Maggot infestation

What exactly is a maggot infestation?

A maggot infestation, or medically named myiasis, is a condition when flies lay eggs in open wounds and those eggs develop into maggots. Maggots can be considered as external parasites but cannot be prevented with traditional external parasite prevention. Pets, especially dogs and cats that live outdoors, are more susceptible to this gross condition because they are prone to wounds and scratches and their immune system is usually weakened.
For a fly to lay eggs it is not always necessary to be an open wound. A maggot infestation can occur even in wet, filthy coats covered in urine and feces, which is the perfect feeding ground for the eggs to hatch. After the eggs hatch, the maggots continue to feed on dead or dying tissue.

How do we diagnose and treat maggot infestation?

Diagnosing maggot infestation is easy because we just need to visualize the maggots on the skin, coat or a wound.
The treatment of a maggot infestation should include shaving the coat and removing the maggots either by hand or with a topical treatment that will kill them fast (this depends on the localization of the infested wound). After the maggots are removed, the dog or cat should be on antibiotic therapy.
Some types of myiasis, such as cuterebras, may require surgical removal.
In the end, once all the maggots are removed from the wound, the skin infection should be treated topically too.

How can we prevent a maggot infestation?

The best way to keep our pets away from flies and maggots is to keep their coats clean and if any wound appears then the wound should be treated immediately and kept clean. Old pets or already sick and debilitated pets are more prone to wounds and scratches so it would be best for them to keep them indoors to prevent maggot infestation.
If you suspect that your pet might have a maggot-infested wound or you see them maggots swirl take your pet to your vet ASAP.
