I never had a problem with mosquitos but my wife and I both had bug bites. She had a lot on her leg and I had a couple on my shoulder. I really had no idea what they were but when we got back I read there are chiggers in aruba. Now we did a lot of hicking, I don't think we picked them up on the beach. If your concerned but don't want the smell of bug spray you could try Avon "skin so soft".
