When tortoises develop even minor wounds, they can be susceptible to a condition known as myiasis, or fly strike. This is where flies lay their eggs in the open wound. Maggots then hatch, often eating or causing further injury to the tortoise. Tortoises with fly strike can become very lethargic or very agitated. A foul smell may also emanate from the wound site. Prevent fly strike by keeping wounded tortoises indoors. Ongoing fly strike infestations can be treated by removing the maggots and thoroughly cleaning the area. A veterinarian should then be consulted. They can prescribe antibiotics or further treatment if they are needed.
