Part 2/9:
Bed bugs feed on the blood of warm-blooded animals, including humans, and their bites can lead to itchy welts, insomnia, and discomfort. The rising concern is largely linked to increased international travel, which facilitates the spread of these pests across borders. Travelers are advised to inspect their luggage carefully and wash belongings in hot water (around 50°C) upon returning home to prevent accidental transportation.
While Singapore has not yet seen a major bed bug outbreak, experts suggest that its good sanitation practices have kept infestations at bay. However, the country still faces challenges from smaller pests like dust mites, which thrive in humid environments similar to Singapore's tropical climate.
