Professional cleaners say fruit flies are among the most common summer nuisances in Finnish homes, especially in late summer and early autumn. The flies can spoil food by spreading yeast and bacteria and laying eggs in edible items.
According to Reetta Alastalo, CEO of Koti puhtaaksi Oy, the most effective trap for fruit flies involves ingredients found in most kitchens.
“Fill a cup halfway with water, then add a small amount of washing-up liquid, one tablespoon of vinegar, and less than a teaspoon of honey. Stir gently. The detergent removes surface tension so that flies sink into the liquid,” she explained.
She advised that regular kitchen cleaning is equally important. Worktops and sinks should be kept clean, and perishable foods stored in closed containers or in the fridge. Overripe or bruised fruit should be removed from bowls to avoid attracting flies.
Fruit flies are especially drawn to bio-waste, said Sandra Todorovic, a cleaning expert at Freska, and Emma Ketopelto, cleaning trainer at Kotiring. Both stressed that organic waste should be kept in closed containers and emptied every two to three days.
“Bio-waste is a major source of fruit flies and other pests. Keeping it sealed or removing it often prevents infestations,” Todorovic said.
“Ventilating the home also helps keep pests away,” she added.
Ketopelto suggested an alternative trap using fruit instead of liquid.
“I use banana slices in a bowl covered with pierced cling film. The flies crawl in but can’t escape. Then I press them against the bowl’s edge,” she said.
Beyond fruit flies, Ketopelto warned that many other household pests can be managed with basic cleaning habits.
“Regular vacuuming and cleaning inside kitchen cabinets reduce habitats for pests. Pouring boiling water down drains helps drive out silverfish. Always empty the vacuum cleaner bag afterwards,” she said.
Ants, another common summer problem, can be discouraged using salt instead of chemical pesticides.
“If you find ants inside, identify their trail and sprinkle salt along it. They will try to avoid it and hopefully stay outside. Salt is safer for homes with children than toxic sprays,” Ketopelto said.
All experts agreed that cleanliness is the most effective defence against household pests.
