What the order directs

The order sets a federal policy of reducing tick and mosquito populations and the diseases they spread through land management, detection, prevention, treatment and technologies including sterile-insect techniques. It directs agencies to develop a campaign in Washington, D.C.; it does not establish that the campaign or any population reduction has already occurred.

The text sets goals for the D.C. campaign to reduce specified invasive mosquito populations by 90 percent and the tick population by 50 percent by 2028. These are future targets in the order, not measured results or guarantees.

Who must do what

Within 60 days, the Interior and Agriculture Secretaries and the heads of the Environmental Protection Agency (EPA) and General Services Administration, consulting Health and Human Services (HHS), are directed to develop and implement the D.C. campaign. It covers breeding grounds on federally controlled land, pest transport and host populations, potential commercial and cooperative approaches, and a plan involving the D.C. government where appropriate.

Within 60 days, EPA is directed to submit a regulatory framework for planned development and environmental release of advanced control technologies, and to prioritize methods or products it finds safe and effective. Agriculture and HHS are also directed to explore options for labeling products containing significant amounts of alpha-galactose.

Within 90 days, HHS is directed to announce prize competitions or direct research on diagnostics, prevention and treatments for tick- and mosquito-borne diseases, and to review candidate immunotherapies for alpha-gal syndrome. Agriculture, coordinating with other agencies, is directed to support research on non-chemical ways to reduce disease and pest populations.

Named implementation roles in Executive Order 14433
Agency / officialDirection in the signed textTiming and limits
Interior SecretaryJointly develop and implement the D.C. campaign; coordinate Agriculture’s non-chemical research; review available resources with other agency heads and OMB. Interior bears publication costs.Section 3(a): campaign within 60 days; population goals by 2028. Section 3(d): research work within 90 days. Resource review and publication costs have no separate numerical deadline.
Agriculture SecretaryJointly implement the campaign; consult on EPA’s framework; announce prizes or direct non-chemical research with Interior, HHS and EPA; explore alpha-galactose labeling with HHS; review resources.Section 3: campaign, EPA consultation and labeling exploration within 60 days; non-chemical prizes or research within 90 days. Exploration is not itself a final labeling requirement.
EPA AdministratorJointly implement the campaign; develop the technology-release framework with Agriculture and HHS; prioritize qualifying safe and effective products; coordinate on non-chemical research.Sections 3(a)–(b): within 60 days, including submission of the framework to the President through the Homeland Security Advisor. Section 3(d): research coordination within 90 days.
General Services AdministratorJointly develop and implement the D.C. campaign with Interior, Agriculture and EPA, consulting HHS.Section 3(a): within 60 days, with the campaign’s population-reduction objectives set for 2028.
HHS SecretaryConsult on the campaign and EPA framework; announce prizes or direct disease-related research; review alpha-gal immunotherapies and develop a research agenda; explore labeling with Agriculture; coordinate research and review resources.Section 3: campaign/framework consultation and labeling exploration within 60 days; diagnostics, prevention, treatment and immunotherapy work within 90 days. No separate numerical resource-review deadline.
Assistant to the President and Homeland Security AdvisorReceive and transmit EPA’s proposed regulatory framework to the President.Section 3(b)(i): part of EPA’s 60-day submission route; not a separate approval or product-registration deadline.
Government of the District of ColumbiaNamed consultation partner, as appropriate, for the campaign plan covering controls across D.C. communities.Section 3(a)(iv): consultation in developing the 60-day campaign; the order does not separately command a local appropriation or blanket local authorization.
Other relevant agency heads and OMB DirectorRelevant agency heads join Interior, Agriculture and HHS in reviewing available implementation resources, in coordination with OMB.Section 3(f): no separate numerical deadline and no new appropriation created by this review.

All 60- and 90-day clocks run from September 29, 2026, not publication on October 2. The campaign targets a 90 percent reduction in specified invasive mosquito populations and a 50 percent tick reduction by 2028; those are objectives, not reported results. The text allows prize announcements or directed research rather than requiring both, and preserves applicable law and available appropriations. Federal Register — full signed text and section references.

What the text does not establish

The order cites earlier orders concerning D.C. public spaces and biological research, but it does not itself demonstrate that a new product has been registered, a treatment approved, or a health outcome achieved. Agency action remains subject to applicable law and available appropriations. The 60- and 90-day periods are instructions to agencies measured from the signing date.

What happened next

The Federal Register published Executive Order 14433 on October 2, 2026. It sets deadlines for agencies to develop pest-control efforts in Washington, D.C., and calls for population-reduction targets by 2028; the order also assigns research, prize-competition, and product-review work.

The campaign combines land work, host control and biotechnology

The D.C. campaign is more specific than a general direction to spray for pests. Section 3(a) calls for landscaping and drainage changes on federally controlled land, with mowing and rain gardens as examples. It also covers pest transport and host populations, including rodents and deer, and prioritizes commercial capabilities or cooperative agreements. The community-land component involves consultation with the D.C. government where appropriate. The policy separately calls for protecting beneficial insects, native plants and animals while pursuing population reductions. Federal Register, sections 2(c) and 3(a).

EPA's proposed framework must consider sterilization, genetic modification and beneficial bacteria. Section 3(b) routes it to the President through the homeland security adviser and links it to the biological-research safeguards in EO 14292. The instruction to accelerate methods or register products applies to those EPA finds safe and effective. Section 3(f) also requires Interior, Agriculture, HHS and other relevant agencies to review available implementation resources with OMB. It gives that resource review no separate numerical deadline. Federal Register, section 3(b) and (f).

The regulatory and research work predates this order

The distinction between exploring biotechnology and authorizing its release is concrete. In a May 27, 2026, statement, EPA said an earlier experimental-use permit for genetically engineered mosquitoes had expired in 2024, that no U.S. releases were then authorized, and that unauthorized release would violate the Federal Insecticide, Fungicide, and Rodenticide Act. That statement describes the position before EO 14433; it does not determine whether a later permit was issued. The new order directs regulatory work rather than supplying a product-specific release authorization. EPA's May 27 statement; EO 14433, section 3(b).

HHS's Lyme Innovation record also shows an existing research base. Its timeline dates the initiative to November 20, 2018, the LymeX public-private accelerator to October 2020, and the first LymeX Diagnostics Prize phase to May 2022. That phase sought methods for detecting active Lyme infections and awarded $1 million across ten winners. Those are earlier diagnostic-development activities, not accomplishments caused by the September 2026 order. This record documents a diagnostic-development program already operating before EO 14433.
