Cockroaches in Restaurants: What a Health Inspection Really Checks, and How to Avoid an Administrative Closure

The scenario comes round every autumn, in exactly the same words. A restaurateur calls us on a Thursday evening: the DDPP came by during the day, the inspector noted "presence of German cockroaches in the preparation area" and "pest control plan not formalised". The report announces administrative follow-up. The restaurant is still trading, but not for much longer if nothing changes.

The first reaction is almost always the same: "but we've got a pest control contract". That's true — and that's precisely the misunderstanding. A contract is worthless if it doesn't produce usable written records. A health inspection doesn't penalise the existence of an insect in a 1970s building connected to a sewer network: it penalises the absence of demonstrable control of the risk.

In other words, the question put to the operator isn't "do you have cockroaches?" but "what do you know about your situation, since when, and what have you done about it?". This article sets out what an inspector actually looks at, the non-compliances that tip a report towards closure, and the file to assemble before the visit rather than after.

The trigger for a closure is never the number of insects seen. It's the combination of three factors: presence in a food contact area, the absence of monitoring documentation, and the operator's inability to date the start of the problem. An establishment that can produce a dated trap log, a root cause analysis and a recent intervention invoice falls into a completely different administrative category.

The regulatory framework, in plain terms

The legal basis rests on two European texts transposed into French law and enforced by State services.

The summary fits in one sentence: the professional is responsible for the food safety of the products they place on the market, and must be able to prove it. That's the principle of self-monitoring. The inspector isn't there to do the job for you, they're there to verify that the job exists.

Since 2017, the results of these inspections have been published on the French Ministry of Agriculture's Alim'confiance platform, with four rating levels: "very satisfactory", "satisfactory", "needs improvement", "urgent corrective action required". The lowest level is public, and a customer can look it up before booking. So the stakes are no longer purely administrative: they're commercial.

What the inspector looks at, in order

Inspections in commercial catering follow a checklist. On the pest side, attention follows a fairly predictable sequence.

1. The signs, before the insects

An experienced inspector doesn't look for a live cockroach out in the open — Blattella germanica avoids light, it hides. They look for traces:

• droppings: small black specks the size of a grain of ground pepper, typically at the top corners of cupboards, on hinges, along cable runs;
• exuviae: translucent shed skins piled up in corners;
• egg cases (oothecae): brown capsules 6 to 8 mm long, glued under worktops, behind the legs of stainless steel units;
• smell: an established population gives off a characteristic acrid odour, noticeable when opening a cupboard that's been closed for several days.

The areas systematically inspected: behind the dishwasher, the base of the coffee machine, the fridge motor, cold room seals, service ducts, the bin store, floor gullies, the suspended ceiling in the wash-up area.

2. The pest control plan

This is the central document. It must contain:

• a site plan showing the numbered position of each device (glue traps, rodent bait stations, UV units);
• the inspection frequency for those devices;
• the name of the contractor or the in-house procedure;
• the safety data sheets and marketing authorisations for the products used;
• the dated and signed intervention reports, including catch records.

A plan that exists but whose traps haven't been checked for four months is just as clear a non-compliance as no plan at all. That's the most common weak point: the devices are installed, nobody reads them.

3. Structural conditions

Chemical treatment never makes up for a permeable building. Inspectors note:

• unsealed pipe penetrations under sinks and behind ranges;
• dry floor traps, a direct motorway from the sewer network;
• service doors with no sealing door bottom;
• equipment fixed to the floor with no way to clean underneath;
• floor storage of delivery boxes — the number one route by which cockroaches enter a kitchen.

4. End-of-service hygiene

A thorough overnight clean, recorded on a cleaning and disinfection schedule with dilutions and frequencies, weighs heavily in the assessment. An inspector who sees baked-on grease under the hobs immediately understands why the baits aren't working: the insect has something better to eat.

The five mistakes that turn a warning into a closure

After several years of emergency post-inspection call-outs, the list of causes is short and repetitive.

1. Spraying an off-the-shelf "knockdown" insecticide before the visit. This is the worst possible decision. Repellent aerosols scatter the population, push it into partition walls, service ducts and the neighbours' premises, and render bait gels ineffective for several weeks because the surfaces become repellent. Health authorities also issued warnings in 2026 about the circulation of products banned in France, with cases of serious poisoning. In premises open to the public that handle food, using a biocide not authorised for food environments is an offence in its own right.

2. Confusing an invoice with traceability. An invoice proves you paid. An intervention report proves you diagnosed, treated and followed up. Always require a written report from the contractor stating: species identified, areas concerned, products and active substances used, dosages, structural recommendations, date of follow-up visit.

3. Failing to date the start of the problem. An operator who answers "I don't know, it's been a while" puts themselves in a position of negligence. An operator who produces a log showing 0 catches in June, 3 in August, 11 in September, with an intervention requested on 4 September, demonstrates active control. That's why a set of numbered monitoring glue traps, checked every week and recorded in a logbook, is the best cost/benefit investment a professional kitchen can make.

4. Treating the restaurant in isolation within a building. German cockroaches travel through vertical service ducts. If the flat upstairs is infested, any isolated treatment is a stay of execution. The matter must be raised with the managing agent in writing, with a request for coordinated treatment of the whole riser.

5. Neglecting the goods reception area. A pallet of cardboard boxes left on the floor in a corridor for two days is enough. The professional reflex: unbox in a dedicated area, discard outer packaging immediately, and never let a cardboard box into the production area.

The 15-day compliance protocol

Here is the sequence we apply with operators who want to take back control, whether before an inspection or after a formal notice.

Days 1 to 3 — a diagnosis with numbers

Install a grid of monitoring traps: one device every 3 to 4 linear metres in high-risk areas, numbered, positioned in corners rather than flat in the middle of a room. Check at 72 hours. You end up with a map of the infestation hotspots instead of a general impression. This is also the stage at which a narrow-beam torch becomes the most useful tool of the internal inspection: it reveals droppings in hinges and crevices that ceiling lighting hides completely.

Days 3 to 5 — preparing the surfaces

Complete degreasing of the targeted areas. Bait gels only work on clean, untreated surfaces: a professional food-safe degreaser, rinsed off, is the precondition for the treatment that follows. Remove all cardboard from stock, transfer flours, semolina, pasta and cereals into stackable airtight food containers — which simultaneously removes the food source for cockroaches and for pantry moths.

Days 5 to 7 — targeted treatment

Application of bait gel with an active substance authorised for food environments, in dots of 0.1 to 0.3 g, numerous and placed close to the hotspots, never in a continuous line. Supplemented by dust or gel in inaccessible technical voids. Using growth regulators makes it possible to act on juvenile stages and egg cases, which escape conventional treatments. This phase is the job of a certified applicator — the Certibiocide certification is, incidentally, something checked during inspections.

Days 7 to 12 — proofing

This is the phase everyone skips and the one that determines the result six months later:

• sealing pipe penetrations with mortar or foam, then finishing smooth;
• replacing split cold room seals;
• fitting brush door bottoms on service exits;
• refilling and checking floor traps;
• verifying that every piece of mobile equipment can be pulled out for cleaning.

A kit of seals and sanitary sealant that stands up to frequent cleaning is enough for 80% of the points to be dealt with in a standard kitchen.

Days 12 to 15 — documentation

Rebuild the pest file: annotated site plan, monitoring logbook, intervention reports, product data sheets, up-to-date cleaning and disinfection schedule, staff training certificate. A dedicated physical folder, kept in the stockroom: it's the first document an inspector asks for, and producing it within thirty seconds changes the tone of the entire visit.

Training staff: the most profitable link

A perfect plan on paper fails if the commis doesn't know what to do when they see an insect. Three simple instructions, displayed on the wall:

1. Don't crush it, don't spray it. Report it.
2. Record it in the logbook: date, time, precise location, stage (juvenile or adult). A juvenile means breeding on site, so an internal hotspot — crucial information.
3. Photograph it if possible. A dated photo counts as evidence of vigilance.

Half an hour of awareness training at the start of the season, recorded on an attendance sheet, ticks a regulatory requirement and genuinely improves early detection. For establishments building or revising their food safety management plan, a practical HACCP guide for catering remains a useful resource for structuring the expected documents, alongside the good hygiene practice guides validated by the DGAL.

Key takeaways

• A health inspection doesn't judge the presence of insects but the ability to detect it, date it and treat it.
• The pest control plan must be written, mapped and checked regularly: a plan that isn't kept up to date is as good as no plan.
• Structural proofing and removing cardboard from the production area deliver more lasting results than any amount of repeated chemical treatment.
• Off-the-shelf aerosol insecticides make the situation worse in a professional setting and expose you to an offence.
• In a shared building, control must be coordinated with the managing agent, otherwise it amounts to nothing more than a reprieve.

An inspection is prepared in advance, not on the day. If your last intervention report is more than three months old, or if you don't know how many catches your traps have recorded this month, compliance isn't established — it's simply unassessed.
