When a heatwave hits the UK, our daily routines change completely. We fling windows open, turn up the air conditioning, and look for any way to stay cool. But we are not the only ones reacting to the rising temperatures.
Hot weather changes how insects and rodents behave.
It is important to understand what can happen to your property during a hot spell so that you know how to keep your property protected.
Insects are cold blooded, which means their activity levels and energy are tied directly to the temperature around them. When we experience a heatwave, their internal metabolism spikes. This means they eat more, move faster, and reproduce much quicker than they do during a standard British summer.
Flies and cockroaches can see their life cycles speed up significantly, meaning eggs hatch faster and populations can grow in a very short period of time. Warm weather also extends the natural breeding season for rodents, which can lead to larger numbers looking for food and shelter as the seasons change.
Pests need to stay hydrated to survive. When outdoor puddles, morning dew, and natural ditches dry up, pests such as rats, mice, ants, and cockroaches are forced to look for alternative water sources.
The lack of natural water sources can drive them straight into London’s residential and commercial buildings. They are highly skilled at tracking down hidden moisture, whether that is condensation dripping from an air conditioning unit, a small leak under a kitchen sink, or standing water inside a floor drain. Cool, dark basements and humid utility rooms also provide a perfect hiding place.
When temperatures rise it can cause building materials to expand slightly, which can widen tiny micro gaps around window frames, external brickwork, and skirting boards. Ants foraging for food can easily exploit these new entry points to find their way into your kitchen, storeroom, or commercial kitchen.
Foraging rats and mice can also use these ground level openings to escape the midday sun. This is a frequent challenge in dense urban areas like London, where shared walls and older infrastructure make pest movement easier.
Warmer temperatures can cause wasp nests to grow larger and reach their peak sizes much quicker than usual. The wasp larvae can develop faster, meaning bigger colony numbers in less time. With more worker wasps foraging for resources to feed the growing nest, your outdoor space can quickly see an increase in activity.
In tandem, the hot weather accelerates the decomposition of organic waste. Bins left out in the direct sun release strong, far-reaching odours that are highly attractive to pests. Wasps will aggressively hunt for your sugary food and waste during the summer months, while an unsealed or overflowing bin store provides an easy, high-calorie meal for rodents right on your doorstep.
You can protect your property by making a few simple adjustments to your daily routine. First, focus on your waste management. Keep all internal and external bin lids tightly sealed, rinse out food containers before recycling, and try to move outdoor waste storage away from your main entry doors.
Next, remove any easy water sources. Fix dripping taps, clear out floor drains, and ensure areas with high humidity are well ventilated to disrupt the damp conditions that pests seek. Finally, consider installing professional mesh screens on windows that you need to leave open for airflow. This allows you to keep your property cool without leaving it vulnerable to seasonal visitors.
