Guide for mosquito control companies · checked 15 November 2026
Mosquito control software that runs 21-day rounds inside the label
A mosquito company sells a season, not a visit: say a 21-day barrier program from mid-April to mid-October, about eight or nine rounds, each one a pyrethroid spray on the shrubs, fence line and shade where adults rest, plus a walk for standing water. The label decides how often you may come back at a given rate, the wind decides whether you spray today, and in Illinois or New York the state decides who must be told and what sign goes in the lawn. This guide covers those rules, what to record on every application, and how to set the business up.

A 30-minute call. We show you mosquito control companies workflows running in Fieldproxy, built around how you work.
Short answer
Mosquito control companies mostly run on pest control software: GorillaDesk sells a mosquito page with 14, 21 and 30-day cycles, chemical logs with EPA registration numbers and seasonal renewal texts; FieldRoutes and PestPac are used by larger pest companies that add mosquito as a service line; public mosquito abatement districts use GIS tools such as FieldSeeker for trap counts and larviciding. Whatever you pick, check that it can stop a visit being booked sooner than the label allows for the rate you spray, hold a route when the wind forecast passes 10 mph, and produce state notices and markers. Fieldproxy is one option. Best for processes that don't fit a template, set up for you: each yard holds its spray zones and no-spray zones, each program holds its product, rate and minimum interval, and the field app writes the full application record.

How a job runs
One mosquito control job, from first call to paid
The order the work really happens in, and what has to be written down at each step so nothing is argued about later.
- 1
Quote the yard from a map
Measure the treatable area in square feet, not the lot size: the shrub beds, tree line, fence line, under the deck and around the pool, where adults rest in shade. Mark what will not be sprayed (vegetable garden, flowering beds, pond or creek edge, beehives, a neighbor's line) on the same map, because it changes the gallons and the time on site.
- 2
Sell the season and pick the product
Offer the program the customer wants: a 21-day synthetic barrier, a 30-day high-rate round, a minimum-risk (25(b)) botanical program, an In2Care station add-on, or a one-off event spray. The product and rate decide the shortest legal gap between visits, so pick them before you set the round length.
- 3
Check the state rules for this address
Illinois: the applicator needs the state barrier mosquitocide certification, no spraying from 16 October to 14 April, and abutting neighbors who ask must be told the day before. New York: in counties that adopted the Neighbor Notification Law, certain commercial lawn applications need 48 hours' written notice to neighbors. Connecticut and Illinois ban residential automatic misting systems, so do not sell or service one there.
- 4
Hold or release the day's route on the forecast
Before the trucks leave, check wind and rain for each slot. The Talstar TC label says do not apply when wind exceeds 10 mph and do not make applications during rain. Text affected customers a new date instead of sending a tech who will sit in the driveway.
- 5
Text the customer and the neighbors who asked
Send the day-before text: arrival window, keep pets and kids inside until the spray dries, leave the gate unlocked. Send the neighbor notices your state requires, in the form it requires: written in New York, written or electronic in Illinois, with a note left at the door if the neighbor cannot be reached.
- 6
Inspect and dump standing water
Walk the yard before spraying. Asian tiger mosquitoes breed in containers that hold water for seven days or more: saucers, buckets, tarps, tires, corrugated downspout pipe. Tip what can be tipped, and treat what cannot with a larvicide such as Bti dunks or methoprene briquets, logging each one.
- 7
Spray the resting sites
Mist blower or backpack sprayer onto the underside of leaves on shrubs and ground cover, the fence line, under decks and in shaded, humid spots such as ivy and azaleas where adults rest. Keep off blooming plants where bees are foraging and away from drains, gutters and water. Record the mix, gallons applied and area treated.
- 8
Post the marker and finish the record
In Illinois, place the 4 by 5 inch white marker reading 'STAY OFF TREATED SURFACE UNTIL DRY' at the usual entry points, bottom at least 12 inches above the turf. Photograph it, log start and stop time, wind reading and temperature, and close the visit.
- 9
Handle rain and callbacks
If heavy rain hits before the spray dries (Mosquito Squad's page says about 30 minutes in typical conditions), book a free retreat inside your policy. If the customer reports bites mid-cycle, log a callback against the round, so you can see which yards and techs generate them.
- 10
Bill the round and renew the season
Charge each round on completion or draw down the prepaid season. In late winter, send renewals with last season's rounds, callbacks and products, and roll the program forward with the state's season window applied.
What to record
The fields every mosquito control job should capture
Property and program
- Treatable area in sq ft by zone (front beds, back tree line, fence line, under deck, pool surround) and total gallons of finished mix it takes
- No-spray zones on the map: vegetable garden, flowering beds, pond, creek or drainage edge, beehives, play set, neighbor's line, with a reason for each
- Program: product, EPA Reg. No., rate per gallon, round length in days, season start and end, prepay or per round
- Neighbors who asked to be notified (name, address, phone or email) and the state rule that applies (Illinois day-before, New York 48-hour written)
- Gate code, dogs, irrigation schedule (sprinklers wash residue from treated surfaces), best and blocked days
Each application
- Applicator name and license number; Illinois barrier mosquitocide certification and its 3-year expiry
- Start and stop time, wind speed and direction, temperature, rain in the forecast
- Product, EPA Reg. No., rate (fl oz per gallon), gallons of finished mix applied, area treated in sq ft
- Zones treated and zones skipped with the reason (blooming and bees present, wind gusts, locked gate, kids in the yard)
- Containers tipped, larvicide placed (product, count, location: e.g. 2 Altosid briquets in the side-yard catch basin), In2Care stations refilled
- Photos: marker posted, standing water found, any drift-sensitive area next to the spray
Paperwork and proof
- Day-before customer text and the neighbor notices sent, with time and method (New York: English and Spanish)
- Marker photo per entry point where the state requires it
- Label and safety data sheet for each product, ready to send on request (Illinois requires it on request)
- Rain retreat and callback log per round
- Records of any application that reached water of the US and the quantity, if the yard or contract borders water (EPA Pesticide General Permit)
Rules and standards
The rules that shape the work, with their sources
| Rule | What it means on the job |
|---|---|
| Label rate and how it is applied | Talstar TC for adult mosquitoes outdoors: 0.33 to 1.0 fl oz per gallon of water, applied at one gallon of dilution per 1,000 sq ft (0.07 to 0.22 lb bifenthrin per acre). Never more than 1.0 fl oz per 1,000 sq ft per application. Use the high rate for residual control. source: EPA-stamped label, Talstar TC Flowable Termiticide/Insecticide (EPA Reg. 279-3206), mosquito control directions, 20 Apr 2016 |
| Retreatment interval depends on the rate | At the lower use rates, repeat applications are limited to once per seven days. At the high rate of 1.0 fl oz per gallon, do not apply more than once per four weeks. A 21-day program cannot run at that label's high rate. source: EPA-stamped label, Talstar TC Flowable Termiticide/Insecticide (EPA Reg. 279-3206), mosquito control directions, 20 Apr 2016 |
| Equipment, timing and wind | Apply with hand-held or backpack sprayers, mist blowers, ground, power or truck-mounted hydraulic sprayers. Not by air, and not with cold aerosol ULV or thermal foggers. Best applied when mosquitoes are most active, in the cooler hours of night or early morning. Do not apply when wind speed exceeds 10 mph. source: EPA-stamped label, Talstar TC Flowable Termiticide/Insecticide (EPA Reg. 279-3206), mosquito control directions, 20 Apr 2016 |
| Rain, drains and bees | Do not make applications during rain, and never directly into sewers, drains or gutters. The label advises calm weather with no rain predicted for 24 hours. It is highly toxic to bees: do not apply or allow drift to blooming crops or weeds while bees are foraging. source: EPA-stamped label, Talstar TC Flowable Termiticide/Insecticide (EPA Reg. 279-3206), mosquito control directions, 20 Apr 2016 |
| Illinois: season, wind, certification | No commercial barrier mosquitocide applications between 16 October and 14 April, and none when wind is 10 mph or more. Applicators must complete a Department of Agriculture approved barrier mosquitocide training (at least one hour) before treating a residence; the certification lasts three years. source: Illinois Department of Agriculture, Residential barrier mosquitocide applications |
| Illinois: marker, neighbors, misters | Immediately after the spray, a white 4 x 5 inch marker on a dowel at the usual entry points, bottom at least 12 inches above the turf, reading 'STAY OFF TREATED SURFACE UNTIL DRY'; the resident removes it the next day. Abutting neighbors who give their name, address and phone get notice at least the day before. No person may install or use a residential automatic misting system. Public health programs, 25(b) products and homeowners are exempt. source: Illinois Department of Agriculture, Residential barrier mosquitocide applications |

| New York Neighbor Notification Law | In Albany, Erie, Monroe, Nassau, Rockland, Suffolk, Tompkins, Ulster and Westchester counties and New York City, certain commercial lawn applications need at least 48 hours' written notice to neighbors, plus visual markers on residential lawns. Since 2020 the notice and markers must be in English and Spanish. Spot applications, granular products and soaps and oils are among the exemptions. source: New York State DEC, Neighbor Notification Law (ECL 33-1004 and 33-1005, 6 NYCRR 325.41) |
| Connecticut bans residential misting systems | The legislature voted in May 2018 to ban residential pesticide misting systems, the timer-driven units that spray adulticide around a yard every few minutes. Illinois has the same ban. source: Beyond Pesticides, Connecticut legislature bans residential mosquito misters (23 May 2018) |
| Clean Water Act permit when spray reaches water | Any mosquito application that discharges to waters of the US needs NPDES coverage, larviciding included. Under EPA's PGP, for-hire applicators are covered automatically without a Notice of Intent; mosquito districts and entities treating more than 6,400 acres a year with adulticides file NOIs. Every permittee keeps records of the pesticides discharged to water, with quantities and locations. source: US EPA, 2016 Pesticide General Permit: mosquito control activities fact sheet |
| Minimum-risk 'natural' programs | FIFRA 25(b) products may only contain listed ingredients (cedar oil and citronella among them), must list every ingredient, and cannot claim to control pests that affect anyone's health. A botanical program can be sold as nuisance relief, not as disease protection. Most states still register these products. source: National Pesticide Information Center, Minimum risk pesticides (FIFRA 25(b)) |
| Beekeeper notice for wide-area work | North Carolina requires 48 hours' notice to registered apiaries within one mile before an aerial application of a product toxic to bees. BeeCheck (FieldWatch) is a voluntary map where beekeepers register hives so applicators can check before spraying. source: NC Department of Agriculture, How to protect honeybees during wide-area mosquito applications (02 NCAC 09L .1009) |
| Larvicide briquets in catch basins | Altosid Briquets give up to 30 days of methoprene control. One briquet per catch basin up to 1,500 gallons (0 to 2 ft of water); four briquets for 4,500 to 6,000 gallons. Water flow shortens briquet life, so inspect and retreat. source: Altosid Briquets specimen label (EPA Reg. 2724-375), Cache Mosquito Abatement District |
| Container breeders decide where you look | Asian tiger mosquitoes breed in artificial containers that hold water for seven days or more, bite in the day as well as at dusk and dawn, rest in cool shaded bushes such as ivy and azaleas, and do not travel far from where they breed. Truck spraying in the evening is less effective against them. source: Fairfax County Health Department, Asian tiger mosquito container breeding fact sheet |

Where it breaks
Where spreadsheets and generic software fall over
The office sets every program to 21 days and the techs mix at the label's high rate for 'longer residual'. On that label, the high rate allows one spray per four weeks, so every round is off label.
Each program carries its product, rate and minimum retreatment interval from the label, and the schedule refuses a round sooner than that interval. Changing the rate changes the allowed round length.
Trucks go out on a gusty day, techs spray anyway or drive home, and the customer gets neither a treatment nor a text.
The day's route is checked against the forecast wind and rain per slot before dispatch; held stops get a new date and a text, and every application records the wind reading on site.
The pond, the vegetable garden and the neighbor's beehive live in one tech's head. A new hire sprays them in week one and the company eats the complaint.
No-spray zones sit on the property map with a reason, show on the field app before the tech starts, and each one is ticked as avoided on the record.
An Illinois neighbor asked to be told before each spray. The note was in an email the office never linked to the account, the neighbor saw the truck, and called the Department of Agriculture.
Neighbors who ask become records on the property, with the state rule attached. The day-before notice goes out with the customer text and the visit cannot close without it.
It poured 15 minutes after the tech left, the customer wants a free respray, and nobody knows when the spray ended or what the policy says.
The record holds the stop time; a rain event inside the policy window flags the round for a free retreat automatically, and the callback log shows the real retreat rate per tech.
Renewals go out as one generic email in March. Yards that had three callbacks last year get the same price and message as yards that never called.
Renewal drafts pull last season's rounds, skips, callbacks and products per yard, so the offer and the tone match what happened there.

Questions to ask any vendor
- Can a program carry the product, rate and minimum retreatment interval from the label, and will the schedule block a round sooner than that?
- Can you hold a day's route on forecast wind above 10 mph or rain, and text the customers a new date?
- Can each property hold no-spray zones on a map that the tech sees before spraying, and tick off on the record?
- Can you send Illinois day-before and New York 48-hour neighbor notices from the property record, in English and Spanish?
- Does the application record capture wind, temperature, gallons of finished mix, area treated and zones skipped, offline?
- Can a rain event after the stop time flag a free retreat, and can renewals use last season's rounds and callbacks per yard?

Mosquito control on Fieldproxy: built around how you already work
A Fieldproxy setup for a mosquito company is built around the yard and the season: each property holds its spray zones, no-spray zones and the neighbors who asked to be told, and each program holds the product, rate and the label's shortest gap between rounds. Routes are checked against the wind before trucks leave, techs work from an offline app that walks the standing-water check, the spray and the marker, and every round ends with a complete application record and a renewal that knows what happened in that yard.
Module 1
Property map and zones
Gallons, minutes on site and every complaint come back to what was sprayed and what was not.
- Record: Property, linked to Customer and (for HOAs and commercial) Contract; fields: treatable area sq ft, lot type, irrigation days, gate code, dogs, best and blocked days
- Child record: Zone (front beds, back tree line, fence line, under deck, pool surround) with sq ft and gallons of finished mix it takes
- Child record: No-spray zone (vegetable garden, flowering bed, pond or creek edge, beehive, play set, neighbor line) with a reason and a photo
- Map sketch on the quote, carried to every visit so the tech sees the same zones the salesperson drew
- Rule: a property can't be scheduled until every zone has an area and every no-spray zone has a reason
Module 2
Programs, products and label limits
The label decides how often you may come back at a given rate; the program has to know that before it books 10 rounds.
- Product library: name, EPA Reg. No., active ingredient and %, label rate range per gallon, max per 1,000 sq ft, minimum retreatment interval per rate, wind limit, bee warning, 25(b) yes/no
- Program record: type (21-day barrier, 30-day high rate, botanical 25(b), In2Care add-on, tick add-on, event), product, rate, round length, season start and end
- Rule: round length can't be shorter than the label interval for the product and rate (e.g. Talstar TC at 1.0 fl oz/gal: 28 days minimum)
- Rule: a 25(b) program's quote and texts can't use disease-protection wording
- State window per address (Illinois: rounds only 15 April to 15 October), applied when the season is generated
Module 3
Season quotes, prepay and renewals
Most revenue is sold in a few spring weeks as a whole season, and renewed the next year.
- Quote built from treatable sq ft, program and round count, with prepay, per-round and monthly options
- Status: Draft, Sent, Accepted, Scheduled, Active, Paused, Cancelled, Season complete
- Accepting the quote generates every round for the season with the state window and label interval applied
- Renewal record each winter with last season's rounds done, skipped, rain retreats and callbacks
Module 4
Weather holds and route release
A route sent into 15 mph gusts or a storm is a day of wages and an angry customer list.
- Each morning, every slot checked against forecast wind and rain (e.g. hold when wind is forecast above 10 mph or rain within 2 hours)
- Held visits move to the next open day inside the round's window, not past the label interval in either direction
- Customer text with the new date, sent from the hold
- Status per visit: Scheduled, Weather hold, Rescheduled, In progress, Done, Skipped (with reason)
Module 5
Notices and markers
Illinois and New York write down who must be told and what goes in the lawn, and a missed notice is the complaint that reaches the state.
- Neighbor record on the property: name, address, phone or email, state rule (Illinois day-before on request, New York 48-hour written)
- Notices generated with the customer's day-before text; New York versions in English and Spanish
- Fallback step: written notice left at the door when the neighbor can't be reached, with a photo
- Marker step for Illinois addresses: 4 x 5 inch white marker, 'STAY OFF TREATED SURFACE UNTIL DRY', photo per entry point
- Rule: a visit at a property with a notify-request can't close without the notice logged
Module 6
Field app application record
When a neighbor, a beekeeper or the state asks what was sprayed, the answer has to be on the visit, not in a tech's memory.
- Offline checklist: standing-water walk, containers tipped, larvicide placed (product, count, location), In2Care stations refilled
- Spray block: start and stop time, wind speed and direction, temperature, product, rate, gallons of finished mix, sq ft treated
- Zones treated and zones skipped with reason (bees on blooms, gusts, locked gate, people in the yard); no-spray zones ticked as avoided
- Applicator name, license number and Illinois certification pulled from the user profile; expired certification blocks the visit
- Photos: marker, standing water found, larvicide placement
Module 7
Event treatments
Weddings, graduation parties and outdoor corporate events are booked once, with a fixed date and no second chance.
- Event record: event date and time, venue area sq ft, tent yes/no, guest count, contact on the day
- Spray scheduled e.g. 24 to 48 hours before the event, inside the wind and rain rules, with a backup slot
- Deposit at booking, balance on completion
- If the property is on a season program, the event round is checked against the label interval from the last round
Module 8
HOA, commercial and water-edge contracts
Common areas, retention ponds and municipal work bring water, boards and permits into the job.
- Contract with sites, common-area zones, retention ponds and catch basins as assets
- Water-edge flag on any zone that touches water of the US: larvicide or adulticide quantity and location recorded for the EPA Pesticide General Permit
- Catch basin log: basin, size, briquets placed (e.g. Altosid: 1 up to 1,500 gal), date, next due within 30 days
- Monthly board report: rounds done, gallons by product, basins treated, service requests
Module 9
Billing and chemical use reporting
Rounds turn into money one by one, and chemical use has to add up by product at season end.
- Invoice per round on completion, or draw-down against the prepaid season, synced to QuickBooks or Xero
- Rain retreats and callbacks priced at zero against the original round
- Season report by product: EPA Reg. No., gallons of concentrate and finished mix, sq ft treated, by applicator
- Per-tech view: rounds per day, callbacks per 100 rounds, weather holds
The AI agents, set up for mosquito control companies

Straight answers
Mosquito control: FAQ
What software do mosquito control companies use?
Most use pest control software: GorillaDesk has a mosquito page with 14, 21 and 30-day cycles and chemical logs; FieldRoutes and PestPac suit larger pest companies that run mosquito as a service line. Public abatement districts use GIS tools like FieldSeeker. Fieldproxy is set up around your own yards, programs, label limits and state notices.
How often can you spray a yard for mosquitoes?
As often as the product's label allows at the rate you use. The Talstar TC label limits low-rate repeat sprays to once per seven days and the high rate of 1.0 fl oz per gallon to once per four weeks. Many companies run 21-day rounds, which means a rate below that label's maximum.
Can you spray for mosquitoes when it's windy?
Not above 10 mph under the Talstar TC label, and Illinois bans barrier mosquitocide applications at 10 mph or more. Record the wind on site with every application.
Does rain wash away a mosquito barrier treatment?
Mosquito Squad's FAQ says that once the spray has dried, about 30 minutes in typical conditions, rain usually does not remove it, and heavy rain before it dries usually earns a free retreat. The Talstar TC label says not to apply during rain and advises calm weather with no rain forecast for 24 hours.
Do I have to tell the neighbors before spraying a yard for mosquitoes?
Depends on the state. Illinois: abutting neighbors who ask must be told at least the day before. New York: in counties that adopted the Neighbor Notification Law, certain commercial lawn applications need 48 hours' written notice in English and Spanish.
What are Illinois' rules for residential mosquito spraying?
Certified applicators only (at least one hour of approved training, valid three years), no sprays from 16 October to 14 April or in winds of 10 mph or more, a white 4 x 5 inch 'STAY OFF TREATED SURFACE UNTIL DRY' marker at entry points, day-before notice to neighbors who ask, and no residential automatic misting systems.
Are mosquito misting systems legal?
Not in Connecticut, which banned residential pesticide misting systems in 2018, or Illinois, whose rule says no person may install or use one. Check your state before selling or servicing them.
Do mosquito companies need an NPDES permit?
Only when spray discharges to waters of the US. Under EPA's Pesticide General Permit, for-hire applicators are covered automatically and do not file a Notice of Intent, but they must follow the permit and keep records of the quantities and locations of pesticide discharged to water.
Can 'natural' mosquito sprays claim to prevent disease?
No. Minimum-risk 25(b) products, such as cedar oil and citronella blends, cannot claim to control pests that affect anyone's health, and most states still require them to be registered.
How many briquets go in a catch basin?
On the Altosid Briquets label: one per basin up to 1,500 gallons, rising to four for 4,500 to 6,000 gallons, lasting up to 30 days. Flowing water shortens that, so check and retreat.
