies depending on the specific parasite and the squirrel's overall health. Let's look at some possibilities:
1. Fleas:
- What they are: Common external parasites that feed on the squirrel's blood.
- When they're shed: Squirrels can groom themselves to remove fleas, but a significant flea infestation will require veterinary intervention. There isn't a specific time of year when squirrels "lose" fleas, as the infestation can persist throughout the year.
- Signs of infestation: Excessive scratching, hair loss, and restlessness.
2. Ticks:
- What they are: External parasites that attach to the skin and feed on blood. Some ticks can transmit diseases.
- When they're shed: Ticks will detach from the squirrel once they are engorged with blood. This can happen at various times throughout the year, depending on the tick species and environmental conditions.
- Signs of infestation: Visible ticks attached to the skin.
3. Mites:
- What they are: Tiny external parasites that burrow into the skin, causing irritation and mange.
- When they're shed: Mite infestations can persist for extended periods, requiring treatment. The mites themselves aren't shed in a single event but require veterinary intervention to eliminate.
- Signs of infestation: Hair loss, scabbing, intense itching.
4. Intestinal Worms (e.g., Roundworms, Tapeworms):
- What they are: Internal parasites that live in the squirrel's digestive tract.
- When they're shed: The eggs of intestinal worms are shed in the squirrel's feces. This happens continuously during an active infestation. The worms themselves are not typically shed but are passed through the feces. Treatment is necessary to eliminate these parasites.
- Signs of infestation: Weight loss, diarrhea, lethargy.
What to Do if You Suspect Parasite Infestation in a Squirrel
If you observe a squirrel exhibiting symptoms of a parasite infestation (e.g., excessive scratching, hair loss, lethargy), it is crucial to avoid handling the animal. Wildlife rehabilitation centers possess the expertise and resources to properly assess and treat sick or injured wildlife. Contact your local wildlife rehabilitator for advice and assistance. Do not attempt to treat the squirrel yourself; improper treatment can be harmful.
Conclusion
The phrase "wolf worms" is likely not a scientifically accurate term. Squirrels can be affected by various internal and external parasites throughout the year. If you suspect a squirrel has parasites, contact your local wildlife rehabilitator for appropriate assistance. Remember, wild animals are best left to the care of professionals.
