Chemistry you can leave in a care home
InsectoSec DE and PelGar Sumilarv 0.5G — both GB BPR authorised, both carry zero COSHH classification, and a mechanical kill cannot be out-evolved.

Zero-toxicity IoT pest management, now live across the UK
Pest management,
Pest management,
continuously accountable.
LoRaWAN environmental sensors paired with zero-COSHH chemistry and a certified response network. Every reading and every treatment time-stamped, SHA-256 hashed, and compiled into an audit-ready compliance record — built automatically.
Continuous, hashed evidence also supports conversations with your insurer and your regulator — the documented due diligence that quarterly paperwork cannot demonstrate.

Why GreenTech
Built for accountability.
Not just attendance.
A quarterly visit covers 0.05% of your year. We cover the other 99.95% with continuous evidence — designed to support conversations with insurers, inspectors, and — if it comes to it — a court.
Continuous evidence, not quarterly paperwork
LoRaWAN sensors at key harbourage sites report every 15 minutes. A composite Harbourage Risk Score runs on a 72-hour rolling window, and dispatch fires on the data — not the calendar.
An audit trail that stands up
Every reading and every treatment SHA-256 hashed, GPS-stamped, and compiled into a CQC- and HACCP-ready pack. One click to export. No reconstruction.
Who we work with
A product for every estate.
Three institutional products, plus a purpose-built student accommodation variant. Each with its own sensor plan, dispatch SLA, and reporting cadence.
Vesper for Hotels
Bed bug detection and eradication for hotel estates, without the guest disruption. Environmental sensors at harbourage conditions plus event-based trap detection across guest floors and back-of-house, with a certified technician dispatched inside SLA on any breach.
- 20–30 sensors per site at key harbourage points

How it works
Four steps to a traceable record.
Sensors, scoring, dispatch, and compliance — one stack from survey through to inspector-ready evidence.
STEP 01
Site audit
Our engineers walk your estate and identify the harbourage points that matter — risers, voids, skirting runs, sentinel rooms — then design a sensor plan matched to your sector and size.
STEP 02
Install & monitor
LoRaWAN sensors go in at the critical points and stream temperature, humidity, CO₂, and trap events into GreenTech OS every 15 minutes. Harbourage thresholds tuned per asset.
STEP 03
Score & dispatch
A composite Harbourage Risk Score runs on a 72-hour rolling window. Score breach or trap catch triggers a certified, BPCA-qualified technician inside SLA — with DE and Sumilarv, not pyrethroids.
STEP 04
One compliance pack
Every treatment closed with a SHA-256 chain of custody. CQC Reg 12/15 pack, HACCP CCP records, monthly risk report — all exportable, all audit-ready, in a single dashboard.
The safest estate is the one with a live record.
