FAQ
Frequently Asked Questions
The botfly does not bite in the typical sense. The danger comes from its larva (maggot) living under the host's skin, which can lead to a secondary bacterial infection (myiasis) if not properly removed.
Yes, but species vary. The UK has species like the sheep botfly (Oestrus ovis). The Americas have species like the human botfly (Dermatobia hominis) in Central and South America, and rodent botflies (Cuterebra) in North America.
Removal should be done by a medical professional. Methods include surgical extraction, applying a substance like petroleum jelly to suffocate the larva and force it to surface, or using precise tweezers after local anesthesia.
The key difference is reproductive strategy. Most flies lay eggs on decaying matter or food. Female botflies attach eggs directly to a host (or a vector like a mosquito), and the hatched larvae burrow into the host's tissue to develop, making them obligate parasites.
