When to Start Mosquito Control Before the Rains Begin

Mosquito numbers explode once water collects. Starting early keeps them down.

Begin before the first showers.

The short answer

Start a few weeks before the rains by removing stagnant water, cleaning gutters and tanks, covering containers, fixing leaks and draining AC trays. Consider professional larvicide and adult-control programmes in high-risk areas. Continue through the monsoon and a few weeks after.

Pre-rain steps

1. Clear gutters, drains and terraces.
2. Clean and cover tanks.
3. Empty pots, buckets and discarded containers.
4. Fix leaks.
5. Fit screens.

Through the season

• Weekly water checks.
• Repeat cleaning after each heavy spell.
• Professional service where needed.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
