These picks are safe for kids, pets, and the planet when used properly.
1. Allethrin Lamps
Allethrin lamps (like ThermaCELL, $30, and OFF!, $10) use a butane cartridge or flame, respectively, to activate the chemical repellent.
Pros: Typically, 93% to 99% of mosquitoes and sand flies steer clear of a 15-foot area for up to four hours on each refill mat. Lamps are attractive and unobtrusive.
Cons: Refills cost $5 to $6. Keep an eye on the flame version, especially around children and pets.
2. Geraniol Candles
Geraniol candles (like those from Koolatron, $10) disperse a plant-derived repelling scent.
Pros: Five times better than citronella, it repels more than 80% of mosquitoes and 70% of sand flies for up to 10 feet. A one-pound candle lasts 50 hours.
Cons: With candles, the open flame poses a risk. While most people find the smell pleasant, some won't like it.
