In addition to the Dr. T's, we found this online:
Effective Mosquito Repellent for Outdoor Areas | Thermacell
We bought the small, outdoor version before investing in the "pretty" lantern version. We used it last weekend, and it worked very well! It "creates a 15 x 15-foot zone of bug-free comfort", according to the manufacturer and we found that to be very accurate. We will definitely be buying the lantern version for our outdoor dining table. The manufacturer's website says that it is "virtually odor free". We did notice odor if we were too close to it, so just know that if you're sensitive to smells you'll want to keep it at a little bit of a distance.
