Explain three practical steps that students can take to reduce mosquito breeding in their neighbourhood. For each step, describe why it helps prevent mosquitoes from breeding.
Answer
1. Remove stagnant water sources like old tyres, flower pots, and clogged gutters – mosquitoes need standing water for eggs.
2. Cover water containers such as water storage drums and rain barrels – this blocks access for female mosquitoes to lay eggs.
3. Use fine mesh screens on windows and doors – it stops adult mosquitoes from entering houses and reduces chances of egg laying indoors.
Step-by-step solution
- Step 1: Identify standing water in neighbourhood (old tyres, flower pots, puddles). Explain that standing water is a breeding site for mosquitoes.
- Step 2: Remove or cover these sources. This eliminates the place where eggs can develop. Step 3: Encourage the community to clean drains and gutters regularly to prevent water accumulation. Step 4: Use fine mesh screens on windows and doors so adult mosquitoes cannot enter. This reduces the likelihood of eggs being laid indoors. Step 5: Summarise that by eliminating breeding sites and preventing mosquito entry, the population of mosquitoes decreases, reducing disease transmission.
