The present disclosure is directed to insect-resistant fabrics or garments and methods for making the same. The insect-resistant fabrics or garments include an insect repelling composition containing a micellar system and optionally an insecticide composition. As an example, an insect-resistant fabric in accordance with the disclosure can include a base fabric (e.g., polyester) having been treated to include an insect repellant composition containing a micellar system. The micellar system may include one or more insect repelling agents (e.g., essential oils) contained within one or more micelles (e.g., saponins) in a first region of the fabric, and optionally an insecticide (e.g., permethrin) in second region of the base fabric. The inclusion of a micellar system in an insect repellant composition is shown herein to provide improved insect-resistant efficacy.
