Pest control is one of the few service trades where the vehicle is also the delivery system. The technician carries a tank, a pump, hoses, a reel, personal protective equipment and a licence file, then drives a route that stops every eight to fifteen minutes. That profile is the opposite of a delivery route, and it is the reason a growing number of applicator businesses are running electric cargo tricycles instead of a second van. This guide works through what actually decides whether the platform fits: the chemical payload, the washdown regime, the route-time arithmetic, and the order terms you should lock before committing a fleet.
Why a Treatment Route Is Not a Delivery Route
The first mistake in specifying an applicator vehicle is to borrow the assumptions from parcel or food delivery. The duty cycles look similar on paper and diverge almost immediately in practice. Five differences decide the build. If your business already runs grounds work, the route logic in our landscaping trike guide is the closest neighbour to this one, and the call-out differences are worth reading side by side:
- Stops are fixed-time, not fixed-distance. A delivery round is measured in kilometres. A treatment round is measured in minutes-on-site multiplied by stops. The vehicle spends far more time parked and open than it does moving.
- The payload is a tank, not boxes. Liquid moves and sloshes. A part-full tank on a three-wheeled platform behaves differently from a part-full crate load, and the mounting has to account for it.
- The route ends in a washdown, not a handover. Chemical residue, hose water and tank rinse are part of every working day. Corrosion protection is a specification item, not a nice-to-have.
- Weight is concentrated, not distributed. A 100 L tank is roughly 100 kg in one footprint. Where that footprint sits on the chassis decides stability far more than the total payload figure does.
- Equipment is permanently mounted. A pump, reel and hose set stays on the vehicle. That changes serviceability requirements: you need access to the pump without dismantling the cargo body.
The Payload Envelope: What the Platform Actually Carries
The cargo e-tricycle platform is rated at 300 kg (EU) / 500 kg (non-EU), with a box volume of 150–500 L depending on the build tier. The full breakdown of how that rating interacts with tires, brakes and frame is in our payload capacity guide. That envelope accommodates a realistic applicator load with headroom, provided you do the arithmetic before the order rather than after.
A representative single-technician load breaks down as follows. A 100 L tank at full fill is about 100 kg. The pump, reel and 30–50 m of hose add 15–25 kg. A handheld sprayer and spare lance add 5–8 kg. Personal protective equipment, a spill kit and a first-aid kit add 8–12 kg. Reference documents and a tablet add 2–3 kg. That lands between 130 kg and 150 kg — comfortably inside the EU rating with roughly half the envelope in reserve.
Two limits bind before the total payload figure does. The first is axle and box distribution: a single 100 kg tank placed at the rear of an open box shifts the centre of gravity backwards on a delta-layout trike, and that is a stability question, not a capacity question. The second is tank baffling. An unbaffled part-full tank puts a moving load on the chassis at every corner and stop; a baffled or compartmented tank removes most of that behaviour. If a supplier cannot tell you how the tank mounts and whether it is baffled, they have not built for this trade.
Tank, Pump and the 12-Volt Question
The traction battery and the application pump are two independent systems, and confusing them is the most common specification error in this segment. The platform's traction pack is 60V 32Ah NMC or 72V 40Ah LFP, feeding a 800W / 1000W / 1200W brushless hub motor with differential. Application pumps in this trade are almost always 12 V diaphragm units drawing 5–10 A.
That means one of three arrangements, and you should choose deliberately:
- Separate 12 V battery for the pump. The pump runs independently of traction range. You recharge a small battery each night. This is the simplest and the most common, and it protects traction range absolutely.
- DC-DC converter from the traction pack. Draw is small against a 1,920 Wh (60V 32Ah) or 2,880 Wh (72V 40Ah) pack, so range impact over a shift is modest. You carry fewer batteries, but the pump is now on the same system that moves the vehicle.
- Pump driven from an independent circuit with its own isolation. Needed where the pump duty is heavy, such as a two-technician build running two lances.
Tell your supplier which arrangement you want before the BOM is frozen. Retrofitting a converter or a second battery bay after delivery usually means drilling and rewiring a finished powder-coated frame, which is exactly where rust starts.
Corrosion, Washdown and Why the Paint Spec Matters
Chemical application is an abrasive environment for metal. The relevant specification is the frame treatment: steel tube chassis with heavy-duty e-coat plus powder coat. That two-stage process is what separates a vehicle that survives several seasons of daily rinse-down from one that shows surface rust at the welds within a year.
Three items worth confirming in writing:
- Box material and finish. Aluminium sheet or steel with drop-sides is standard. For a washdown regime, aluminium avoids the corrosion question at the panel level entirely, at a modest cost premium.
- Electrical ingress protection. The motor is rated IP65. Controllers are typically IP54–65 depending on potting. Both are discussed in more detail in our safety features guide. Confirm the rating on the specific controller in your build, because a pressure washer and a garden hose are not the same test.
- Drainage and mounting hardware. Stainless fasteners at the tank mount and a box floor that drains rather than pools. Both are cheap at the factory and expensive in the field.
One operational note that belongs in the spec conversation: pressure washing electronics at close range is the fastest way to void a warranty and to introduce intermittent faults that are almost impossible to diagnose later. A low-pressure rinse with the controller bay closed is the correct procedure, and it should be written into the vehicle's care instructions on day one. Contractors running a similar daily-exposure duty cycle should also read our field service fleet guide.
Route-Time Arithmetic: Where a Trike Wins and Where It Does Not
The economic case rests on time and cost per stop, not on the purchase price alone. Using the platform's real figures — 50–80 km loaded range at 200 kg, 25–35 km/h top speed, and a 6–10 hour charge at 5A — the arithmetic is straightforward.
A residential treatment round covering 15 km with 18 stops is roughly 35 minutes of travel plus 2.5 to 4 hours on site. Total duty is under five hours, well inside a single charge with margin. The 25–35 km/h governor is settable at 25 / 35 / 40 km/h, and in urban residential work the low setting is usually the right one — the time saving from a higher limit is negligible against the stop time, and a governed platform is easier to defend in a residential complaint. For a comparable circuit-based view of a low-speed fleet, see our public works trike guide.
Two constraints matter more than range. First, the cargo platform at 150–220 kg unladen is not a vehicle you thread through a side gate the way you would a hand cart. Where a property has a narrow access point, the walk from the vehicle is part of the route time and needs to be in the estimate. Second, the charge window is 6–10 hours on the standard 5A unit. One vehicle covers one working shift per day on overnight charging. A business running two shifts, or a single vehicle covering both a morning and an evening round, needs either a second platform or a higher-current charging arrangement — there is no way to charge the pack meaningfully inside a lunch break. The full shift-planning method is in our fleet charging guide.
Fleet Math: Two Units vs a Second Van
The comparison a fleet owner actually makes is trike versus a second light commercial van. The cost is not the whole story; four other numbers usually decide it.
- Purchase cost. The three tiers sit at $1,250–1,550 (Light, 800W / 60V 32Ah NMC), $1,580–1,880 (Standard, 1000W / 60V 32Ah NMC) and $1,880–2,250 (Heavy-Duty, 1200W / 72V 40Ah LFP) FOB. Two trikes land well below one new van before any fitting.
- Running cost. Charging from a standard outlet at 5A is a domestic-scale electrical load. There is no fuel, and the maintenance surface is smaller: fewer parts, no engine service schedule.
- Licence and access. The regulatory position varies by market and by vehicle class, so this must be checked for your jurisdiction rather than assumed. The practical advantage is that a narrow, low-speed platform reaches restricted residential and pedestrian areas that a van cannot serve.
- Brand impression. For residential and municipal work in particular, arriving on a quiet, low-speed platform reads differently from arriving in a commercial van. Several operators report this as a real commercial factor rather than a soft one.
Where the trike does not replace a van: long multi-site contracts with highway travel between sites, high-volume bulk chemical delivery, or any route where the total daily distance routinely exceeds the loaded range envelope. Be honest about which of your rounds those are, and keep a van for them.
Specifying the Vehicle: A Checklist
Bring these to any supplier conversation, and expect written answers rather than verbal ones.
| Item | What to specify | Why it matters |
|---|---|---|
| Motor / drivetrain | 800W, 1000W or 1200W hub with differential | The differential matters on tight residential turns; without it the outer rear tyre scrubs |
| Battery | 60V 32Ah NMC or 72V 40Ah LFP | LFP is the right choice for daily deep cycling and hot-climate duty |
| Payload | 300 kg (EU) / 500 kg (non-EU) | Confirm the certified rating, not a marketing figure |
| Box volume | 150–500 L, with drop-sides | Drop-sides let you load and rinse the tank without lifting it |
| Frame finish | E-coat plus powder coat | The single biggest determinant of corrosion life in a washdown regime |
| Brakes | Hydraulic disc front, dual drum rear, parking brake | A parking brake is not optional on a gradient with a part-full tank |
| Tires | 3.00-12 front / 3.75-12 rear dual | Confirm load-rated replacements are available as a stocked spare — see our cargo trike tires guide |
| Charging | 5A standard, 6–10 h | Size the charge window around your shift pattern before ordering |
Order Terms and Programme Risk
The commercial structure is consistent across the platform: MOQ 50 units for a standard order, 15–30 days production, and 30–45 days for a first order that carries custom branding or a bespoke tank mount. Budget the longer figure for your first unit, not the shorter one.
Three programme risks are worth managing explicitly. First, sample before volume: specify and receive one representative unit, fit your actual tank and pump to it, and run two weeks of real routes before releasing the balance. Second, confirm the spare-parts pipeline for the wear items — tires in the correct sizes, brake consumables, controller and pump-adjacent electricals. A fleet built on a platform with no stocked spares is a fleet with an expiration date — the wear-item list in our spare parts guide is the place to start. Third, get the quality documentation with the order. A supplier running IQC, IPQC and OQC gates has the records; ask for the inspection evidence, not just the certificate.
Finally, request the certification pack for your destination market at quotation stage. The compliance route determines what you can legally register and operate, and it is far cheaper to resolve at order time than after the container has landed.
Frequently Asked Questions
How much chemical can a pest control e-tricycle actually carry?
The platform is rated at 300 kg (EU) / 500 kg (non-EU). A realistic single-technician load — a 100 L tank, pump, reel, hose, PPE and paperwork — lands around 130–150 kg, leaving roughly half the envelope in reserve. The binding constraints are usually tank baffling and where the tank footprint sits on the chassis, not the total rating.
Can I run the spray pump from the traction battery?
Yes, via a DC-DC converter. A 12 V diaphragm pump drawing 5–10 A is a small load against a 1,920 Wh or 2,880 Wh pack. The alternative is a separate 12 V pump battery, which keeps the pump off the traction system entirely. Decide before the BOM is frozen, because retrofits mean drilling a finished frame.
How many properties can one charge cover?
Loaded range is 50–80 km at 200 kg. A residential round of 15 km with 18 stops uses well under half a pack. The real limit is the 6–10 hour charge window: one vehicle supports one working shift per day, and a two-round business needs a second platform or a higher-current charging setup.
Will the vehicle rust?
Not within a normal service life if you specify correctly. The frame is steel tube with e-coat plus powder coat, the motor is IP65, and aluminium box panels remove the corrosion question at panel level. The two failure modes to avoid are pressure-washing the controller bay and letting unsealed mounting hardware sit wet.
