Catefix is fully biodegradable, non-toxic and durable.


Catefix has been specially developed to eliminate the nuisance of the oak processionary caterpillar and the pine processionary caterpillar. Our starting point was and still is that the nest does not need to be removed after treatment. This contributes to a fast, durable and effective solution. 

Product characteristics

Catefix is made exclusively from natural, vegetable and renewable raw materials. Catefix is non-toxic, contains no solvents, plasticizers or heavy metals. Catefix - once applied - completely penetrates the nest and forms a hard (not sticky) fixing layer that completely seals the nest. Catefix is PH-neutral, which means that it does not cause any damage to nature.  

Catefix has only a physical effect. The Ctgb states that - in accordance with European legislation - it is not required to judge the safety and effectiveness of this product.

The enforcement of legislation concerning the use of authorised plant protection products and biocides is the responsibility of the Dutch Food and Consumer Product Safety Authority (NVWA) and the Environment and Transport Inspectorate. The control authorities agree with the Ctgb's opinion on the product Catefix 2020.

The operation 

The processionary caterpillar with all its stinging hairs is somehow "fixed", which means that the caterpillars in the nest can no longer search for food. 

During the injection, the fixative seeps into the nest and the caterpillars begin to move. The caterpillars themselves distribute the fixative in the nest and are glued together. After some time, a massive pile of fixatives and caterpillars forms.

The caterpillars die and are completely encapsulated. With Catefix 2020 the nest forms a hard shell after drying.

What happens when it starts raining?

During a rain shower, the fixative becomes sticky again. The nest therefore contracts even more after drying. Over time, the nest will be destroyed along with the fixative.

And what happens when the nest falls from the tree?

If a treated nest falls out of the tree, the Catefix 2020 will preserve everything. This is in contrast to an untreated nest.

When can I use the Catefix?

It does not matter at what stage, from larva to butterfly, the nest is treated. Here the rule applies: the sooner the better. Even just before the butterflies fly away, a nest can still be treated. This is why butterflies cannot fly away and reproduce. The remains of caterpillars and hairs are also fixed. Old, untreated nests from last season can also be treated. This prevents them from causing any nuisance, especially in strong winds.

Cost-effectiveness, simplicity and efficiency 

Our method of working results in considerable savings. On the one hand, Catefix can handle a high number of nests per hour, on the other hand, the supply chain is simple. For example, there is no need to use special big bags and plastic drums to dispose of EPC waste, nor to transport it to the already "limited" treatment sites. The more efficient working method mentioned above reduces the CO2 footprint.

Catefix can easily be installed by a professional landscaper/arborist. Not only do we create more flexibility in planning and (treatment) capacity, but we also achieve shorter waiting times (due to the limited availability of removal equipment) in the control of the processionary caterpillar. Apart from that, in "season" we eliminate direct nuisances from municipalities, companies and private individuals more quickly. Quite simply because landscapers and arboriculturists can respond more quickly and efficiently to demand.


Using a low-pressure spray, spray the outer ring of the nest with an overlap of about 5 cm. Then spray the entire nest. Spray an additional layer on top of the nest so that the Catefix can penetrate deep into the nest. Ready to use!

After using the low-pressure spray, it is a good idea to seal the nozzle with, for example, plastic film to prevent it from drying out.


During the treatment, it is recommended to wear safety glasses in addition to the usual protective equipment for contact with fire hairs.
