Federal Order Sets New Mosquito and Tick Targets for Washington

Agencies have 60 days to develop a D.C. campaign, with population-reduction goals for 2028 and an emphasis on non-chemical methods.

A directive with a timetable

A September 29 executive order directs federal agencies to develop and implement a pest-control campaign in Washington within 60 days. It sets 2028 goals of reducing targeted invasive mosquito populations by 90 percent and ticks by 50 percent. These are policy targets, not measurements of reductions already achieved.

How the campaign would operate

The order identifies habitat improvements on land under federal jurisdiction, including landscaping and drainage. It also emphasizes targeted controls and technologies such as sterile insect methods. A community-wide plan is to be developed with consultation with the District government as appropriate.

A shared urban environment

Pest control connects the management of land with conditions people experience across a neighborhood. Federal property and District communities are therefore related parts of the planned campaign. Responsibility for a particular parcel still matters when deciding who can undertake a change and how that work is coordinated.

Targets require measurements

A reduction goal needs a credible starting point and a consistent way to count change. A lower count in one place or season may not establish the same result across the city. Assessing progress will require attention to where observations are made, when they are made and which populations are being measured.

Balancing outcomes

The order also seeks to avoid harmful effects on beneficial insects, native plants and animals. That introduces a second question alongside the headline targets: whether a method produces the intended control without unwanted effects. Claims of success should address both outcomes rather than relying on a single percentage.

Implementation is the next stage

The campaign will depend on agency decisions, resources and the available legal authority. The order explicitly makes implementation subject to applicable law and appropriations. Residents should expect further details about locations and methods; the directive itself does not establish that a particular neighborhood treatment has begun.
