The citronella and cedar formula of TIKI® Brand Ready 2 Light® BiteFighter® Torch Fuel provides proven mosquito repellency*. The convenient, prefilled canister fits most TIKI® Brand torches and lasts up to 5 hours. Simply remove the cap, ensure 3/4 inch of wick shows at the top, place the canister in the torch, light and enjoy a fun backyard or patio experience with relaxing natural flame ambiance. When the canister is empty, dispose of and replace with a new TIKI® Brand Ready 2 Light® canister. TIKI® Brand Ready 2 Light® canisters are not refillable. *Based on studies using CO2-emitting mosquito traps which demonstrated over 50% reduction in captured mosquitoes compared to untreated controls. Use as directed. Efficacy may be affected by weather conditions, torch placement, and individual physical factors.
