Mmm okay so "bug infestation" it was only 3 ants in your room, exactly as you can see on the picture that you posted.... If telling customers NO we are not going to spray the rooms with a venemoun because it will kill not only the ants but butterflies, frogs, etc.. So yeap I don´t think Costa Rica is the right country for you to visit. If you don´t like ants, butterflies, monkeys, sloths, tucans, and be around a lot of nature and wildlife please follow this woman advise and don´t visit us because we are in the middle of the jungle on those are our neightboirs. I´m sorry those evil ants ruined your mood and make you hate your visit and everything around. Hope you feel pura vida.
