Mosquito Coils, Sticks and Liquids: Indoor Air Concerns

Mosquito repellents are common in Indian homes, but they affect indoor air.

Use them carefully.

The short answer

Coils produce smoke and particles, while vaporisers release an insecticide. Use them only in ventilated rooms, away from people sleeping in a closed room, children, pregnant women and people with asthma. Consider nets, screens and removing standing water as alternatives.

Cautions

• Smoke from coils can irritate lungs.
• Avoid in closed bedrooms.
• Keep away from flammables.
• Keep out of reach of children.

Safer approach

1. Use screens and nets.
2. Remove standing water.
3. Use fans.
4. Use repellents as directed and with ventilation.

Sensitive people

People with asthma or allergies should be especially cautious. Ask a doctor.

When to call a professional

See a doctor if you develop breathing problems or irritation.
