10.11.1 Correct IRS procedures
- Make sure that the house is ready for spraying (as explained in Section 10.10).
- The outside of the front door is the first surface to be sprayed.
- After entering the house, close the front door and spray it on the inside, including all frames of the door.
- Start the next swathe of spraying from the bottom corner of the wall to the right of the front door and proceed clockwise as shown in Figure 10.4. Spray all edges and corners of windows, as well as all niches and cracks where mosquitoes might rest.
- The backs, undersides and interiors of all cupboards, boxes, ovens, calendars, pictures, stools, beds, chairs and tables must be sprayed.
- Other household areas, i.e., kitchen, store, stable and latrine, should be sprayed next.
- After spraying, a final inspection is made by the spray operator to see that no surfaces on which mosquitoes might find a sheltered resting place remain unsprayed.
- Following inspection by you, the spray operator is assigned to another house.
- After spraying, the spray operator must tell each householder:
- Not to enter the house for 30 minutes.
- Not to re-plaster, mud-wash or white-wash inside the house for six months.
- The spraying is to control malaria vector species, not bed bugs, fleas, etc.
- To clean the floor and bury or burn the dirt, which is contaminated with insecticide.
