WITH THIS TRICK THE INSECTS WILL NOT ENTER THE HOUSE EVEN WITH THE WINDOWS OPEN

Simply slice a lemon in half and stud it with cloves. Place these fragrant guardians near windows or doors to create a no-fly zone in your home.

For a more mobile solution, mix a spray using essential oils known for their insect-repelling properties. Combine 10 drops each of mint and eucalyptus oils with half a liter of water, and spray liberally around entry points. This minty mist will keep flies at bay.
