As summer brings high temperatures to the UK, household pests become more active. Warmer weather accelerates breeding, while humidity and open windows make it easier for pests to enter homes. Pest control statistics show a dramatic surge in pest activity during seasonal highs, with rodent presence increasing by over 30% and insect populations exploding in warmer spells.
Among the most bothersome and unsanitary household pests in summer are flies: houseflies, fruit flies, and drain flies. These insects pose serious hygiene risks by carrying bacteria such as E. coli, Salmonella, and Listeria from rubbish and drains onto fresh food, according to the Express.
DIY fly trap method
Home maintenance specialists at Howarth Timber explain: "Fruit flies thrive in warm kitchens where ripe fruit and organic waste are present, so prevention starts with removing anything that attracts them in the first place." They add: "Bins should be emptied frequently and kept tightly sealed, while sink drains also need attention as food waste build-up can quickly create breeding sites. Pouring boiling water down the drain regularly can help clear residue and reduce activity."
The specialists share a simple natural trap: "For any [flies] that do appear, a simple natural trap can be made using apple cider vinegar in a bowl covered with cling film and small holes to attract and trap the flies." A 350ml bottle of Aspall Apple Cyder Vinegar is available at Asda for £1.48, making it a cost-effective solution. They add: "Essential oils such as lemon or eucalyptus can also be used around kitchen surfaces to help deter them."
Pest control experts' variation
Pest control specialists at deBugged The Pest Control Blog echo the guidance with their own variation: "You can make your own with a jar, by adding apple cider vinegar (to attract fruit flies) and a few drops of washing-up liquid (to make them sink when they land)." They suggest adding a paper funnel to the top of the jar to make it harder for flies to escape, ideally using yellow paper which attracts fruit flies. "Replace the solution every two to three days. You can also buy yellow sticky-paper traps and small containers with funnels."
