Senecio, the EIC Accelerator and Israel's Sterile Mosquito Factory

Since the summer of 2023, the parks of Kfar Saba in central Israel have been stocked with mosquitoes that do not bite. They are sterile males, reared, sorted by robots and irradiated by Senecio, a local start-up, and released weekly to mate with wild females whose eggs then never hatch, according to Ynet and Kfar Saba News. In 2020 the European Innovation Council selected the company in the Green Deal round of its EIC Accelerator pilot and gave it blended finance, a grant plus equity, for RoboSIT, a project to industrialise this sterile insect technique (SIT) with artificial intelligence.

The European Commission's list of winners of the 19 May 2020 cut-off names Senecio of Kfar Saba as the only company on RoboSIT, with "blended finance". CORDIS records an EU grant of €1,401,487 towards a total cost of €2,002,125, from 1 December 2020 to 31 May 2023. The proposal promised a launch "in the EU and US in 2023", revenues "toward €49m 2 years later" and more than 100 staff within five years. Three years after the project closed, the sterile males are on sale in Israel, by subscription and courier. The European and American launch has not been announced.

What Senecio Does Today

Senecio is operating. Its Hebrew website sells a 2026 season subscription: from March to October, a courier brings a box of sterile males to a customer's garden every two weeks, and the customer opens it outdoors. The service targets the Asian tiger mosquito in a list of towns in central and northern Israel, from Tel Aviv and Petah Tikva to Zichron Yaakov. A private garden of up to 300 square metres costs 249 shekels a month. The company states it has worked in Israel for about three years and reports reductions of up to about 90%; it publishes no measured data for that figure.

Municipal work runs through Rentokil Israel, the local arm of the global pest control group Rentokil. Senecio's blog says the two signed a commercial agreement for 2024 after a 2023 pilot, and served seven municipalities and communities that season: Modi'in, Zichron Yaakov, Sde Warburg, Kibbutz Eyal, Nir Eliyahu, Atlit and Be'er Yaakov. In April 2025 Maariv reported that Petah Tikva had started releasing Senecio's sterile males with Rentokil Israel. In September 2025 Kfar Saba, the first city to use the method in summer 2023, said it was expanding the programme, and that a paper by the two companies had been accepted at an international urban pest conference in Sweden in July 2025, according to Kfar Saba News. Neither the municipalities nor the company have published mosquito counts or a contract value.

The latest step abroad is a plan, not a deployment. On 29 December 2025 Senecio announced a memorandum of understanding with BVG India, a professional services company with more than 100,000 employees, to localise production of sterile males in India, according to a company release and The CSR Universe. Neither names a site, a date or a budget. "This MoU represents a practical step toward making SIT operational at scale," Lepek said.

The Technology: Robots That Sort Mosquitoes by Sex

Only female mosquitoes bite. The sterile insect technique releases large numbers of sterile males; a female mates once, and if her partner is sterile her eggs do not hatch, so repeated releases shrink the population without insecticides. The method's bottleneck is separating males from females. In a Spanish pilot against the tiger mosquito, which released more than 15 million sterile males over 80 hectares from 2018 to 2020, pupae were separated by size on a plate separator and technicians removed remaining females by hand; the researchers wrote that "the labor invested in sex sorting is considerably high", in the journal Insects. Senecio's RoboSIT objective said the same of manual sorting: "the global impact of manual SIT is negligible".

Senecio's answer is image recognition. Its machines photograph adult mosquitoes, a neural network classifies each one's sex, females are removed and males are loaded into release cartridges, according to the CORDIS Results in Brief, which gives a capacity of up to about 20 million mosquitoes a week. Its SIT HUB page describes a modular plant that breeds, sorts, sterilises with controlled radiation and packs males, and claims it sorts "hundreds" of mosquitoes per second. No independent measurement of that throughput has been published.

The approach differs from its best-known rivals. Verily, Alphabet's life sciences unit, also built a robot to rear and sex-sort mosquitoes, but its males carry the Wolbachia bacterium rather than being irradiated, according to MIT Technology Review. Senecio says on its SIT HUB page that its mosquitoes are not genetically modified, which it argues keeps regulation light.

The business has also changed shape. In 2018 Senecio told The Times of Israel that it did not produce or sterilise mosquitoes itself and would sell sorting and release equipment, including a pod tested under an aircraft in the US, to local producers. Today it rears the mosquitoes in its own factory, which Ynet places near Kfar Saba, and sells the service to towns and households.

What RoboSIT Promised, and What CORDIS Shows

RoboSIT ran for 30 months under the Green Deal topic of the EIC Accelerator pilot, with Senecio as the only participant. The objective set out three linked products: an AI robot to identify and pool mosquitoes caught in surveillance traps for pathogen testing, mass-rearing factories with robotic sex sorting, and a system in which "pathogen detection will trigger the release of millions of sterile males". The final periodic report, for December 2021 to May 2023, lists automated monitoring, a second-generation sorting and packaging unit, a prototype drone release system, a cloud platform for trap results and "a complete demo site". It says that by the end of the project Senecio had signed with "the largest pest control company in the world" and was releasing sterile mosquitoes in "some 5 different cities". The Results in Brief, updated in October 2023, says "nearly 10 cities in Israel"; the two CORDIS texts do not explain the difference.

The engineering core of RoboSIT was delivered: the robots sort, the factory runs and sterile males are on the market. The commercial promises that justified the award, the transatlantic launch, the revenue and the jobs, have no public evidence behind them. The pathogen-triggered release, the most distinctive idea in the proposal, has not been shown outside the report's description of the separate surveillance robot.

The Money and the Register

Senecio has not disclosed the size of the EIC award. A December 2020 release was headlined "US$12 Million from the European Commission", while its text says only that the blended investment includes "both equity and grant components". The EIC Fund lists Senecio among the companies it has invested in, so the equity part was paid, but neither the Fund nor the company gives the amount or the date. Calcalist's 2022 profile names Pareto VC, Pamoja Capital, Ocean Azul Partners and two Israeli agricultural investors; the 2020 release names Pamoja and Ocean Azul. No funding round after 2020 has been announced.

The company register shows a gap. In the Israeli Corporations Authority's open company data, updated on 15 October 2026, Senecio Ltd is active but flagged as a "violating company" (מפרה), with 2017 as the last year for which it filed an annual report, and its address is still a Haifa incubator rather than Kfar Saba. OpenCorporates shows the same status and address. The Registrar applies the label to companies that miss annual reports or annual fees after a warning, and it can block registration of new charges and name changes, according to law firms Barnea Jaffa Lande and IsraelLaw.info. Israeli private companies do not publish their accounts, so Senecio's revenue, losses and headcount cannot be checked.

Why Europe Should Care

The mosquito Senecio fights in Israeli gardens is spreading through Europe. The Asian tiger mosquito is established in 369 regions of 16 European countries, up from 114 regions a decade earlier, and Europe recorded 27 chikungunya outbreaks by August 2025, a record, according to the European Centre for Disease Prevention and Control (ECDC), which called for "environmentally friendly mosquito control interventions". The Commission has set non-binding targets to cut the use and risk of chemical pesticides by 50% and the use of the most hazardous pesticides by 50%, against a 2015 to 2017 baseline, according to its food safety directorate. A non-chemical, non-GM method that scales is exactly what both agendas ask for. So far, the EU-funded version of it serves Israel.
