Pyrethroid resistance
UK bed bug populations carrying the kdr genetic mutation that renders standard pyrethroid spray ineffective. The dominant chemistry of the last thirty years no longer works at label rates.
Vesper
Hotels & hospitality
Bed bugs,
Bed bugs,
before the guest review.
Continuous LoRaWAN sensors at room-level harbourage conditions, plus event-based trap detection. Active dispatch on every breach, with zero-COSHH chemistry that does not need a four-hour re-entry interval. The room is not blocked while the work is done.

Why hotels, specifically
The bed bug problem, in numbers.
Three numbers that move bed bug management from a nuisance line item into a board-level commercial concern.
£3,200 – 6,400
Revenue cost per incident
Direct revenue loss from a single undetected bed bug incident in a 200-room hotel — six rooms blocked for six weeks, plus compensation. Before reputational impact via TripAdvisor.
65 – 68%
Year-on-year case growth
Reported bed bug case volume increases in 2023 and 2024 — not population growth, treatment failure. The same chemistry is being applied; the same chemistry is no longer working.
The Vesper approach
Detect at harbourage. Treat at first event.
The bed bug is at the seam, the head-board edge, and the skirting return long before a guest sees it. Our sensor plan starts where the population establishes — not where it becomes visible.
Dragino LHT65N — environmental sensor
Placed at room-level harbourage conditions. Bed bugs proliferate at 20–30°C and 70–90% relative humidity. The sensor detects the conditions before the population.
Spotta Bed Pod — event detection
Deployed at one pod per three rooms in high-risk zones. A single catch overrides the score and dispatches immediately — there is no false-positive cost we'd choose to bear.
Private LoRaWAN gateway
Single gateway on the back-of-house network covers an entire property. AES-128 encrypted radio. No SIMs in the rooms, no monthly data fee per device.
72-hour Harbourage Risk Score
The composite per-room score weighs temperature, humidity, trap events, and seasonality. Score > 7 sustained for 72h triggers proactive treatment.

What changes on day one
Five things Vesper does that an analog contract doesn't.
1
Detects before a guest doesContinuous environmental monitoring identifies harbourage conditions weeks before a guest reports a bite or sees a sign. The alert reaches your operations team, not your front desk.
2
Treats without taking the room out of serviceZero-COSHH chemistry has no four-hour re-entry interval. The room can be re-let immediately on treatment close. No "treatment notice" left for housekeeping.
3
Dispatches on the data, not the calendarQuarterly contracts visit on a fixed cadence regardless of risk. Vesper visits when the score breaches or a trap fires — and the rest of the time, sensors do the watching.
4
Produces an audit trail that survives a TripAdvisor incidentEvery reading and every treatment hashed and timestamped. If an incident reaches social media, the documented response is already in the chain — not reconstructed afterwards.
5
Supports the insurer conversationUK commercial insurers increasingly require documented pest control programmes as a condition of cover. The Vesper compliance pack is structured for that conversation.
Regulatory context
Statutory pest-control obligations under the Food Safety Act 1990, the Health and Safety at Work etc. Act 1974, and the COSHH Regulations 2002 remain with the operator. Vesper provides continuous monitoring and documented treatment evidence to support those obligations; it does not discharge them.
