Depending on your pest issue, there are a few ways to use beer to repel bugs from you and your yard. Like many of your guests, wasps and flies enjoy a brewski now and again. Set a few shallow bowls along the perimeter of your gathering area and fill them with beer, either fresh or flat. Rather than buzzing around you and your hors d’oeuvres, these flying pests will relax by the frothy beer ponds you’ve laid out.
Another innovative way to use beer to deter pests in your yard is to create your own insect repellent to spray around the yard before you plan to lounge there. You’ll need a flat beer, Epsom salt, mouthwash, and dry yeast. In a spray bottle, add 1 cup of each of the first three ingredients and shake to mix. Then add half a packet of dry yeast and shake the bottle until the salt and yeast dissolve. Spray the contents along the perimeter of your yard or gathering place as needed to keep pests at bay.
