we also use the Thermo-cell with good results, and the OFF candle ones with the pads like the thermo-cell.
As far as spray-on repellant the best I have ever used Hands Down is a 50/50 mixture of Skin so soft and rubbing alchohol!
It keeps your skin soft and not sticky and is actually good for your skin unlike anything with Deet in it.
I spent more than 20 years in the Army and have used this mixture on 6 of the 7 continents and various islands with awesome results!
