400 quarterly accounts is $16,000/mo on a half-full route — every route hour nets $200, and the book itself sells for 15× monthly.
Pest control is the quiet annuity of service businesses: one 25-minute quarterly visit anchors three months of revenue, chemicals cost $3 a stop, and retention runs near 90% with auto-pay. Four hundred quarterly accounts at $120 is $16,000 a month of recurring revenue on a route that is only 45% full — and route books trade at roughly 15× monthly revenue. This calculator models your accounts, pricing, and stop times into monthly recurring, route fill, net per route hour, and what the book is worth.
Pest pros use it before buying or selling a book: 400 quarterly accounts is $16k/mo on a half-full route, $200/hr on route time — and the route itself sells for 15× monthly.
Tight residential routes trade at roughly 1.25–1.75× annual recurring revenue — about 15–21× the monthly number, $240,000 for the example book — with the multiple driven by density, retention, and contract quality rather than raw account count. What raises the multiple: accounts clustered so a tech services 14+ per day, auto-pay penetration above 80%, written agreements with annual terms, low cancellation history you can document, and service notes that transfer. What cuts it: scattered geography, verbal agreements, one-time-heavy revenue mixed into the "recurring" claim, and accounts priced below market that the buyer must re-price (and lose a slice of) post-sale. Selling process: brokers and the big nationals both buy routes — the nationals pay for strategic density in their map; brokers reach the independent buyers who pay more for a full route with the seller's transition help. The buy-side version: buying a retiring operator's book at 15× monthly is cheap when those accounts slot between your existing stops — the density math prices what they do to YOUR route fill, which is worth more than the revenue alone.
Density first, then add-ons, never discount sprawl. The neighbor pitch is the highest-ROI move: every service call ends with the three adjacent homes — a stop added between two existing stops costs 10 minutes of drive, while one across town costs 40, and at $200+/hr of route value the far stop pays less than half. Referral credits ($25–50 per signed quarterly) outperform ads because they arrive pre-sold and pre-located next to existing stops. Route-fill discipline: below roughly 60% fill you have a part-time job subsidizing a truck — focus marketing inside the existing map until the route tightens. Then the add-on ladder per stop: mosquito and tick seasonal programs ($80–120/mo in season), termite monitoring ($250–400/yr), rodent exclusion projects ($500–2,500), and bed bug work ($1,000–3,000) — the quarterly route is the distribution channel for all of it, and add-ons raise revenue per stop without adding stops. Buying routes from retiring operators beats organic growth when the geography overlaps — the calculator's sale-value line prices what you should pay.
One truck, the license, and a route book — the math is unusually kind. A $20/hr tech running a $16k/mo route leaves roughly $12k/mo after wages, chemicals, and vehicle costs, which is why technicians eventually notice. The legal gate: pesticide applicator licensing is state-controlled — you need the certified applicator credential (and in most states a licensed qualifier attached to the business) before the first paying spray; the exams are passable, the violations are not. The startup path that works: work a route for 2–3 years (learn the chemistry, the calendar, and the customer conversations), get licensed, buy a used truck and the core equipment ($15–25k all-in), and seed the book with a purchased partial route plus the neighbor-pitch engine — NOT by discounting below market, because cheap accounts churn and stay cheap. Insurance: general liability plus pollution/chemical coverage — the drift claim is the industry's lawsuit. The retention spine: auto-pay, annual agreements, and a service-guarantee callback policy — free re-service between visits is cheap insurance that keeps cancellations under 10%.
