Disclosed herein is an article (such as an insect control pouch) to dispense a volatile active (such as an insect control agent). The pouch is formed from a single layer polymeric non-absorbing film. The pouch traps the active until use of the pouch is desired. When the pouch is opened the walls of the pouch serve as a substrate from which the active can readily passively evaporate. Methods of forming such pouches using heat sealing techniques, and methods of using such pouches, are also disclosed.

1. An article to dispense a volatile active, comprising a pouch having opposed walls made of a ploymeric material, each wall having only one layer, where said walls are releasably sealed together to define an interior cavity therebetween, the walls thus having inside surfaces within the pouch and outside, exposed surfaces, the walls and seals being impermeable to the active, an inside surface of at least one of said walls being coated with the vaporizable active, wherein no separable, active-bearing article is contained within the pouch.
