Geraniol Surface Repellents vs Repeltec: Why the EU Phase-Out Is Actually an Upgrade

⚠ Use biocides safely. Always read the label and product information before use.

With geraniol-based biocidal products being phased out of the EU market — the current approval extension expires 30 April 2026 — distributors and retailers are asking the obvious question: what replaces them?

This post answers that question specifically for surface repellent applications: products sprayed onto surfaces, textiles, walls, floors, and furnishings to create a treated zone that deters insects. This is an important distinction. Most repellent comparisons focus on skin-applied products. Surface repellents operate differently, last differently, and are evaluated differently — and it is in surface applications where the gap between geraniol-based products and Repeltec is most stark.

What geraniol-based surface repellents actually deliver

Geraniol has been used as an active ingredient in surface repellent sprays, diffusers, and impregnated textiles. Its appeal was straightforward: botanical origin, perceived safety, and a recognizable scent associated with citronella and rose oil.

The performance reality for surface applications was always more modest. When geraniol is applied to a surface, it begins volatilizing — evaporating into the air — almost immediately. This volatilization is what creates the spatial repellency effect, but it also means the active depletes rapidly. Independent field studies consistently show geraniol surface treatments delivering repellency for under two hours, often significantly less under warm indoor conditions where airflow accelerates evaporation.

For a distributor selling a surface repellent to a hotel, a hospital, or a facility manager, this means their customer is reapplying the product daily — or multiple times per day — to maintain any effect. The cost-per-protected-day is high. The user experience is poor. The environmental load from repeated applications accumulates.

And as of April 30 2026, this product can no longer be legally placed on the EU market under BPR at all.

What Repeltec delivers on the same surfaces

Repeltec was designed specifically as a surface repellent. It is not a skin spray adapted for surfaces — it is a surface treatment built from the ground up for long-duration performance on treated materials.

The core of its performance is Affix Labs' patented water-based controlled-release platform. When Repeltec is sprayed onto a surface, it does not simply deposit icaridin on the material and begin evaporating. Instead, the formulation forms a transparent, odourless coating in which the active ingredient is encapsulated within a biodegradable matrix. This matrix controls the rate of release — delivering Icaridin consistently and gradually over time rather than all at once.

The result: a single application of Repeltec provides surface repellency for up to 12 weeks, independently validated by third party test labs around the world.

Twelve weeks from a single spray. On the same surface where a geraniol product would need to be reapplied more than 250 times to cover the same period.

Head to head: geraniol surface repellent vs Repeltec

Why the controlled-release platform changes everything for surface applications

The critical insight is this: the active ingredient is only part of the story. How that active ingredient is delivered to and retained on a surface determines whether a product is useful for surface protection or not.

Icaridin has significantly lower vapour pressure than geraniol, which means it persists on surfaces for longer even in a standard formulation. But Affix Labs' controlled-release platform extends this further still — by encapsulating the active in a biodegradable matrix that regulates its release rate, the platform converts what would be a multi-hour surface treatment into a multi-week one.

The platform is the differentiator. The same icaridin that lasts a few hours in a conventional spray lasts up to 12 weeks in Repeltec because of how it is delivered, not just what it is.

This is why Repeltec is not simply a "geraniol replacement." It is a fundamentally different category of product — one that happens to be the right answer at the moment the old category is being regulated out of existence.

What this means for distributors replacing geraniol SKUs

If you currently carry geraniol-based surface repellent products in your portfolio, the April 30 deadline is not an abstract regulatory event. No new products can be placed on the market after this deadline and it wont be long before Geraniol based products disappear from the shelves as a whole.

The replacement is not like-for-like. Repeltec does not perform like geraniol — it performs dramatically better. This is actually a commercial opportunity: you are not replacing a product with an equivalent, you are upgrading your range with a product that gives your customers a fundamentally better experience and removes the need for the repeated purchases that made geraniol products feel cheap and disposable.

The Powered by Affix Labs white-label programme

Affix Labs makes Repeltec available for white-label supply under the Powered by Affix Labs programme. Distributors and brand owners can sell Repeltec under their own brand name with custom labelling and packaging, while the underlying formulation, patent, and regulatory standing remain with Affix Labs.

With the new season, lead times matter. The typical onboarding timeline from first enquiry to first order delivery is 6–12 weeks. Starting that conversation now gives you product on shelf before the geraniol withdrawal forces your hand.

Summary

Geraniol-based surface repellents are leaving the EU market. The approval extension expires 30 April 2026 and no company stepped forward to defend the substance through the full BPR process. The reasons are clear from the performance data: short duration, sensitisation concerns, aquatic toxicity issues, and a fundamental incompatibility between the molecule's volatile nature and the demands of long-duration surface protection.

Repeltec replaces geraniol-based surface repellents not as a like-for-like substitute but as a significant upgrade — delivering up to 12 weeks of surface protection per application through a patented controlled-release platform, with a regulatory pathway in place and white-label supply available now.

The phase-out is not a problem. For distributors who move early, it is an opportunity.

Affix Labs produces Repeltec, a surface insect repellent with white-label supply is available under the Powered by Affix Labs programme.
