It's rare things get so bad that we slap this on, but I always feel to good to have it.
We like Sawyer Controlled Release Insect Repellant sold at REI. It has no odor, is a nice lotion blend and is slow release for many hours. We used it extensivley in Thailand and it worked pretty well. It has 20% DEET, which is enough to keep West Nile at bay without destroying your brain cells.
We always pour it out of the bottle into a small 1 oz squeeze bottle, so we don't take too much.
Bug Repellant from REI for $4.95.
Container from REI for $1.
