Report Anti-Dengue, etc. Campaign in Chapala in Ajijic/Chapala/Guadalajara Posted 14 hours ago This makes no sense to me. Why, when we are entering our coldest period and seven months of drought would Chapala now begin a spraying program for mosquitoes throughout the municipality? The money would be better spent, and more effective in June. However, if they want to come and spray my gardens for grasshoppers they are more than welcome.
