[citation needed] Although they are considered harmless, some cases of myiasis caused by the larvae of this insect are reported in the literature, at the nasal, intestinal and urinary levels but are often associated with very poor sanitary conditions and bad hygiene habits.
[8][9][10] Protected by the extremely fine water-repellent hairs covering their bodies, adults and larvae are difficult to drown,[11] and are not affected by contact with most water-borne toxins such as bleach.
Boiling water has little or no effect on the adults for the same reason, and even the eggs are highly resistant to both chemical or thermal assault.
[citation needed] Suspect drains can be identified by placing a glass jar or taping a clear plastic bag over them, and periodically checking for adult flies.
[11] Partially covering the drain opening with sticky adhesive tape is another method used to identify breeding sources.
[13] Thorough mechanical cleaning of drains will remove the larval food source, and is the most effective control measure.
