Basis of Presentation [Abstract]
Acquisition	*Acquisition* In December 2012, the Company acquired the remaining majority interest in FourStar Microbial Products, LLC (Four Star Microbial) for approximately $4.8 million in cash with possible contingent future performance-based payments. The Company has not yet finalized its allocation of the purchase price to the fair value of the net assets acquired. The operating results of FourStar Microbial had no impact on the consolidated financial statements and the purchase price paid is included in other assets on the condensed consolidated balance sheets. While the acquisition is not expected to have a material impact on the Company’s 2013 financial results, it will enhance its capability to service professional providers of mosquito abatement.
Noncontrolling Interest	*Noncontrolling Interest* Noncontrolling interest in the Company’s condensed consolidated financial statements represents the 20% interest not owned by Central in a consolidated subsidiary. Since the Company controls this subsidiary, its financial statements are fully consolidated with those of the Company, and the noncontrolling owner’s 20% share of the subsidiary’s net assets and results of operations is deducted and reported as noncontrolling interest on the consolidated balance sheets and as net income (loss) attributable to noncontrolling interest in the consolidated statements of operations. See Note 7, Supplemental Equity Information, for additional information.
Derivative Instruments	*Derivative Instruments* The Company principally uses a combination of purchase orders and various short and long-term supply arrangements in connection with the purchase of raw materials, including certain commodities. The Company also enters into commodity futures, options and swap contracts to reduce the volatility of price fluctuations of corn, which impacts the cost of raw materials. The Company’s primary objective when entering into these derivative contracts is to achieve greater certainty with regard to the future price of commodities purchased for use in its supply chain. These derivative contracts are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into derivative contracts for speculative purposes and does not use leveraged instruments. The Company does not perform the assessments required to achieve hedge accounting for commodity derivative positions. Accordingly, the changes in the values of these derivatives are recorded currently in other income (expense) in its condensed consolidated statements of operations. See Note 3, Derivative Instruments, for additional information.
Recent Accounting Pronouncements	*Recent Accounting Pronouncements* *Comprehensive Income* In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income.” ASU No. 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements, eliminating the option to present other comprehensive income in the statement of changes in equity. Under either choice, items that are reclassified from other comprehensive income to net income are required to be presented on the face of the financial statements where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued an update to ASU no. 2011-05, ASU No. 2011-12, which was issued to defer the effective date for amendments to the reclassifications of items out of accumulated other comprehensive income in ASU No. 2011-05. ASU 2011-05 and the amendments in ASU No. 2011-12 are effective for fiscal years and interim periods within those years, beginning after December 15, 2011 and became effective for the Company on September 30, 2012. The Company elected to report other comprehensive income and its components in a separate statement of comprehensive income. While the new guidance changed the presentation of comprehensive income, there were no changes to the components that are recognized in net income or other comprehensive income as determined under previous accounting guidance. The amended guidance did not have a material effect on the Company’s condensed consolidated financial statements. *Goodwill* In September 2011, the FASB issued ASU No. 2011-08, “Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment, which amended the guidance on the annual testing of goodwill for impairment. The amended guidance will allow companies to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment test required under current accounting standards. The guidance is effective for fiscal years beginning after December 15, 2011, and became effective for the Company on September 30, 2012. This new guidance did not have a material impact on the Company’s condensed consolidated financial statements. *Intangible Assets* In July 2012, the FASB issued an ASU No. 2012-02, “Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which simplifies the manner in which companies test indefinite-lived intangible assets for impairment. The ASU permits companies to first assess qualitative factors to determine whether events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform a quantitative impairment test. The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The guidance became effective for the Company on September 30, 2012. This new guidance did not have a material impact on the Company’s condensed consolidated financial statements.

Intangible Assets	*Intangible Assets* In July 2012, the FASB issued an ASU No. 2012-02, “Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which simplifies the manner in which companies test indefinite-lived intangible assets for impairment. The ASU permits companies to first assess qualitative factors to determine whether events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform a quantitative impairment test. The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The guidance became effective for the Company on September 30, 2012. This new guidance did not have a material impact on the Company’s condensed consolidated financial statements.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
