Fewer mosquitoes. Less pesticide. Across your whole district.
Nidus is built for mosquito control districts. It shows you where mosquitoes are being produced, sends your crews to the sources that matter, and keeps the record of what was found and what was done.
Fewer mosquitoes produced across your district
Every part of Nidus is aimed at one outcome: less standing water producing adults, and less pesticide spent to get there. Detection finds the water. The work eliminates it before it produces. The system remembers what worked, so effort lands on real production and gets more precise every season.
The water you never inspect is the water producing mosquitoes
- A pool turns green behind a fence and produces adults for weeks before anyone calls.
- Complaints arrive after the adults have already dispersed.
- Findings live in separate files, so nothing this season teaches the next one.
- Repeated chemical control is expensive and builds resistance.
Work the source, where the mosquitoes are made
Every mosquito comes from water. Nidus puts the district's effort there: find the water producing mosquitoes, get it eliminated, and keep the record that proves it.
The system that decides with you
Sites, visits, findings, notices, and communications live in one record, and what came of each decision shapes where the district looks next. FieldSeeker and MapVision intelligence comes in as it is, field capture runs offline, and the record carries forward season over season.
Weekly condition for every pool
Satellite coverage of the whole district each week, reporting which pools are holding untreated water so crews visit the ones that need attention.
Core and Reveal close the loop
Reveal finds the water. Core makes the finding part of the district's record and puts it to work. Either one runs on its own, and together a problem travels from detection to resolution inside one system.
Detection lands where the work happens
A weekly finding becomes a site in the district's record, with the visit, the notice, and the treatment attached to it.
Every resolved source is remembered
Work that closes a pool stays with that pool. Next season the district already knows which properties relapse and which stay clean.
Compliance answers itself
A flagged pool arrives with its history behind it, and an owner who says they drained it is confirmed by the next weekly capture, in the record that sent the notice.

A season running below the district's own five-year average
Several California districts run Nidus today. In one of them, trap counts this season are tracking below that district's own five-year average, and control effort came down with them.
Mosquitoes per trap, by week
The 2026 season against the same district's five-year average22% below the five-year average
Trap counts across the season to date, against that district's own five-year average for the same weeks.
Two-thirds lower by late season
Week 37 settled at 12.2 mosquitoes per trap, against a five-year week average of 37.0.
Less pesticide with it
Larvicide effort ran about 20% below the five-year average for the week, reported at 289.5 acres against 363.6.
