Seasonal Pest Calendar: What to Watch For Year-Round

Understanding seasonal pest patterns helps you stay proactive rather than reactive. Here's what to watch for throughout the year in Sri Lanka's tropical climate.

January – March (Northeast Monsoon Tail)

Watch for: Mosquitoes, termites, ants

• Post-monsoon moisture creates ideal breeding conditions for mosquitoes
• Termite swarms often occur after heavy rains
• Ants seek indoor food sources during wet weather

April – June (Inter-Monsoon / Pre-Southwest Monsoon)

Watch for: Cockroaches, flies, mosquitoes

• Rising temperatures increase cockroach activity
• Fly populations surge with warmer weather
• Dengue season intensifies — eliminate standing water

July – September (Southwest Monsoon)

Watch for: Rodents, termites, mosquitoes

• Rodents seek shelter indoors from monsoon rains
• Continued termite activity due to high moisture
• Peak mosquito breeding in waterlogged areas

October – December (Second Inter-Monsoon)

Watch for: Bed bugs, stored product pests, cockroaches

• Holiday travel increases bed bug risk
• Stored product pests can infest holiday food supplies
• Cockroach populations peak in warm, humid conditions
