The owner of a newly-acquired iguana should always have it checked for parasites by a vet right away. Ticks can also carry and transmit disease. Visible ticks walking around on your iguana, or more often, seen attached in skin folds or under scales.
Favorite spots are in the soft skin around the eyes armpits, and vent.
Treatment - One way to get rid of ticks is to cover them with petroleum jelly. This closes off the breathing holes that cover their bodies, and they suffocate, die, and fall off. Another method is to grasp the tick s body with a forceps, as close to its head as possible, and gently pull until it lets go. Do not pull abruptly or forcefully, because the body will likely break off from the head, killing the tick but leaving the mouthparts embedded in your iguana s skin. This can lead to infection.
