For trips to buggy areas, we pre-treat our own clothes [using spray-on permethrin](https://www.sawyer.com/products/permethrin-fabric-treatment), which lasts about 6 washings or 60 days. You can also send away your clothes to [Insect Shield for professional treatment](https://www.insectshield.com/pages/insect-shield-your-clothes), which is intended to last for a garment’s expected lifespan. For spray-on bug spray, we prefer picaridin insect repellent over DEET, as its not greasy, doesn't ruin fabrics, and is odorless, while being just as effective.
