Traveling to Guatemala without insect repellent is a mistake most tourists only make once. The country harbors mosquitoes that transmit dengue, Zika, and chikungunya, especially in lowland areas like Petén, the Pacific coast, and the Caribbean. Even Lake Atitlán at 1,560m elevation has its own mosquitoes during the rainy season.
The good news: with the right repellent, mosquitoes stop being a problem. In this guide we compare the 4 best insect repellents for Guatemala and explain when to use DEET versus picaridin.
DEET vs Picaridin: Which Is Better for Guatemala?
| Ingredient | Effectiveness | Duration | On skin/clothing |
|---|---|---|---|
| DEET 98% | Very high | 8-12 hours | Both, but can damage plastics |
| Picaridin 20% | High | 6-8 hours | Both, does not damage materials |
General recommendation: Picaridin for daily use (gentler on skin, no strong odor). DEET 98% for high-risk areas (Petén, Puerto Barrios) or nighttime activities.

Is there dengue at Lake Atitlán?
Dengue risk at Atitlán exists but is lower than in coastal or lowland areas. At 1,560m, the cooler temperature reduces mosquito density. However, during the rainy season (May-October) repellent is recommended, especially at dawn and dusk.
Can I buy repellent in Guatemala?
Yes, Guatemalan pharmacies carry Raid and Off with DEET in 15-30% concentrations. For picaridin or 98% DEET, bring your own repellent from home — they're not easily found in small towns.
Does repellent also protect against Zika mosquitoes?
Yes. The Aedes aegypti mosquito (which transmits dengue, Zika, and chikungunya) is sensitive to picaridin and DEET. Protection against this daytime mosquito is especially important in warm areas of Guatemala.
