Certibiocide: Disinfectants, Pests or Other Products — Which Category Applies to You?

It is the costliest mistake in the scheme, and it happens before the first course booking: there is no generic “Certibiocide”. Since the reform applicable from 1 January 2024, France’s individual biocidal-product certificate comes in three categories, and holding one authorises nothing under the others.

Many professionals find this out late — sometimes after paying for a session that did not cover their actual work. Here is the method for identifying the right category first time.

The three categories in one table

Category	What it covers	Product types
Disinfectants	Professional hygiene and disinfection	PT2, PT3, PT4
Pests	Pest control: rodents, insects	notably PT14, PT18
Other products	Material protection, antifouling	notably PT8, PT21

This split is recent in the life of the scheme. Before the revision of the order of 9 October 2013, attention focused mainly on pest control: that is why a certificate obtained several years ago no longer necessarily matches its holder’s current activity.

The method: start from the product, not the trade

The natural instinct is to reason by profession — “I do rodent control, so it’s the pests category”. It is misleading, because most firms have widened their offer.

The reliable method starts from the products. Biocides are classified at European level by product type, abbreviated PT, and it is that classification which governs the certificate category. The useful markers:

• PT2 — disinfectants for surfaces, materials and equipment, swimming-pool and water-treatment products;
• PT3 — veterinary hygiene;
• PT4 — surfaces in contact with food and animal feed;
• PT8 — wood preservation products;
• PT14 — rodenticides, products for controlling rodents;
• PT18 — insecticides, acaricides and products against other arthropods;
• PT21 — antifouling products.

The information appears on each product’s label and safety data sheet. Two clarifications matter. First, only products restricted to professional use trigger the requirement: a product intended for the general public stays outside the scope. Second, one site may hold products from different categories without realising it — a rodent bait in a plant room, a surface disinfectant in the cleaning cupboard.

Three situations where one category is not enough

The pest-control firm that added disinfection. The shift has been substantial in recent years. Technicians certified for “pests” are not covered for professional disinfection work: the “disinfectants” category, mandatory since 1 January 2026, is added, not inferred.

The cleaning company that also handles pests. The mirror image. An operative trained on disinfectants is not authorised to lay rodent baits.

The construction firm treating timber. Roof-timber treatment and structural wood protection fall under PT8, hence the “other products” category. Many tradespeople overlook this field, because the product is seen as a site consumable rather than as a biocide.

Every time, the reasoning is the same: categories add up, they do not substitute for one another.

User or distributor: a second dimension

Choosing the category does not exhaust the question. The scheme also distinguishes two activities: professional use on one side — operatives and technicians, but also the people who decide on purchases and how work is organised — and purchasing and distribution on the other.

A cleaning-products distributor listing a professional disinfectant falls within scope, even if they never use it. This is the most frequently forgotten strand: we have covered it in our article on who is affected by the requirement.

Why the split by category makes technical sense

One could read these three categories as administrative complication. Yet the technical issues they cover differ greatly, and the scientific literature shows it clearly.

On rodent control, the dominant question is resistance and unintended effects. A review published in 2024 in Animal Conservation by Keating and colleagues produced a global synthesis of wild carnivore exposure to anticoagulant rodenticides and documents widespread contamination of non-target species (see the study). A trained applicator must know how to secure bait stations and reason about quantities: that is know-how specific to this category.

On insect control, the central subject is insecticide resistance. A synthesis published in 2025 in Entomological Research by Lee on bed-bug insecticide resistance and management options recalls that field populations are largely resistant to pyrethroids and that combination strategies call for particular vigilance (see the study).

On disinfectants, finally, the issue is the selection of less susceptible micro-organisms. A systematic review published in 2024 in the Journal of Hospital Infection by Fernandes, Rodrigues and Cobrado examined the effects of prolonged disinfectant exposure on resistance profiles (see the study).

Three fields, three distinct technical bodies of knowledge: the certificate’s split follows that reality rather than an administrative logic.

Checking your own certificate

If you already hold a Certibiocide, three checks are needed, in this order:

1. Which categories appear on it — not “do I have a Certibiocide”;
2. Which activity is covered: professional use, purchasing and distribution, or both;
3. Which expiry date, the certificate being valid for five years. Renewal is covered in our dedicated article.

Those three pieces of information, set against your product inventory, are enough to build your compliance plan.

Take action

Open the cupboard, note the product types on the labels, and match them against the three categories. That is an hour’s work which avoids a pointless training session or, worse, work carried out without the required certificate. The full Certibiocide profile covers the categories, the steps and the applicable texts in detail, and the certifications hub will let you check whether other schemes apply to your activity.
