Hot Weather, Hotter Problems: Osaka Expo’s Battle with Summer Insects Unveiled!
Recently, a “plague of insects” has appeared in Osaka, Japan, with a large number of flying insects swarming around local landmarks and rooftops, even spreading to hotels, guesthouses, and convenience stores. This occurred during the World Expo, causing significant distress to both tourists and local residents.
While Japan is known for its cleanliness, the proliferation of mosquitoes and insects worsens with the arrival of summer. Similarly, Hong Kong, located in a subtropical region, also needs to address the issue of summer pests. With frequent rainfall and stifling heat, these pests may already be lurking in homes. This situation is not just a hygiene issue; especially in the hot summer weather, pests are more likely to move indoors from their natural habitats to seek relief from the heat.
The experts at Johnson Group provide insights into common summer pests such as cockroaches, ants, flying ants, and more, offering Professional Pest Control Advice to help you prepare in advance.

Summer Common Pests
Cockroaches
Cockroaches are among the most feared pests! Summer is their peak season, as in high temperatures, they crawl into homes through sewers and drains. They can quickly multiply indoors, with a female cockroach laying dozens of eggs in a short time. Without timely control, the entire house can soon become a hotspot for roaches. Additionally, recent studies suggest that common insecticides and cockroach sprays may not be effective for household pests. Furthermore, using pesticides containing pyrethroids not only fails to address the root cause but long-term exposure can impact health, leading to respiratory diseases, neurological damage, and even an increased risk of cancer, especially harmful to pregnant women and children.

Ants
Despite their small size, ants‘ communal behavior makes them highly destructive household pests. Their nests are usually in the soil, making them very sensitive to temperature and humidity changes. With Hong Kong’s prolonged summer temperatures exceeding 30 degrees Celsius and the humid weather, ant colonies are forced to seek cooler, stable environments, often infiltrating areas like kitchens, bathrooms, wall crevices, and even inside appliances in homes. While a few scattered ants may not have a significant impact, once they nest in a house, the problem could escalate to hundreds of ants, posing unimaginable consequences.

Flying Ants / Termites
Flying ants are actually the reproductive caste of termites, often signaling a more severe termite crisis. During the rainy season or humid evenings, these flying ants with transparent wings emerge in swarms for mating. After reproducing, they shed their wings and infiltrate cracks in buildings, wooden structures, or damp corners to establish new termite nests. Termites, feeding on cellulose, silently hollow out wooden floors, furniture, books, and even the structural beams of buildings. Early signs may include small wood shavings or mud-like trails, but by the time visible damage is noticed, it may already be irreversible. Moreover, termite nests may be hidden underground or within walls, posing a serious threat to the entire structure of a house if not professionally handled.
