- General House Hygiene
- Sweep and dust the house and utilities daily to remove germ-harbouring dust; clean the kitchen occasionally with disinfectant.
- Keep the house well ventilated to let in sunlight, which kills bacteria and prevents droplet infection; open and air dark cupboards (hiding places for insects/rats).
- Use insecticide sprays for insect vectors; use camphor in cupboards/drawers to repel cockroaches; fill or spray cracks to kill insects, bedbugs and ticks hiding there.
