Where to look
- Ant/cockroach activity near plumbing or irrigated areas
- Rodent activity around reliable food/water sources
- US mosquito habitat that persists despite drought, such as stored water containers

Pests During Drought Conditions
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 water-seeking behaviour, irrigation and changing outdoor pressure.

Season and weather can explain activity — they cannot identify the pest
Use timing to decide where to inspect, then require physical evidence before treatment. A seasonal pattern alone is not proof of an infestation or its size.
What makes the conclusion stronger
- Drought can alter pest movement but does not prove causation at one property
- Repeated association with water sources is useful evidence
- Local species and climate matter
PestDeck pathway
Inspect → identify → correct → monitor → escalate
- 1Record the location, date and physical evidence.
- 2Identify the pest or narrow the candidates before treatment.
- 3Correct the relevant access, food, water, shelter or habitat condition.
- 4Monitor the same locations and compare activity over time.
- 5Escalate when structural, health, wildlife or infestation risk justifies it.
Practical steps
What to do next
- Fix leaks and avoid unnecessary standing water
- Keep food/waste contained
- Identify pests before changing control solely because of weather
🇬🇧
United Kingdom
Use UK species, HSE guidance and local seasonal context.
🇺🇸
United States
Use regional species ranges, EPA labels and state/local guidance.
