Bask in the gentle glow of mosquito protection! Cutter Citro Guard Candles are made with real citronella oil to repel mosquitoes and other flying insects. This triple-wick, 20-ounce candle burns up to 40 hours, and the wide, stable base prevents tipping. To reduce the annoyance of mosquitoes, use one or more candles in still air. To maximize the repellent barrier, use several Cutter Citro Guard Candles to create a perimeter of protection against flying insects. Place the candles at least 18 inches apart on a heat-resistant surface away from anything flammable and out of reach of children or pets.
