Pest control businesses have a cost structure that rewards careful tracking. Chemical costs, vehicle expenses, and licensing fees are all deductible, but the vehicle deduction alone can account for $10,000-$20,000 per year per vehicle, making it the single most valuable line item to document properly.

✓Key takeaway

Major deduction categories for pest control businesses:

Chemicals and supplies (deducted when purchased or used):

Pesticides, insecticides, herbicides, rodenticides
Bait stations, traps, monitoring devices
Spray tanks, applicator equipment
Personal protective equipment (respirators, gloves, suits, boots)
Safety data sheet (SDS) binders and required documentation

Vehicle expenses (the largest deduction for most operators):

Standard mileage rate: 70 cents/mile (2025) for business use
Actual expense method: fuel, insurance, maintenance, depreciation, tolls
For dedicated business vehicles (no personal use): 100% deductible under either method
For vehicles with GVWR over 6,000 lbs: full Section 179 deduction in year of purchase (up to $2,500,000 under OBBBA, for 2025+)

Equipment (Section 179 or de minimis safe harbor):

Backpack sprayers ($150-$500 each): de minimis safe harbor
Power sprayers ($1,000-$5,000): de minimis or Section 179
Thermal foggers ($200-$800): de minimis safe harbor
Moisture meters, thermal imaging cameras ($200-$2,500): de minimis safe harbor
Ladders, crawl space gear, attic access equipment
Tablets/phones for route management software

Licensing and compliance:

State pesticide applicator license fees
Continuing education requirements (CEU courses)
Business license and liability insurance
Workers’ comp insurance
EPA registration fees (if applicable)
Background check fees (some states require for technicians)

Technology and marketing:

Route optimization software (ServiceTitan, PestRoutes, FieldRoutes)
CRM and scheduling systems
Website and local SEO
Google Ads and local service ads (Google Guaranteed)
Wrapped vehicle graphics (deductible as advertising, not vehicle expense)

How does the vehicle deduction compare between methods?

Hypothetical example

Round numbers. A pest control operator drives a dedicated work van (no personal use) for 25,000 business miles per year.

Standard mileage method:

25,000 miles x $0.70 = $17,500 deduction
Plus tolls and parking: $500
Total: $18,000

Actual expense method:

Fuel ($4/gallon, 15 MPG): $6,667
Insurance: $2,400
Maintenance and repairs: $3,000
Registration: $200
Vehicle depreciation (5-year MACRS on $40,000 van): $8,000 (or full Section 179 in Year 1)
Total: $20,267

In this example, the actual expense method produces a larger deduction. However, the standard mileage method is simpler and does not require tracking every fuel purchase and repair receipt.

Key rule: If using the standard mileage method, the election must be made in the first year the vehicle is placed in service. If Section 179 or bonus depreciation is claimed in Year 1, the vehicle is locked into the actual expense method for its entire life. Since Section 179 on a $40,000 van produces a $40,000 first-year deduction (vs. $17,500 from mileage), most pest control operators choose actual expense + Section 179.
