SCIENCE

Why diatomaceous earth cannot develop resistance

A binding-site target can mutate. A physical edge cannot. A first-principles look at why mechanical desiccation is a structurally different category of pest control chemistry.

REGULATION

The CQC Reg 12 pest-finding cascade: anatomy of a £250K cost

From the inspector's note to the action plan, the public report, the occupancy hit, and the local-authority placement decision. Why a single Regulation 12 finding moves a care home onto a different financial trajectory.

EVIDENCE

Continuous vs quarterly: the 8,760-reading argument, in numbers

Four paper entries per year. Eight thousand seven hundred and sixty continuous readings. The same site, two operating models, and an audit trail that survives different forms of scrutiny.

SECTOR

The 16-week PBSA void: what the Harbourage score sees

Heat without ventilation. Stagnant water systems. Empty kitchens. The summer void is when the harbourage develops, and a sensor plan that ignores it loses three months of data per year.

REGULATION

The s.21 due-diligence defence in pest-related FSA prosecutions

What "all reasonable precautions" looks like in the Magistrates' Court. The role of the site logbook, what it has to contain, and where digital records have been admitted in lieu of paper ones.

SCIENCE

Pyriproxyfen at 90 days: how an IGR works in a colony

An adulticide kills the visible. A juvenile hormone analogue prevents the next generation from reaching adulthood. The arithmetic of pairing the two, and why colony collapse takes the time it takes.

EVIDENCE

What SHA-256 admissibility actually requires

The hash function is not the hard part. The capture, the timestamp source, the chain integrity, and the witness-of-record evidence are. A primer on what makes a digital chain of custody hold up.

SECTOR

The kitchen void: why CO₂ is the first signal

A cockroach population doesn't surface; it respires. Why under-equipment CO₂ elevation precedes visible activity by weeks, and what it means for a HACCP-based monitoring plan.

REGULATION

GB BPR after Brexit: what's authorised, what isn't

Why some perfectly legal EU actives still cannot be deployed commercially in Great Britain. A review of the regulatory landscape, the active substances in question, and what GreenTech does about it.
