Pest Control Deductions: The Chemicals, the Trucks, the License Renewals, the Termite Bond You Can't Reserve For, and the Route You Bought

Pest control is a route business: recurring customers, a truck with a tank and a sprayer, chemicals bought by the drum, and a technician who must be certified, or work under a certified operator, to use them. The deductions follow — supplies, vehicles, equipment, licensing, and the customer list itself when a route is bought — with two issues specific to the trade: termite bonds that obligate the company to future repairs it cannot deduct in advance, and annual contracts paid up front that are income before the service is performed.

Chemicals, bait, and consumables

Pesticides, termiticides, bait stations, rodenticides, gloves, masks, and application supplies are materials and supplies — deducted in the year they are used, or in the year bought for incidental supplies kept without consumption records and for items costing $2,500 or less per invoice or item under the de minimis safe harbor election. A company that sells products to customers (a do-it-yourself bait kit) holds inventory for those items — or, under the small-business exception, treats them as non-incidental supplies deducted in the year sold. Chemical disposal fees, respirator fit testing, and safety data sheet subscriptions are ordinary expenses.

Trucks, rigs, and equipment

Service trucks fitted with spray tanks, pumps, and reels are the main capital asset. A truck rated over 6,000 pounds gross vehicle weight escapes the passenger-vehicle depreciation caps and qualifies for Section 179 and 100 percent bonus depreciation (for trucks acquired after January 19, 2025); the tank, pump, and reel installation is equipment depreciated with it. Because the trucks carry high operating costs and are used almost entirely for work, the actual-expense method generally beats the standard mileage rate; a log still establishes business use. Termite treatment rigs, foggers, drills for slab injection, and bait station tools are equipment; moisture meters and inspection cameras are usually under the $2,500 de minimis safe harbor threshold.

Vehicle wraps are advertising, deductible when applied. Fuel, insurance, repairs, and tires follow the vehicles.

Licensing and training

The company's state pest control license, the operator certifications and technician identification cards or applicator licenses the state requires (in Florida, a $300 license per business location and $10 per employee identification card), continuing education to maintain them, and exam fees for new categories (termite, lawn, fumigation — $300 per category for Florida's certified operator exam) are deductible — renewals as paid, initial licensing for a new business as a start-up cost. Training on new products and safety courses is education that maintains skills in the current business.

Termite bonds and the reserve problem

A termite bond promises to re-treat and, under a repair bond, to repair damage if termites return. The company's obligation is real and often funded by a reserve in the books — but a reserve is not deductible for tax. Repair and re-treatment costs are deducted when the work is performed and paid. An accrual-method company can deduct a liability only when the all-events test is met and economic performance occurs, which for a repair the company performs means when the repair is done, and for a damage claim settled in cash means when it is paid. Bond renewal fees charged to customers are income when received for a cash-method company; an accrual-method company includes them when received unless it elects the advance-payment deferral, which pushes the unearned portion at most into the following tax year.

Annual contracts paid in advance

Quarterly service plans billed annually, prepaid lawn programs, and termite bond renewals are advance payments. A cash-method company reports them when received. An accrual-method company that elects the advance-payment deferral includes the portion earned in the year of receipt (or, if it has an applicable financial statement, the portion recognized there) and the rest in the following year — never later. Heavy January renewals produce a first-quarter income spike for a cash-method company; an accrual-method company that defers spreads most of that income across the service year.

Buying a route

A purchased route — a customer list with recurring contracts — is a Section 197 intangible, amortized over 15 years regardless of how long the customers stay. The purchase price allocation should separate the customer list, any noncompete from the seller (also 15-year, ordinary income to the seller), equipment and trucks (depreciable, often expensed), and chemical inventory (deducted as used). Buying the seller's corporate stock instead of its assets leaves the old basis in place and gives the buyer no new amortization, unless the parties make a section 338(h)(10) or 336(e) election; buying all the interests in a single-member LLC is treated as buying its assets.

Payroll, uniforms, and software

Technicians are employees — on your schedule, in your trucks, using your products. Uniforms with the company logo are deductible; the boots and jeans under them are not. Route management and scheduling software, GPS tracking, and the customer portal are subscriptions deducted as paid.

Florida sales tax

Florida taxes nonresidential building pest control services: a treatment for an office, a warehouse, or a restaurant is taxable at 6 percent plus any county surtax, and the company collects and remits. Pest control for residential facilities — single-family homes, apartments, condominiums, and their common areas — is not taxable, and neither is lawn spraying, residential or commercial. A route with both must separate the invoices, and a company that sells products with a service collects tax on the products.

Worked example. A pest control company runs six trucks on residential and commercial routes. It buys two new service trucks at $52,000 each with $9,000 of rig installation per truck; all are over 6,000 pounds and deducted in full under bonus depreciation. Chemicals for the year total $84,000 of supplies. It buys a competitor's residential route for $180,000 — allocated $140,000 to the customer list (15-year amortization), $25,000 to two used trucks (expensed), $10,000 to a noncompete (15-year), and $5,000 to chemicals on hand. Its termite repair bond reserve is $40,000 in the books; it deducts the $12,000 of actual repairs performed that year. Forty percent of its revenue is pest control for commercial buildings, on which it collects Florida sales tax.
