Mosquitoes pose a health risk due to their ability to transmit diseases like West Nile virus and Zika virus. Individuals spending time outdoors, especially during dawn and dusk when mosquitoes are most active, are at higher risk of being bitten. Children, the elderly, and those with compromised immune systems are particularly vulnerable to mosquito-borne illnesses. Additionally, areas with standing water, such as ponds, birdbaths, and clogged gutters, are more likely to experience higher mosquito activity, increasing the risk of bites and disease transmission.
