Are There Many Insects In Guatemala?
Guatemala is a tropical country and does have bugs. It is, however, not as bad as you might think, and with the proper amount of protection you will be fine.
Mosquitos are found here, and are most abundant during the rainy season. If you'll be traveling in Guatemala during this itme of the year be sure to take precautions to protect yourself from mosquitos, since they can transmit malaria. A good way to do so is by using insect repellent with DEET and wearing long-sleeved shirts and pants.
Sand fleas are found in some coastal areas, particularily along the Caribbean Coast. You might not even feel them while they are biting, but you'll have welts around your ankles later on. They tend to be worst during the dry months, when oceanic breezes calm down and allow them to flourish. If you'll be visiting beaches in Guatemala, bring pants, long-sleeved shirts, a hat, and insect repellent.
