How many times a mosquito will bite the same person depends on whether mosquito is interrupted during feeding, as female mosquitoes that bite to get blood for egg development will typically bite once and then leave to digest blood and lay eggs, but if interrupted before full, they may bite same person again within short time to complete meal. Female mosquitoes need blood meal to develop eggs, and they will land, pierce skin, inject saliva, and feed until engorged, which takes few minutes, and then fly away, and they will not bite again until they have digested blood and developed eggs, which takes few days. However, if you swat or move and interrupt feeding before she is full, same mosquito may bite again immediately nearby to finish meal, so you may get multiple bites from same mosquito in same encounter. Also, if many mosquitoes are present, you may get many bites from different mosquitoes that appear as same mosquito biting repeatedly. Mosquitoes are not like wasps that sting multiple times out of defense, they bite for blood, and they prefer to feed completely once. So a single mosquito will usually bite same person once per blood meal, but may bite again if interrupted, and you can get many bites in one night from many mosquitoes. To reduce bites, eliminate standing water where they breed, use repellents containing DEET, picaridin, or oil of lemon eucalyptus, wear long sleeves at dusk and dawn, and use screens and fans outdoors as mosquitoes are weak fliers.
