Where to look
- Where activity moved before and after the weather change
- Water, shelter and food conditions changed by weather
- Entry points newly exposed by rain, wind or temperature shifts

Why Weather Changes Pest Activity
Season and weather can change pest activity, but they do not prove an infestation. Use the timing as context and confirm with evidence at the property. Focus on how heat, cold, rain, drought and storms alter pest movement and visibility.

Use the event or season to focus inspection — not to diagnose the pest
Season, weather, travel or building work can change pest activity and visibility. Treat that timing as a clue only: identify physical evidence, correct relevant access/food/water/shelter conditions, and monitor the same locations.
What makes the conclusion stronger
- Correlation with weather does not establish species or infestation size
- Repeated patterns across the same evidence points are more useful
- Local species biology and building conditions matter
PestDeck pathway
Inspect → identify → correct → monitor → escalate
- 1Record the location, date and physical evidence.
- 2Confirm the pest or narrow the candidates before control.
- 3Correct relevant access, food, water, shelter or habitat conditions.
- 4Monitor the same locations and compare activity over time.
- 5Review results and escalate or adjust only when evidence justifies it.
Practical steps
What to do next
- Record weather alongside evidence rather than assuming causation
- Correct standing water, leaks or damaged exclusion
- Identify the pest before changing control
