Myiasis in animals refers to infestations caused by fly larvae that develop on the skin or in wounds. These larvae hatch from eggs laid by flies, typically on moist or injured skin. Once hatched, the larvae feed on the animal’s tissue, leading to potentially serious damage. Infestations are most common in summer and affect mainly weakened, soiled, or paralyzed animals.
What is Myiasis?
Myiasis is a parasitic skin infestation caused by fly larvae:
- Larvae range from a few millimeters to several centimeters in size
- Commonly appear in open wounds or on damp skin
- Frequently occurs during warm weather
How to Diagnose Myiasis
Diagnosis is usually straightforward:
- Visible larvae moving in or on the wound or skin
- Presence of a red, oozing, painful wound
- Often accompanied by a foul odor
A visual inspection is typically enough to confirm the infestation. The veterinarian may suggest additional tests if a secondary infection is suspected.
Treating Myiasis in Animals
Effective treatment includes several steps:
- Addressing the underlying issue: treating wounds, infections, or hygiene problems
- Cleaning the affected area: shaving and thoroughly disinfecting the wound
- Manual removal of larvae: with or without anesthesia depending on the condition
- Surgical debridement: necessary for deeply embedded larvae
- Medication: antiparasitics, antibiotics, pain relievers, and anti-inflammatories as needed
Ongoing veterinary follow-up is essential to monitor healing and prevent recurrence.
Prognosis and Prevention
The prognosis is good if treated promptly. However, it becomes more guarded in animals that are severely weakened or have serious underlying conditions.
To prevent myiasis:
- Maintain strict hygiene
- Regularly inspect wounds and seek veterinary advice when needed
- Avoid prolonged exposure to dirty or damp environments
Why See a Veterinarian?
If your animal has wounds or visible larvae, prompt veterinary care is essential. A veterinarian can:
- Effectively remove the larvae
- Treat the root cause
- Relieve pain and prevent complications
Early intervention is key to protecting your animal’s health and well-being.
