Mosquito and tick season planning

Why customers care about this season

For most customers, mosquitoes and ticks are first a nuisance: bites, children who will not play outside and evenings spent indoors. For a growing share, they are also a health worry. Pest control companies are in a good position to help, but the conversation needs care. You can reduce mosquito and tick numbers around a property. You cannot guarantee that nobody will be bitten or fall ill, and you should never suggest otherwise.

What the CDC data shows

CDC describes West Nile virus as the leading cause of mosquito-borne disease in the contiguous United States, spread mostly during mosquito season, which starts in the summer and continues through fall, typically June through October^[1]. Most people infected do not develop symptoms^[1], which is one reason customers underestimate it.

Ticks carry a larger reported burden. More than 80,000 Lyme disease cases are reported to CDC each year by states and jurisdictions, and an estimate based on insurance claims suggests about 476,000 people are treated for Lyme disease each year^[2]. The gap between the two numbers is a reminder that reported cases understate how common tick-borne illness is.

Season start by region

Treat this table as a starting point. Season timing moves from year to year with temperature and rainfall: a warm, wet spring can bring mosquitoes weeks earlier than usual, and a mild winter can leave more ticks active in early spring. Build some flexibility into your first visit dates rather than fixing them in January. Your state health department and local mosquito control district publish surveillance updates that tell you when activity is rising in your area, and your own call records show when customers start asking.

Build a program, not a spray

1. 01

   Inspect the property

   Walk the yard for standing water, clogged gutters, containers, birdbaths, tarps and low spots. For ticks, look at leaf litter, tall grass, wood piles and the edges where lawn meets woods.

2. 02

   Reduce the sources

   Tip and remove containers, clear gutters and advise on drainage. For ticks, recommend keeping grass short, clearing leaf litter and creating a dry barrier between lawn and woods.

3. 03

   Treat resting and harborage areas

   Apply products to the shaded vegetation where adult mosquitoes rest and to tick habitat at the yard edges, following label directions.

4. 04

   Treat water that cannot be removed

   Use larvicides where the label and your license allow, such as in drains or ornamental water features.

5. 05

   Return on schedule

   Revisit on a fixed interval set by the product label and local pressure, re-inspect and leave a short service note.

Scheduling the routes

Recurring programs live or die on routing. Group customers by neighborhood and assign each zone a fixed weekday so visits land on the same interval. Build in weather rules: most labels restrict application in rain, high wind or before heavy rainfall, so set a standard reschedule window and tell customers what it is. Leave capacity for event treatments before outdoor parties and weddings, and price them separately so they do not crowd out program visits.

Staff for the peak. Pest control employment rose from 147,900 in January 2025 to 159,100 in August 2025^[3], and evening and weekend work is common in the trade^[4]. If you add seasonal technicians for mosquito routes, start their training and licensing early enough that they are ready when the first program visits are due.

Product rotation and resistance

• Group the products you use by mode of action and plan rotations across the season rather than repeating one product.
• Combine adulticides with larval control and source reduction so you are not relying on one tool.
• Record product, rate, location and weather for every application so you can see patterns when results fall off.
• Respect pollinator and aquatic label restrictions, such as avoiding blooming plants and keeping drift away from water.
• Talk to your distributor or state extension service about local resistance reports before the season.

Licensing and compliance

Most US states require licensing for workers who apply pesticides^[5]. Restricted use products carry stricter rules: about one million applicators are certified to use restricted use pesticides, alongside an estimated 930,000 noncertified applicators^[6], and noncertified applicators must be trained and work under a certified applicator^[7]. Check the license category each technician needs for mosquito and tick work in your state, especially for larvicide applications in water, and keep records in the format your state requires.

Talking to customers

• Explain what the customer must do between visits: empty containers, keep grass short, clear leaf litter.
• Tell pet owners how long to keep animals off treated areas, using the label instructions.
• Explain the weather reschedule rule before the first visit.
• Point customers with health questions to their doctor and to public health sources, not to your technicians.

Example: launching a tick-first program

Example (fictional): a pest control company in a wooded suburb of the Northeast finds that customer calls about ticks start weeks before calls about mosquitoes. It launches a combined program with the first visit focused on tick habitat in April, adds mosquito treatments from June, and ends with a fall tick visit. Technicians carry a short inspection checklist and photograph source-reduction items for the customer. The office books each new customer into the zone that matches their street and confirms the weather rule in the welcome message.

Pricing the program

Mosquito and tick programs are usually sold as a set number of visits across the season. Price them on what each visit really costs: drive time within the zone, treatment time based on property size and habitat, product cost and the inspection and note at each stop. Larger lots with long wooded edges take far more time than small suburban yards, so use size or habitat tiers rather than one price for everyone. Sell event treatments separately with a lead time, and make the program terms clear on weather delays, skipped visits and cancellations. A written agreement with the visit schedule avoids most disputes.

Training technicians for the season

• Identify common mosquito breeding sites and tick habitat on real properties during ride-alongs.
• Read and explain each product label, including weather limits, pollinator protection and re-entry instructions.
• Calibrate and maintain backpack and power sprayers before the first visit.
• Practice the customer conversation, including what the program does and does not promise.
• Use personal protective equipment as the label requires, and check for ticks after each shift.

Technicians are the main source of customer trust in these programs. A technician who points out a clogged gutter or a pile of leaf litter, and explains why it matters, makes the program feel like a service rather than a spray.

What to measure

• Program sign-ups by month, and the date the first sign-up arrived in each zone.
• Visits completed on interval versus late.
• Customer callbacks for activity between visits, by technician and zone.
• Weather reschedules and how quickly they were completed.
• Renewal rate for next season.

Review these each fall and set next year's start dates and staffing from them. For the full year of pest work, see the pest seasonal calendar, and for adjusting staffing and ads to forecasts, see weather-based marketing.
