5 Insect Repellents to Keep Bugs at Bay
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.

3. Metofluthrin Diffuser
Metofluthrin diffuser (by OFF!, $8) uses a fan to disperse a chemical that fends off mosquitoes -- no flame needed.
Pros: On average, one disc gives 84% to 100% protection against mosquitoes for up to 12 hours.
Cons: It's not shown to work against biting insects other than mosquitoes. Refills cost $5.
4. BTI Briquettes
BTI briquettes (like those by Summit, $21.50 for 20) use a bacterium found in soil that kills mosquito larvae before they hatch.
Pros: After adding them to standing water (a pond or unused pool), mosquito population is cut more than 90% in 48 hours and up to 85% for 28 days.
Cons: While these will significantly reduce the mosquitoes that hatch, they don't repel any remaining ones: No guarantee the neighbor's bugs won't come to visit.

5. Garlic Liquids and Granules
Garlic liquids and granules (like Mosquito Barrier liquid, $22, and Dr. T's granules, $14) use garlic, a natural bug repellent.
Pros: More than 90% of mosquitoes stay away for up to one month after application to foliage. May also work against ticks, fleas, and blackflies.
Cons: The initial strong smell might offend sensitive guests. Also, the more pungent liquid formula requires dilution, which is a time-consuming process.
