  • Info Indoor residual spraying or IRS is the process of spraying the inside of dwellings with an insecticide to kill mosquitoes that spread malaria. more...
  • Malaria control activities included indoor residual spraying, improved diagnosis and case management, and capacity building to contain future outbreaks.
  • Indoor residual spraying as vector control measures for the prevention of malaria epidemics has continued to be put into operation.
  • In recent years, additional questions on indoor residual spraying, as well as biomarker testing for anemia and malaria have been conducted.
  • Indoor residual spraying is the spraying of insecticides on the walls inside a home.
  • Another alternative is the use of Indoor residual spraying of insecticides.
  • The main objectives of the project were to measure the effects of indoor residual spraying and mass drug administration and to construct and test a mathematical model of malaria transmission.
  • This intervention, called indoor residual spraying (IRS), greatly reduces environmental damage.
  • Control measures that rely on insecticides (e.g. indoor residual spraying) may actually impact malaria transmission more through their effect on adult longevity than through their effect on the population of adult mosquitoes.
  • The first pesticide used for indoor residual spraying was DDT.
  • The evolution of resistance to insecticides used for indoor residual spraying was a major impediment during the Global Malaria Eradication Campaign.
  • This form of mosquito repellent is slowly replacing indoor residual spraying, which is considered to have high levels of toxicity by WHO (World Health Organization).
  • Insecticide-treated mosquito nets (ITNs) and indoor residual spraying (IRS) have been shown to be highly effective in preventing malaria among children in areas where malaria is common.
  • In order to see results from the usage of indoor residual spraying programs 80% of the towns homes need to be sprayed and the continual application of insecticide needs to be constant in order to suppress certain species densities which are immune to the insecticide.
  • After the link to mosquitos and their parasites were identified in the early twentieth century, mosquito control measures such as widespread use of DDT, swamp drainage, covering or oiling the surface of open water sources, indoor residual spraying and use of insecticide treated nets was initiated.
  • Nevertheless, DDT is still manufactured and used, and one study had concluded that "DDT is still a viable insecticide in indoor residual spraying owing to its effectivity in well supervised spray operation and high excito-repellency factor."
  • Better access to ACTs is an essential part of the comprehensive package of interventions required to fight malaria that includes prevention (insecticide-treated nets, indoor residual spraying, other vector control techniques and in development of malaria vaccines) and treatments for severe malaria.
  • In Liberia, for example, the United States had large military operations during the war and the U.S. Public Health Service began the use of DDT for indoor residual spraying (IRS) and as a larvicide, with the goal of controlling malaria in Monrovia, the Liberian capital.
