Devices and methods for controlling insects are generally described. Typically, the devices include a fiber web comprising a plurality of glass fibers or other substrate made of non-absorptive material impregnated or otherwise loaded with an insect control composition comprising an active insecticidal species (e.g., a pyrethroid such as Transfluthrin). The devices provide protection against arthropods or other insects over prolonged periods of time. Such devices may be lightweight, low-cost, reusable, and disposable, and can be used for both indoor and outdoor purposes.
