Understanding the APVMA Permit to Treat Mange
WPSA is the permit holder of APVMA Permit PER90094, which allows for the use of up to 4 mL per kg body weight, with a maximum of 100 mL per treatment on an adult wombat.
Despite the success of this treatment program, there are still misunderstandings within the treatment community about how and why it works so effectively. Anyone who has used the permit correctly knows just how rapidly mange-affected wombats can improve, with relief often noted within 24 hrs.
So why is it so effective?
There are two key factors:
1. Cydectin does not work as a systemic treatment.
It does not pe*****te through the skin and circulate in the bloodstream. Instead, it remains on the surface of the skin where it is needed.
2. Mange mites live only in the epidermis.
The mites inhabit the epidermis, the thin outer layer of skin that contains no blood vessels. They do not burrow into the deeper dermis where blood vessels are present.
These two factors work together to make the treatment highly effective. When up to 100 mL of Cydectin is applied along the wombat's back, the vegetable oil carrier helps distribute the product across the skin surface, allowing immediate contact with the mites.
Cydectin is effective against all active life stages of the mite—from larvae through to adults—but it does not kill the eggs.
In very mild cases of mange, if all female mites are eliminated during the first treatment, the final eggs laid will hatch within approximately three days. If sufficient Cydectin remains on the skin surface, these newly hatched mites will also be killed before they can reproduce.
However, in moderate to severe cases, the number of mites present is much higher. Multiple treatments are therefore required 5 to 7 days apart up to 5 treatments because it is impossible to determine how many female mites may survive after any single treatment.
There is another important factor in successful recovery: minimising stress.
A wombat suffering from mange is already under significant physiological strain. For this reason, mange-affected wombats should not be captured, handled, netted, chased, or otherwise subjected to unnecessary stress. The additional burden placed on an already compromised animal can hinder recovery.
