As the name suggests, IRS entails applying a residual insecticide to a home’s walls and other surfaces. The insecticide will kill any mosquitoes and other insects that come into touch with these surfaces for a number of months.
IRS does not actively shield individuals from mosquito bites. Instead, if mosquitoes linger on the surface where the spray was applied, they are typically killed after they have fed.
The campaign’s stated goal was not met, although it did manage to eradicate malaria in certain places and significantly lessen the burden of the disease in others. DDT’s negative environmental effects prompted the development of new, more expensive pesticides.
As the eradication campaign progressed, endemic nations that could not bear the financial burden were given responsibility for maintaining.
IRS, also known as indoor residual spraying, is the practice of spraying an insecticide inside of buildings to eradicate malaria-carrying mosquitoes.
Certain types of homes, those with walls constructed of porous materials like mud or wood but not plaster as in city homes, are sprayed with a diluted pesticide solution.
The spray repels or kills mosquitoes, stopping the spread of the disease. IRS was used as a malaria prevention technique in some nations. IRS has historically made use of a number of pesticides, the first and best-known of which is DDT.
The Global Indoor Residual Spraying (IRS) market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
An essential vector management strategy that can quickly lower malaria transmission is indoor residual spraying (IRS). It entails spraying a residual insecticide on the internal surfaces of walls and ceilings in housing structures where the pesticide may come into touch with malaria vectors.
The goal of this operational manual is to help public health officials, entomologists, and managers of malaria programs create, carry out, and sustain effective IRS programs.
To stop the spread of malaria, indoor residual spraying (IRS) and insecticide-treated nets (ITNs) are utilised. Insecticides are used in both interventions to eliminate biting and sleeping mosquitoes. Simply because two interventions can be more effective than one, including IRS with ITNs may help control malaria.
Additionally, IRS may enhance malaria prevention in areas where ITNs are ineffective due to pesticide resistance. Since they are safer than other pesticide classes when in prolonged contact with human skin, pyrethroid insecticides are the most common class of insecticide used for ITNs.
Despite the fact that many mosquito populations have evolved some resistance to pyrethroid insecticides, IRS can still be carried out using a larger variety of insecticides.
