One effective fruit fly trap recipe is to mix apple cider vinegar with a few drops of dish soap in a small bowl. The vinegar attracts the fruit flies while the dish soap breaks the surface tension, causing the flies to drown. Another option is to create a trap using a small jar filled with ripe fruit and a paper funnel inserted into the jar to trap the fruit flies inside. Additionally, placing a few drops of red wine in a jar covered with plastic wrap and poking small holes in the wrap can also attract and trap fruit flies. **

Birds often fly into windows because they see the reflection of the sky or trees in the glass, which they mistake for open space. This can happen especially during mating season when birds are more territorial and may perceive their reflection as a rival bird. Additionally, birds may not be able to see the glass as a barrier, especially if the window is clean and transparent. To prevent birds from flying into windows, it is recommended to use window decals or screens to make the glass more visible to them. **
