Buffalo gnats, also known as black flies, can ruin outdoor relaxation. Fortunately, certain outdoor furniture materials and designs naturally deter these pests. Cedar and teak wood contain natural oils that repel insects, making them excellent choices for gnat-resistant furniture. Metal furniture, especially aluminum, is less attractive to gnats as it doesn’t retain moisture like wood or wicker. Opt for light-colored fabrics, as dark colors attract these insects. Incorporating citronella-infused cushions or mosquito netting around seating areas adds an extra layer of protection. For maximum effectiveness, place furniture in breezy, sunny spots, as gnats avoid windy and well-lit areas. By selecting the right materials and strategic placement, you can enjoy your outdoor space without constant swatting.
