When do female Anopheles mosquitoes bite?

  • biting time varies between species, so travellers should assume they are at risk of being bitten from dusk to dawn inclusive

  • biting of several major malaria vectors in Africa peaks at and just after midnight so protection in bed is especially important

    • however, in many parts of South America and South East Asia, the greatest risk from being bitten by malaria vectors is in the evening, before the population retires indoors

    • note though - as other species of mosquito for example those which transmit yellow fever, dengue fever and other arboviral infections, bite during the daytime, it is important to maintain bite precautions during daylight hours
