British skies may swarm with twice the current number of flies if temperatures carry on rising, experts warn.
Scientists at the University of Southampton (a member of RRF) are predicting the fly population is to soar by 97%, posing a widespread risk to human health. Dr Dave Goulson led the four-year study at a dozen landfill sites, which were plagued by flies every summer. He told BBC News Online: "A small increase in temperature gives whopping great increases in fly numbers."
Dr Goulson, a biological scientist, warns that a bigger fly population may lead to spiralling cases of food poisoning in humans. Food poisoning, normally not seen in winter, could happen all year round. He says warmer weather will also lead to large rises in other insect pests, including some never before seen in the UK.
The findings – based on research at landfill sites in Hampshire and the Midlands – come after UK wasp numbers rose to a 20-year high this summer. Dr Goulson told BBC News Online: "Some of the main food poisoning bugs are thought to be carried by flies, so more flies mean small epidemics could become much bigger. "Traditionally, the cold British winter killed off most insects and it took them until well into the spring to recover their numbers, but milder weather has seriously affected this cycle. "This means outbreaks of food poisoning, normally not seen in winter, could happen all year round.
Continental invasion
"We have already seen continental insects invading Britain, such as termites and a new species of wasp.
"If temperatures continue to rise, it is very likely that we will start to see insects like the Colorado potato beetle, which wipe out potato and bean crops on mainland Europe." Dr Goulson says fly numbers could be cut by composting waste like kitchen scraps and garden clippings, instead of sending it to landfill, where it provides rich food for flies.
He added: "Unfortunately flies have become resistant to most insecticides, but simple old fashioned things like fly paper and keeping food covered still do the job."

Egypt reviews Red Sea waste management system – Dailynewsegypt
Egypt’s Minister of Local Development and Environment, Manal Awad, and Red Sea Governor Walid El-Barqi held an extensive meeting to review the performance of the governorate’s waste management system and discuss measures to improve environmental services and operational efficiency. The meeting, held during Awad’s visit to the Red Sea Governorate to mark World Environment Day, focused on assessing current challenges facing waste collection, sorting, recycling and disposal operations, as well as identifying priority actions to strengthen the system’s performance. Awad stressed that the government places significant importance on developing an integrated waste management system in the Red Sea Governorate, given its strategic importance as one of Egypt’s leading tourism destinations. She emphasized the need to comply with environmental and technical standards governing sanitary landfills, waste treatment facilities and environmentally sound disposal practices. During the meeting, officials reviewed the current status of waste management operations in Hurghada, including collection, transportation, sorting, recycling and final disposal activities. Discussions also covered the infrastructure upgrades required to improve system efficiency and ensure the proper operation of sanitary landfill facilities. Yasser Abdullah, head of Egypt’s Waste Management Regulatory Authority, presented updates on temporary waste collection and sorting sites and outlined measures to strengthen operational management and oversight. He highlighted the importance of improving monitoring mechanisms for waste handling activities and maximizing the recovery of recyclable materials while reducing informal and unregulated practices.
