Catering businesses also get everything out of the closet to get the critters away. Tina Slabbinck, Bistro La Gare: “I hung a fly curtain, got fly swamps and mills, and in the evening I spray with product. But the day after they are just back there.”

Also in café De Kroon a little further on they suffer from unwanted visitors. Geert Cappelle, Café De Kroon: “They are dead and a few hours later you have a thousand in. Every morning we find a completely dirt fly flying.”

And it turns out, the entire center of Gistel is bothered by it. But the cause of the fly plague is not immediately clear.
