The procurement solicits aerial applicators to provide comprehensive mosquito control services, including aerial larvicide and ultra-low volume (ULV) insecticide applications across 20,000 to 190,000 acres. Successful bidders must deploy multi-engine fixed-wing commercial agricultural aircraft equipped with GPS guidance, real-time meteorological monitoring systems, and night-vision capabilities. Pilot qualifications are stringent, requiring a minimum of 1,500 logged flight hours, with at least 500 hours specifically in aerial mosquito control applications. The contractor must guarantee aircraft and ground support team availability within 48 hours of county notification and provide post-application support and mission reporting. Evaluation criteria will likely include operational capabilities, aircraft specifications, pilot experience, and comprehensive insurance coverage.

No specific set-aside designations for disadvantaged enterprises were mentioned in the solicitation documents. The contract term extends through September 30, 2026, with an option for renewal for up to five additional one-year terms under the same conditions. Insurance requirements are extensive, including workers' compensation, commercial general liability (with $2,000,000 aggregate limits), aircraft liability ($1,000,000 minimum), and a $5,000,000 commercial umbrella liability policy. While specific budget ranges are not explicitly stated, pricing will be submitted on a per-acre basis covering services for 20,000 to 190,000 acres. The total contract value will depend on the actual acres treated and the bid price per acre. The contract will be awarded through a formal recommendation process, with the Board of Ada County Commissioners reviewing bids on January 26, 2026, and making a final recommendation on February 3, 2026, with potential final board approval on February 17, 2026.
