Only palce I've encountered any type of biting insects, around the pool and sand beaches. Seems them sand fleas or gnats, bite like he... and leave a very itchy bite. Mostly only on the lower leg, ankle part for us. Smear some ammonia on the bite takes the itch out but if we're going to be on a resort beach in the evening, we slather on some Avon bug juice.
Seems during the day, no critters, its just when the sun starts to set.
