The mosquitoes that spread malaria lay their eggs in standing water, even small amounts — old tyres, blocked gutters, discarded containers, or water stored in open buckets can all serve as breeding sites.
A simple weekly habit of walking around your home and emptying, covering, or turning over anything that collects water can meaningfully reduce the mosquito population nearby. Water storage containers used for drinking or washing should be tightly covered rather than left open.
Clearing standing vegetation and keeping grass cut short near the home removes resting spots for adult mosquitoes, while filling in or draining puddles after rain removes breeding grounds.
These habits work best as a shared effort — talk with neighbours about doing a clean-up together, since mosquitoes don't respect property lines and breeding sites just next door can still affect your household.
