Insect/Ant bites

Thanks to all of you for sharing your experience and solutions. I truly appreciate your help. One thing I'm sure about is that it's not bed bugs. I've had experience with those critters and the bites I have been getting are located around my ankles and lower legs and nowhere else. The bite characteristics are most like those from ant bites, not those from bed bugs. I'm sure that it's not a Las Brisas bed bug issue. The bite reaction is much more akin to that resulting from a fire ant bite you might get in Texas.
Again, thanks for all your thoughts.
