Removal of all fly larvae, first cleaning, then removal of crusts and pus remains, followed by occlusive dressing with an ointment (e.g. Vaselinum alb., paraffin, pig fat, beeswax) over a few hours. Due to O2 deficiency, the larvae move out of their crypts. Afterwards, they are cleaned again and fly larvae are removed by light pressure or with a needle or tweezers. In case of failure, icing of the affected area with chlorethyl spray and removal of the larvae with a scalpel. In the case of single small granulomas, removal can be done by punch biopsy.

External therapy

After removal of all larvae, external antibiotic therapy with tetracycline-containing ointments (e.g. R250, Achromycin ointment), fusidic acid (e.g. fucidine ointment or cream), 2% clioquinol-containing topicals (e.g. R049, Linola-Sept).
