Warmer conditions don’t just affect your energy bill. They can change the pest pressure around your facility.
Southern Africa is entering a summer period in which above-normal temperatures and below-normal rainfall are currently forecast across much of the country. The developing El Niño is expected to be an important influence on the 2026/27 summer climate.
For food facilities, manufacturers, warehouses, hospitality businesses, retailers and other commercial operations, changing environmental conditions can create another challenge:
Why should businesses be concerned?
Temperature influences insect development, activity and behaviour.
For food facilities in particular, warmer conditions can interact with the conditions already present inside a facility, including food availability, moisture, storage areas, equipment, drains, waste areas and incoming goods.
Research into pest management in food supply chains highlights that food facilities can provide relatively protected microclimates for insects, allowing pest populations to persist even when outdoor conditions fluctuate.
This means your facility cannot be considered separately from the environment around it.
Warmer conditions can create more opportunities for pests
Depending on the species and local conditions, increased temperatures can influence the activity and development of pests such as:
- Flies and other flying insects
- Cockroaches
- Ants
- Stored-product insects
- Rodents
For a food facility, the consequences can extend well beyond seeing a pest on the production floor.
Pests can contaminate products, packaging, equipment and surfaces. They can also move between external areas and internal production, storage or handling environments.
And the warmer the conditions become, the more important it is to understand where pest pressure is coming from and where pests are finding opportunities inside the facility.
Your facility may be providing the conditions pests need
A pest problem doesn’t necessarily mean your facility is dirty.
Pests can enter through deliveries, loading areas, doors, ventilation points, drains, cracks and other access points.
Once inside, they can exploit:
Food + water + shelter + suitable temperature = opportunity.
This is why pest management in a food facility cannot rely on simply spraying when a pest is seen.
A strong programme looks at the entire environment.
What does this mean for your pest management programme?
A hotter summer is a good reason to review your existing pest management programme before pest pressure increases.
Look at:
Entry points
Are doors, windows and other access points properly controlled?
Receiving areas
Could incoming goods, packaging or deliveries introduce pests?
Waste management
Are waste areas creating food, moisture or harbourage opportunities?
Drains and wet areas
Could moisture and organic material be supporting pest activity?
Stored products
Are storage conditions allowing stored-product pests to develop unnoticed?
Monitoring data
Are pest trends being reviewed, or are records simply being filed away?
Corrective actions
When activity is detected, is the underlying cause being investigated and addressed?
These questions become particularly important when environmental conditions are putting additional pressure on pest populations.
Professional pest control is about more than treatment
Professional pest management provides a structured approach to identifying, monitoring and controlling pest activity.
Rather than relying solely on reactive treatments, a professional programme can incorporate:
Inspection: Identifying harbourage, entry points and contributing conditions.
Monitoring: Using appropriate monitoring devices and reviewing activity over time.
Trend analysis: Identifying changes in pest activity before they become a larger problem.
Corrective action: Addressing environmental and structural conditions contributing to pest pressure.
Targeted treatment: Applying appropriate control measures based on the pest and the situation.
Documentation: Maintaining the records needed to demonstrate that pest management is being actively monitored and managed.
For food facilities, this forms an important part of maintaining a controlled and hygienic environment.
Don’t wait for the first pest sighting
The arrival of summer shouldn’t be the trigger for starting your pest management programme.
It should be the trigger for asking whether your existing programme is prepared for the conditions ahead.
A hotter season can expose weaknesses that weren’t obvious during cooler months.
The goal is not simply to eliminate the pest you happen to see.
It is to understand why the pest is there, where it is coming from, what is attracting it and how to prevent the problem from becoming established.
With professional pest management, businesses can take a proactive approach to the increased environmental pressures that summer may bring.
The weather may be outside your control. Your pest management strategy isn’t.
