    "headline": "European Heatwave Boosts Bed Bug Populations, Entomologist Says",
    "dek": "An entomologist warns that Europe's record-breaking heatwave is increasing bed bug numbers.",
    "prose": "Richard Nailor, an entomologist, stated that prolonged periods of warm weather, such as the anomalous heat in Europe this year, increase the population of bed bugs. [^1]\n\nA tourist named A, traveling with his daughter, checked into a hotel in Haeundae, Busan, on the evening of March 3, 2026, and discovered moving black insects on the bed at 3:00 AM. [^2]\n\nHotel staff denied the guest's claim, stating that a pest control inspection found no evidence of bed bugs, such as multiple insects or molting traces, and suggested the insects found were likely from other guests' luggage. [^3]\n\nIn the new room, the guest discovered black spots on the pillow and a small black insect crawling near the mattress, which he also identified as a bed bug using an AI app. [^4]\n\nThe guest demanded a refund for the accommodation, but the hotel refused, sending a text message stating that the room upgrade to a 400,000 KRW suite was sufficient compensation for the inconvenience. [^5]\n\nRichard Nailor explained that bed bugs live around beds because they feed on blood and are attracted to the carbon dioxide exhaled by humans. [^6]\n\nRichard Nailor told Daily Mail that the peak activity period for bed bugs occurs from spring to early autumn. [^7]\n\nExtreme heat returned to Western Europe in August, caused by an anticyclone centered over Germany. [^8]",
