The answer to 'what attracts mosquito' is that mosquitoes are attracted to certain factors, including standing water, warm body temperatures, and the carbon dioxide we exhale. Mosquitoes are drawn to these elements because they provide the ideal conditions for them to breed and feed.
Mosquitoes lay their eggs in stagnant water, so any source of standing water around your home, such as birdbaths, gutters, or pet bowls, can attract them. They are also attracted to the warmth and carbon dioxide we emit, as these signals indicate a potential host for a blood meal. Mosquitoes use their keen sense of smell to detect these attractants from a distance.
