Pour in the vinegar and soap, shake everything up, and then place the obviously open bottle on the windowsill. The flies, or whatever other animals are attracted to them, will go to the window and fall inside,  unable to get out.

Otherwise, you can prepare another trap with 100 g of sugar, a litre of milk and 50 g of ground pepper. Cook everything on a low heat for at least ten minutes, then pour it into a deep plate. The flies will rest on top until they stick.

But it doesn’t end here, because with the same ease and speed you can create a fantastic insecticide to use for cleaning  windowsills or large windows.

Here’s how to prepare it: macerate fresh mint leaves in a jar with vinegar inside and leave them to macerate for 7 days. Once the required time has passed, pour the solution into a bottle, preferably with a spray bottle, and spray it onto the glass.

Thanks to the solution, not only will your windows become clean, clear and shiny thanks to the use of vinegar, but it will also keep flies and all other insects away from your house for a long time. When the effect of the napkin with lemon peels and window liquid starts to fade, you can do it all over again.
