         1 . A pre-melt composition for a scented cellulosic insect repellent comprising; a pre-melt cellulosic; a plasticizer; a fragrance component; and a solvent system that comprises a component that has both a non-polar and polar character, wherein the fragrance component repels wildlife or insects.  
     
     
         2 . The pre-melt composition for a scented cellulosic insect repellent of  claim 1 , wherein the solvent system comprises a component that is soluble in both an alcohol and benzene.  
     
     
         3 . An insect repellent composition comprising; a cellulosic; a plasticizer; a fragrance component; and a glycol or glycol ether, wherein the fragrance component repels wildlife or insects.  
     
     
         4 . (canceled)  
     
     
         5 . The insect repellent composition of  claim 3 , wherein the glycol is a C 5 -C 10  substituted or unsubstituted alkylene glycol or a poly(C 5 -C 10  substituted or unsubstituted alkylene glycol).  
     
     
         6 . The insect repellent composition of  claim 3 , wherein the glycol is a C 5 -C 7  substituted or unsubstituted alkylene glycol or a poly(C 5 -C 7  substituted or unsubstituted alkylene glycol).  
     
     
         7 . The insect repellent composition of  claim 3 , wherein the glycol is hexylene glycol.  
     
     
         8 . The insect repellent composition of  claim 3 , wherein the plasticizer is selected from dibutyl phalate, diethyl phthalate, dimethyl phthalate, triacetin, diethylhexyl-phthalate, and dioctyl phthalate.  
     
     
         9 . The insect repellent composition of  claim 3 , wherein the glycol ether is an alkyl ether of alkylene glycol or poly(alkylene glycol).  
     
     
         10 . The insect repellent composition of  claim 3 , wherein the glycol ether is a C 4 -C 7  mono or poly alkyl ether of an alkylene glycol or polyalkylene glycol  
     
     
         11 . (canceled)  
     
     
         12 . The insect repellent composition of  claim 10 , wherein the alkylene glycol is diethylene glycol.  
     
     
         13 . The insect repellent composition of  claim 3 , wherein the glycol ether is butyl carbitol.  
     
     
         14 . The insect repellent composition of  claim 3 , wherein the glycol ether is selected from propylene glycol monoethyl ether, dipropylene glycol monoethyl ether, and tripropylene glycol monoethyl ether.  
     
     
         15 . (canceled)  
     
     
         16 . A process for preparing a scented cellulosic insect repellent with optimal fragrance intensity, comprising the steps of: (a) determining an amount of net plasticizer to be added to a pre-melt cellulosic composition; (b) selecting a high preliminary fragrance:plasticizer weight ratio of the net plasticizer; (c) adding the net plasticizer with the high preliminary fragrance:plasticizer ratio; (d) determining the fragrance:plasticizer weight ratio of net plasticizer that achieves maximum fragrance intensity in the processed scented cellulosic by decreasing the fragrance:plasticizer ratio of the net plasticizer in iterative trials; (e) selecting a final fragrance:plasticizer ratio based on the desired fragrance intensity of the scented cellulosic, wherein the final fragrance:plasticizer ratio is less than or equal to the fragrance:plasticizer ratio in step (d) that achieves the maximum fragrance intensity, and wherein the fragrance repels wildlife or insects.  
     
     
         17 . The process for preparing a scented cellulosic insect repellent of  claim 16 , wherein the high preliminary fragrance:plasticizer weight ratio is 2 or higher.  
     
     
         18 . The process for preparing a scented cellulosic insect repellent of  claim 17 , wherein the high preliminary fragrance:plasticizer weight ratio is 4 or higher.  
     
     
         19 . (canceled)  
     
     
         20 . (canceled)  
     
     
         21 . The insect repellent composition of  claim 3  wherein the fragrance component repels wildlife.  
     
     
         22 . The insect repellent composition of  claim 3  wherein the fragrance component repels insects.  
     
     
         23 . The insect repellent composition of  claim 22  wherein the composition is in the form of lawn furniture.  
     
     
         24 . The process for preparing a scented cellulosic insect repellent of  claim 16  wherein the fragrance repels wildlife.  
     
     
         25 . The process for preparing a scented cellulosic insect repellent of  claim 16  wherein the fragrance repels insects.
