Insecticide-based control measures (e.g. indoor spraying with insecticides, bed nets) are the principal ways to kill mosquitoes that bite indoors. However, after prolonged exposure to an insecticide over several generations, mosquito populations, like those of other insects, may evolve resistance, a capacity to survive contact with an insecticide. Since mosquitoes can have many generations per year, high levels of resistance can evolve very quickly. Resistance of mosquitoes to some insecticides has been documented with just within a few years after the insecticides were introduced. Over 125 mosquito species have documented resistance to one or more insecticides. The evolution of resistance to insecticides used for indoor residual spraying was a major impediment during the Global Malaria Eradication Campaign. Judicious use of insecticides for mosquito control can limit the evolution and spread of resistance. However, use of insecticides in agriculture has often been implicated as contributing to resistance in mosquito populations. Detection of evolving resistance in mosquito populations is possible, so control programs are well advised to conduct surveillance for this potential problem.[9]. In Malawi and other places, a shrub known as mpungabwi (Ocimum americanum) is used to repel mosquitoes.[16]
