best bug repellent candles

Outdoor citronella candles come in single-wick and multi-wick formats. Common options listed include single-wick, 3-wick, and 5-wick candles.

Product listings recommend these candles for outdoor tabletop, deck, and patio use and for gatherings such as parties and camping—generally to provide area protection where people gather outdoors.

Burn time depends on the format: tea lights list about 5 hours, while jar and bucket candles commonly list burn times from roughly 25 up to 50 hours, depending on size.

The active ingredient is listed as citronella oil. Wax bases include paraffin and hydrogenated soybean oil. Containers are commonly metal/tinplate or ceramic. Wick types noted include non-cored constructions and, in at least one jar, cotton wicks.

Several listings specify citronella oil at a 3% concentration in the ingredient list. Not all listings state a concentration, so check the specific product label or description for the exact amount.

Tea-light citronella candles are sold as small (~0.35 oz) tealights in multi-count packs (example: an 18-pack). They’re described for scattering around outdoor spaces or using in tea-light holders; listed burn time for these tealights is about 5 hours.
