These incense repellent sticks ($15 for a box of 12) are soothing, calming, and will give your backyard a serene vibe while also getting rid of insects. Similar to a citronella candle but in incense form, these sticks are a fun alternative that also give a warm, inviting feel to the patio. Laced with citronella, lemongrass, and rosemary essential oils, these incense sticks are DEET-free and can last for up to three hours.
