What is the situation with chitras on AC and other outer cays? My wife and I enjoy the tropics but she seems particularly sensitive to the chitra bites. She ends up with a 3-day bite mark that itches enough to keep her awake. We've experineced them around Dangriga and the Caribbean coast of Panama but not much on "Water Cay" east of Hopkins.

Any hints on where to go to avoid them but still get in on the ocean fun?
