Invisible flies, often called no-see-ums or biting midges, can ruin outdoor relaxation. Fortunately, certain outdoor furniture materials and designs naturally deter these pests. Cedar and teak wood, for example, contain natural oils that repel insects. Opting for furniture with tight weaves or mesh screens can also block flies from settling. Additionally, incorporating citronella-infused cushions or planting lavender nearby enhances protection. These eco-friendly solutions keep your patio or garden fly-free without harsh chemicals. For lasting results, combine smart furniture choices with strategic plantings to create a naturally pest-resistant outdoor oasis.
