Treatment options

• Some larvae (e.g. Cordylobia) can be expelled by applying firm pressure around the lesion.6

• Surgically enlarge the area of infestation and remove the larvae with forceps. This method is often used for D. hominis, whose larvae have backward-pointing spikes that prevent easy removal. Damaging the larvae can release fly antigens that could trigger severe immune reaction.6,8,15

• Cover the pore containing the larvae with butter, mineral oil, or petrolatum. The larvae will crawl out of the pore to avoid suffocating.6,15

• Injection of Xylocaine underneath an infested nodule, to force the larvae out 6

• In cases of nasal myiasis, anesthetize the larvae with ether or chloroform. Block the nostrils with dry cottons for about 2 minutes before removing the larvae via forceps and nose-blowing.6

• For treating human wound myiasis by C. hominivorax: topical administration of 1% ivermectin in propylene glycol for 2 hours.8

• Systemic ivermectin can be used to treat extensive infestation by D. hominis.8

• Wound myiasis: wash the maggots away from the lesion.6
