Bangalore Pest Calendar: What to Expect Month by Month

Bangalore's mild climate means pests are active all year, but the mix changes with the seasons. Planning around the calendar saves effort and money.

This is a general guide. Local conditions in your building and neighbourhood matter too.

The short answer

Roughly, summer brings flies, ants and heat-stressed rodents seeking water; the pre-monsoon and monsoon months bring mosquitoes, termite swarmers, cockroaches, silverfish and moisture-loving pests; the post-monsoon months are good for inspection and repairs; and winter is quieter but cockroaches, rodents and bed bugs stay active indoors. Use the calendar to time inspections and preventive steps.

Summer (roughly March to May)

• Flies and ants around food and waste.
• Rodents looking for water and shade.
• Good time to service water tanks and check roofs before the rains.

Pre-monsoon and monsoon (roughly June to September)

• Mosquito breeding rises with standing water.
• Termite swarmers after the first rains.
• Cockroaches, silverfish and moths in damp cupboards.
• Rodents and insects moving indoors from flooded burrows.

Post-monsoon (October to November)

• Inspect for damp, termite signs and wood damage.
• Repair leaks and seal gaps.
• Check balconies, terraces and drains.

Winter (December to February)

• Cockroaches, rodents and bed bugs still active indoors.
• A good time for planned treatments and repairs.

How to use this

Pick two or three checks per season and put them on your calendar. Preventing a problem is easier than treating it.

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.
