Abstract:
1. A substrate for use in a volatile dispensing device that actively dispenses volatile material from the substrate, the volatile dispensing device having a slot through which the substrate can be inserted to load the substrate into the volatile dispensing device, the substrate comprising: granular particles adhered together to form a body having a network of pores and passages, the interior surfaces of which are non-reactive and non-absorptive with respect to the volatile material to be dispensed; and a volatile material disposed in the pores; wherein the substrate is formed into a shape suitable for being inserted in the slot; wherein the volatile material comprises an insect control active ingredient selected from the group consisting of natural pyrethrins, pyrethrum extract, synthetic pyrethroids, and mixtures thereof; wherein activation of the volatile dispensing device releases the volatile material from the pores, which volatile material is then dispensed; and wherein the substrate is configured, and the volatile material is selected, so that the substrate can be heated so that no more than 10% residual volatile material remains in the pores when such heating has so depleted the volatile material from the substrate as to no longer be able to deliver the volatile material at an insect controlling rate.
