The method further includes the steps of aligning a nozzle of the dispensing device with the substrate and actuating the dispensing device to spray an amount of the air treatment material onto at least a portion of the substrate. ## Claims ### Claim 1 A method of operating an emanation system, comprising the steps of: attaching a substrate to a surface, the substrate including a first substrate and a secondary substrate attached to the first substrate; selecting an air treatment material including a fragrance having a first efficacy time period and an active ingredient having a second efficacy time period; aligning a nozzle of a dispensing device containing the air treatment material with the substrate; and actuating the dispensing device to spray an amount of the air treatment material onto at least a portion of the substrate, wherein the second efficacy time period is longer than the first efficacy time period, and wherein the secondary substrate is positioned to catch run-off from the amount of air treatment material sprayed onto the substrate. ### Claim 2 (depends on 1) The method of claim 1, wherein the air treatment material passively emanates from the first substrate at a first release rate, and passively emanates from the secondary substrate at a second release rate. ### Claim 3 (depends on 1) The method of claim 1 further including the step of filling the dispensing device. ### Claim 4 (depends on 1) The method of claim 1, wherein the nozzle is aligned with a visual guide on the substrate. ### Claim 5 (depends on 1) The method of claim 1, wherein the amount of air treatment material sprayed is about 3 grams. ### Claim 6 (depends on 1) The method of claim 1, wherein the amount of the air treatment material sprayed onto the substrate provides mosquito repellency and a pleasant fragrance to a room for a time period of about three days. ### Claim 7 (depends on 2) The method of claim 2, wherein the second release rate is slower than the first release rate. ### Claim 8 A method of operating an emanation system, comprising the steps of: attaching a substrate to a surface, the substrate including a first substrate having a front surface and a secondary substrate that is flush with the front surface; aligning a nozzle of a dispensing device containing an air treatment material with the substrate; and actuating the dispensing device to spray an amount of the air treatment material onto at least a portion of the substrate, wherein the secondary substrate is positioned to catch run-off from the amount of air treatment material sprayed onto the substrate, and wherein the air treatment material passively emanates from the first substrate at a first release rate, and passively emanates from the secondary substrate at a second release rate different from the first release rate. ### Claim 9 (depends on 8) The method of claim 8, wherein the second release rate is slower than the first release rate. ### Claim 10 (depends on 8) The method of claim 8, wherein a rear surface of the secondary substrate is flush with the front surface of the first substrate. ### Claim 11 (depends on 10) The method of claim 10, wherein a front surface of the secondary substrate is exposed. ### Claim 12 (depends on 8) The method of claim 8, wherein a lower edge of the secondary substrate is aligned with a lower edge of the first substrate. ### Claim 13 (depends on 8) The method of claim 8, wherein a front surface of the secondary substrate is flush with the front surface of the first substrate. ### Claim 14 (depends on 13) The method of claim 13, wherein the front surface of the secondary substrate is exposed. ### Claim 15 (depends on 14) The method of claim 14, wherein an upper edge of the secondary substrate is aligned with a lower edge of the first substrate. ### Claim 16 (depends on 8) The method of claim 8, wherein the second release rate is slower than the first release rate. ### Claim 17 (depends on 16) The method of claim 16, wherein the first release rate is 0.1 mg/hr to 1 mg/hr. ### Claim 18 (depends on 17) The method of claim 17, wherein the second release rate is 0.05 mg/hr to 0.1 mg/hr. ### Claim 19 (depends on 18) The method of claim 18, wherein the air treatment material includes a fragrance having a first efficacy time period and an active ingredient having a second efficacy time period. ### Claim 20 (depends on 19) The method of claim 19, wherein the second efficacy time period is longer than the first efficacy time period.
