I bought this at the grocery store and it works like a dream! I'm always studying outside on the patio and I was getting eaten alive by bugs. But this thing has helped so much. The smoke doesn't smell at all- but it does smoke a lot so some people might not like that.
The lantern was about $13, and the refills are $5 for 3 pads and tea lights.
Off! PowerPad Outdoor Lantern
Repels mosquitoes from an average size deck/patio
One tiny PowerPad® mat repels annoying mosquitoes from up to 15ft x 15ft – an average patio or deck. Compare that to just one sq. ft. from a citronella candle. Simply activate the pad by lighting the candle and enjoy proven protection from mosquitoes.
The Lantern is similar to the Lamp, but includes a convenient 4-foot pole so that you can place it anywhere in your yard.
Protects an area up to 15x further than citronella candles or buckets
The heat from the candle activates the repellent pad, releasing proven protection from mosquitoes. In fact, there’s more repelling power in one little pad than 15 citronella buckets combined!
Each candle + pad combo provides up to 4 full hours of protection. Each refill pack contains three pads and three candles, providing up to 12 total hours of repellency per pack.
Relightable! The candle and repellent pad are designed to work together. So if the candle is extinguished, simply relight the candle to reactivate the repellent pad. When not in use, please follow the proper storage instructions. Prolonged storage of repellent pads in outdoor conditions may decrease effectiveness.

The only downside is that the heat pads burn through pretty quickly. I may get 3 nights out of one- if I'm outside for 2-3 hours at a time.
