Insect/Ant bites

I just visited Las Brisas in Ixtapa (for the 7th consecutive year). Once again, I have suffered a multitude of bite from unseen insects. I suspect they are small ants - but? How can I keep them away from my suite and me? How can I best treat the bites? They itch and sting for days. Thanks for any and all suggestions.

Simple, STOP SCRATCHING. If you must touch it, smack it, rub it, but DO NOT SCRATCH. Itch is gone in 5 minutes.

What bit you were midges, no-see-ums. We call them jejenes.

When outdoors near the beach in the late afternoon and early evening, splash a little AUTAN on your exposed skin.
