Protecting clothing and gear, not just the skin, is how uniform protection is achieved. Permethrin is applied to fabric so insects encounter the treated material directly; it provides both repellent and insecticidal action on contact, and it stays effective through many washes. That makes it the go-to choice for treated uniforms.

In contrast, DEET and picaridin are designed mainly for skin application, protecting exposed skin by creating a vapor/chemical barrier. Pyrethrin is an older, fabric- or surface-directed insecticide, but it doesn’t offer the same durable, long-lasting protection on clothing as permethrin and degrades more quickly with sunlight and laundering.
