Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
BASIS OF PRESENTATION | BASIS OF PRESENTATION Nature of Business SenesTech, Inc. (referred to in this report as “SenesTech,” the “Company,” “we” or “us”) was incorporated in the state of Nevada in July 2004. On November 12, 2015, the Company subsequently reincorporated in the state of Delaware. Our corporate headquarters and manufacturing site are in Phoenix, Arizona. We have developed and are commercializing a global, proprietary technology for managing animal pest populations, initially rat populations, through fertility control with our product known as ContraPest. ContraPest is a liquid bait containing the active ingredients 4-vinylcyclohexene diepoxide and triptolide. ContraPest limits reproduction of male and female rats beginning with the first breeding cycle following consumption. ContraPest is being marketed for use in controlling Norway and roof rat populations. In addition to the U.S. Environmental Protection Agency registration of ContraPest, we must obtain registration from the various state regulatory agencies prior to selling in each state. To date, we have received registration for ContraPest in all 50 states and the District of Columbia, 49 of which have approved the removal of the Restricted Use designation, as well as the District of Columbia and five major U.S. territories. Going Concern Our condensed financial statements as of March 31, 2023 were prepared under the assumption that we would continue as a going concern. The reports of our independent registered public accounting firm that accompanies our financial statements for each of the years ended December 31, 2022 and December 31, 2021 contain a going concern qualification in which such firm expressed substantial doubt about our ability to continue as a going concern, based on the financial statements at that time. Specifically, we have incurred operating losses since our inception, and we expect to continue to incur significant expenses and operating losses for the foreseeable future. These prior losses and expected future losses have had, and will continue to have, an adverse effect on our financial condition. If we encounter continued issues or delays in the commercialization of ContraPest, our expected future losses could have an adverse effect on our financial condition and negatively impact our ability to fund continued operations, obtain additional financing in the future and continue as a going concern. There are no assurances that such financing, if necessary, will be available to us at all or will be available in sufficient amounts or on reasonable terms. Our financial statements do not include any adjustments that may result from the outcome of this uncertainty. If we are unable to generate additional funds in the future through additional financings, sales of our products, licensing fees, royalty payments or from other sources or transactions, we will exhaust our resources and will be unable to continue operations. Liquidity and Capital Resources Since our inception, we have sustained significant operating losses in the course of our research and development and commercialization activities and expect such losses to continue for the near future. We have generated limited revenue to date from product sales, research grants and licensing fees received under a former license agreement. We have primarily funded our operations to date through the sale of equity securities, including convertible preferred stock, common stock and warrants to purchase common stock. We have also raised capital through debt financing, consisting primarily of convertible notes and government loan programs, and, to a lesser extent, payments received in connection with product sales, research grants and licensing fees. As of March 31, 2023, we had an accumulated deficit of $124.2 million and cash and cash equivalents of $2.7 million. Our ultimate success depends upon the outcome of a combination of factors, including the following: (i) successful commercialization of ContraPest and maintaining and obtaining regulatory approval of our products and product candidates; (ii) market acceptance, commercial viability and profitability of ContraPest and other products; (iii) the ability to market our products and establish an effective sales force and marketing infrastructure to generate significant revenue; (iv) the success of our research and development; (v) the ability to retain and attract key personnel to develop, operate and grow our business; and (vi) our ability to meet our working capital needs. Based upon our current operating plan, we expect that cash and cash equivalents at March 31, 2023, in combination with anticipated revenue and any additional sales of our equity securities (see Note 10), will be sufficient to fund our current operations for at least the next six months. While we have evaluated and continue to evaluate our operating expenses and concentrate our resources toward the successful commercialization of ContraPest in the United States, additional financing will be needed before achieving anticipated revenue targets and margin targets If we are unable to raise necessary capital through the sale of our securities, we may be required to take other measures that could impair our ability to be successful and operate as a going concern. In any event, additional capital is needed in order to fund our operating losses and research and development activities before we become profitable. We may never achieve profitability or generate positive cash flows, and unless and until we do, we will continue to need to raise capital through equity or debt financing. If such equity or debt financing is not available at adequate levels or on acceptable terms, we may need to delay, limit or terminate commercialization and development efforts or discontinue operations. Condensed Financial Statements Our accompanying unaudited condensed financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with the U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited condensed financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of March 31, 2023, and our operating results and cash flows for the three-month periods ended March 31, 2023 and 2022. The accompanying financial information as of December 31, 2022 is derived from audited financial statements. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 17, 2023. Recent Accounting Pronouncements There have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our condensed financial statements. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and classification of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The significant estimates in our financial statements include the valuation of inventory, common stock warrants, and stock-based awards, such as stock options and restricted stock units. Actual results could differ from such estimates. Comprehensive Loss We have no other comprehensive income items for the periods presented. As a result, our net loss and comprehensive loss were the same for the periods presented and a separate statement of comprehensive loss is not included in the accompanying condensed financial statements. |

Share-Based Payment Arrangement [Abstract] | |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION In 2018, our stockholders approved the adoption of the SenesTech, Inc. 2018 Equity Incentive Plan (the “2018 Plan”). The 2018 Plan has since been amended and restated on certain occasions, most recently on October 12, 2022, when our stockholders approved an increase to the total number of authorized shares to 348,614 shares. Stock options are generally issued with a per share exercise price equal to the fair market value of our common stock at the date of grant. Options granted generally vest immediately, or ratably over a 12- to 36-month period coinciding with their respective service periods, with terms of generally five years. Certain stock option awards provide for accelerated vesting upon a change in control. As of March 31, 2023, we had 164,522 shares of common stock available for issuance under the 2018 Plan.

Earnings Per Share [Abstract] | |
LOSS PER SHARE | LOSS PER SHARE Basic loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted loss per share attributable to common stockholders is computed by dividing the loss attributable to common stockholders by the weighted average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury stock and if-converted methods. For purposes of the computation of diluted loss per share attributable to common stockholders, common stock purchase warrants, and common stock options are considered to be potentially dilutive securities but have been excluded from the calculation of diluted loss per share attributable to common stockholders because their effect would be anti-dilutive given the net loss reported for the three months ended March 31, 2023 and 2022. Therefore, basic and diluted loss per share attributable to common stockholders are the same for each period presented. The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted loss per share attributable to common stockholders (in common stock equivalent shares): Three Months Ended 2023 2022 Common stock warrants $ 3,184,810 $ 226,572 Restricted stock units — 33 Common stock options 280,448 72,366 $ 3,465,258 $ 298,971 |

CONTINGENCIES | CONTINGENCIES Legal Proceedings In July 2020, Kennan E. Kaeder, our former corporate general counsel (the “Plaintiff”), commenced an action against us in the Superior Court of the State of California, for the County of San Diego. The complaint alleges, among other things, that we breached the Plaintiff’s employment contract with us, as well as the implied covenant of good faith and fair dealing, by refusing to issue him the balance of stock options he claims we owe him. In September 2021, the Plaintiff served us and also named the following individuals as defendants: Loretta Mayer, Cheryl Dyer, Thomas C. Chesterman, Kim Wolin, Grover Wickersham, Marc Dumont, Bob Ramsey, Matthew Szot, Julia Williams, and Bill Baker. We do not believe that all of the defendants have yet been served.

Subsequent Events [Abstract] | |
SUBSEQUENT EVENTS | SUBSEQUENT EVENTS On April 12, 2023, we consummated a registered direct offering with certain institutional investors and issued an aggregate of 857,146 shares of our common stock for $1.75 per share for gross proceeds of $1.5 million, before deducting fees payable to the placement agent and other estimated offering expenses payable by us. The shares were offered and sold pursuant to a prospectus, dated May 6, 2022, and a prospectus supplement, dated April 10, 2023, in connection with a takedown from our shelf registration statement on Form S-3 (File No. 333-261227). In connection with the registered direct offering, the following warrants were issued: • Series C warrants to the investors in the offering to purchase up to 857,146 shares of our common stock. The Series C warrants are exercisable immediately with an exercise price of $1.62 per share, and expire five and one-half years from the date of issuance, or October 12, 2028. • Placement agent warrants to purchase up to 64,286 shares of our common stock. The placement agent warrants will be exercisable immediately upon issuance, with an exercise price per share of $2.1875 per share, and expire five years following the date of issuance, or April 10, 2028. We have evaluated subsequent events from the balance sheet date through May 11, 2023, the date at which the condensed financial statements were issued, and determined that there were no additional items that require adjustment to or disclosure in the condensed financial statements. |

Condensed Financial Statements | Condensed Financial StatementsOur accompanying unaudited condensed financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with the U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited condensed financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of March 31, 2023, and our operating results and cash flows for the three-month periods ended March 31, 2023 and 2022. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements There have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our condensed financial statements. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and classification of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The significant estimates in our financial statements include the valuation of inventory, common stock warrants, and stock-based awards, such as stock options and restricted stock units. Actual results could differ from such estimates. |
Comprehensive Loss | Comprehensive Loss We have no other comprehensive income items for the periods presented. As a result, our net loss and comprehensive loss were the same for the periods presented and a separate statement of comprehensive loss is not included in the accompanying condensed financial statements. |
Cash and Cash Equivalents | Cash and Cash Equivalents Highly liquid investments with maturities of three months or less as of the date of acquisition are classified as cash equivalents, of which we had $2.7 million and $4.8 million as of March 31, 2023 and December 31, 2022, respectively, included within cash and cash equivalents in the condensed balance sheets. |
