Termite treatment estimates: liquid vs. bait systems

What a good termite estimate does

A termite estimate is a technical document and a sales document at the same time. The homeowner needs to understand what you found, what you recommend, what it costs now and what it costs to keep the home protected. Many homeowners get more than one estimate, so clarity and a sound inspection report decide the job as often as price.

The stakes are high for customers. The National Pest Management Association estimates termites cause more than $6.8 billion in US property damage each year, costs not covered by homeowners insurance^[2]. That is a reason to inspect carefully and explain options well, not to pressure anyone into a same-day decision.

Inspection and measurement

1. 01

   Inspect the structure

   Check the foundation, crawl space or basement, garage, attic where accessible, and the exterior for mud tubes, damaged wood, swarmer wings and frass. Photograph every finding.

2. 02

   Identify the termite type

   Subterranean, drywood or another species. The type decides the treatment options; this guide focuses on subterranean termites.

3. 03

   Measure linear feet

   Measure the outside perimeter of the foundation, plus any interior foundation walls, piers or plumbing penetrations that need treatment.

4. 04

   Map the slab areas

   Mark attached slabs that need drilling: garage floors at the wall, porches, patios, stoops, driveways next to the house and bath traps on slab homes.

5. 05

   Note construction type

   Monolithic slab, floating slab, supported slab, crawl space or basement, and any hollow block foundations that need treating inside the voids.

6. 06

   Record conducive conditions

   Wood-to-soil contact, mulch against siding, leaking gutters or downspouts, moisture in the crawl space, stored firewood against the house.

7. 07

   Check site restrictions

   Wells, cisterns, ponds, high water tables and drainage that can restrict where and how liquid products may be applied under the label and state rules.

Measurements and construction type drive labor and product; conducive conditions drive the advice that keeps a treatment working. Both belong on the estimate.

Liquid vs. bait: an honest comparison

University of California Integrated Pest Management guidance describes liquid applications as the method most often used for subterranean termite control, applied to the soil as drenches or injections, with perimeter barriers made by professional applicators through trenching, drilling or rodding^[1]. The same guidance says bait station systems can be effective in some cases but may take several months or even years to control the problem and must be followed up with constant monitoring^[1].

Present both where both are suitable, and say which you recommend and why. Some companies also offer a combination: a targeted liquid treatment at active areas plus a bait system for ongoing protection.

How to price each method

Liquid treatments are usually priced from linear feet and drilling, because those drive labor and product:

• Linear feet of trenching and rodding around the foundation.
• Drilling: linear feet of slab or the number of drill holes, plus patching.
• Voids in block foundations, priced by linear foot of wall.
• Access adders: tight crawl spaces, finished basements and obstacles.
• Product and equipment cost, at your markup.

Bait systems are priced from installation plus monitoring:

• Number of stations, set by the perimeter and the spacing on the product label.
• Installation labor and the stations themselves.
• First-year monitoring visits and bait replacement.
• An annual monitoring and renewal price after the first year.

Whichever method, build the labor price from your billable rate and your own production times for trenching, drilling and station installation.

Renewal agreements and bonds

Termite protection is usually sold with an annual renewal agreement after the initial treatment. Spell out exactly what it covers, because customers often assume more than it does.

• Retreatment-only: if termites return, you retreat at no charge. Damage repair is not included.
• Repair agreement: retreatment plus repair of new termite damage up to a stated limit, under stated conditions. These carry more risk and need careful underwriting and wording.
• Annual inspection: included with renewal, with a written report each year.
• Customer obligations: correcting conducive conditions, notifying you before construction or landscaping changes, allowing access.
• Transfer: whether the agreement transfers to a new owner when the home is sold, and any fee.
• Exclusions: drywood termites, inaccessible areas, damage from conditions the customer was asked to fix.

Regular inspections matter whatever the method. The UC IPM guidance says regular inspections every 3 to 5 years help detect infestations before they become damaging, and homes with a history of subterranean termite problems should be inspected by a professional every several years^[1]. Annual inspections under a renewal agreement go further and are what customers are paying for.

Wood-destroying insect reports

Real estate transactions often require a wood-destroying insect (WDI or WDO) inspection report. These are a separate service with their own price, turnaround and liability.

1. Use the form your state or lender requires, and follow the state's rules on who may sign it.
2. Price the inspection as a flat fee by home size and construction type, with a rush fee if you offer same-day reports.
3. State the scope and limits: visible and accessible areas on the inspection date only.
4. Record findings with photos and keep them on file.
5. If activity is found, provide a separate treatment estimate; keep the report factual and separate from the sales proposal.

Licensing applies throughout. State laws require pest control workers to be licensed, usually after training and an exam^[3], and EPA's certification standards set rules for applicators of restricted use pesticides and for the noncertified applicators working under their supervision^[4].

Example: one slab home, two options

Example: a fictional company inspects a 1990s slab-on-grade home with active mud tubes in the garage. The foundation perimeter is 180 linear feet, with an attached garage, a front stoop and a rear patio, all needing drilling along the house. There is no well on the property. Option one is a liquid treatment: 180 linear feet of trenching and rodding plus 64 linear feet of drilling and patching, priced from the company's per-foot rates, with an annual retreatment renewal. Option two is a bait system: 20 stations around the perimeter at label spacing, installation and first-year monitoring, then an annual monitoring renewal. The estimate shows photos of the mud tubes, a diagram of the measurements and drilling areas, both prices, both renewal terms, and three conducive conditions for the homeowner to fix, including mulch against the siding. The technician recommends the liquid treatment because activity is present and the customer wants prompt control, and notes that baits remain a reasonable choice.

Common estimating mistakes

• Measuring only the outside perimeter and missing interior foundation walls, piers or plumbing penetrations on crawl space homes.
• Forgetting attached slabs, such as stoops and patios, that need drilling; they add labor, patching and product.
• Quoting a liquid treatment without checking for wells, cisterns or drainage that limit where product can go.
• Selling a renewal agreement without explaining whether it covers repairs or retreatment only.
• Promising a bait system will clear an active infestation quickly, which the evidence does not support.
• Leaving conducive conditions off the estimate, so the customer never fixes the moisture or wood-to-soil contact that invited termites.

Review completed jobs against estimates each quarter: actual linear feet, drilling footage, product used and labor hours. Adjust your per-foot rates and production times from that record rather than from memory.

Presenting the estimate

Lead with the findings and the photos, then the options and prices, then the renewal terms and the customer's responsibilities. Avoid fear-based language. If the customer wants to think it over or get another estimate, give them a written copy and a date by which the price holds.
