Determining the "worst" countries for mosquitoes is complex, as it depends on factors like mosquito species present, prevalence of mosquito-borne diseases, and the sheer number of mosquitoes. However, several countries consistently rank highly in terms of mosquito populations and the diseases they transmit.
High Mosquito Populations and Endemic Species
Several sources point to Brazil, Indonesia, Malaysia, and Thailand as having the highest number of mosquito species. These countries also frequently appear on lists of countries with high mosquito populations. Australia, Indonesia, the Philippines, and Brazil are noted for having particularly high numbers of endemic mosquito species.

High Prevalence of Mosquito-Borne Diseases
While sheer mosquito numbers are significant, the impact of mosquitoes is heavily tied to disease transmission. The World Health Organization highlights that Africa, South America, and Asia bear the brunt of mosquito-borne diseases like malaria and Zika. This means that even if a country doesn't have the highest mosquito population, its high incidence of these diseases makes it a challenging place to live due to mosquito-related illnesses.

Regional Variations and Seasonal Impacts
Mosquito populations and activity fluctuate significantly based on location within a country and seasonal changes. For example, even within Europe, certain countries like Italy, Spain, Greece, and France, experience periods with substantial mosquito populations. Similarly, regions with significant Taiga/Tundra environments (Siberia, Scandinavia, Canada) can experience high mosquito densities during summer months.

Important Note: Data Limitations
The information available on mosquito populations is not always uniform across countries. Accurate mosquito population counts require extensive monitoring and surveillance efforts, which are not uniformly implemented globally. Therefore, the information provided above should be considered a general assessment, rather than a definitive ranking.
