Frequently Asked Questions

When can I use 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 nuisance, especially in strong winds.

Which companies can use this product with me?
For your Catefix processor we refer you to our page: ''references''.

Is the product ready to use or does it still need to be diluted or thinned?
Catefix is immediately ready for use and does not need to be diluted. For more information, see the product data sheet on our website ''About Catefix''.

What are the necessary precautions?
During the treatment it is recommended to wear safety glasses in addition to the usual protective equipment for contact with fire hairs. For the treatment of a nest, please refer to the product data sheet on our website "About Catefix". 

What should I use to apply Catefix?
Catefix can be applied with a low pressure sprayer. You can obtain it from any local gardening materials specialist.

When can I start using Catefix?
Catefix is used as soon as the nest is visible. So you don't have to wait until the caterpillar has fire hairs. Catefix can be used both curatively and preventively.

Can I use it myself or do I have to have it done?
We advise you to apply Catefix within the guidelines indicated in the product's technical data sheet. See the product data sheet on our website ''About Catefix''.

Once the nest has been treated, does it have to be removed or can it remain in place?
The starting position of the Catefix is that the nest remains in place after treatment.

I now treat the nests with suction equipment. How can I combine the Catefix with my current treatment methods?
Catefix is ideal to be used in combination with your current extraction equipment. We advise you to remove the nests that are visible within the first 2 metres with your extraction equipment and use the Catefix from that point on. The treatment of the Catefix takes about 1 to 2 minutes per nest and is therefore more effective, allowing more nests to be treated in less time.

How long does it take to treat a nest?
Approximately 1 to 2 minutes.

Is a single treatment sufficient or do I need several treatments?
1 treatment (if done properly) is sufficient.

Do you have a step-by-step treatment plan?
Yes, this can be found in the product information sheet on our website ''About Catefix''.

How long will the nest stay fixed after treatment?
The nest remains fixed for the whole season.

Is the product also suitable for the pine processionary caterpillar?
Catefix can be used in the same way for oak processionary caterpillars and pine processionary caterpillars.

Can I use Catefix after treating a nest with another product?
No, we do not recommend it.

Is a follow-up check necessary?
No, when the nest has been treated correctly, this is not applicable.

How long can Catefix be stored?
Catefix can be stored for up to 12 months. For more information, see the product data sheet on our website ''About Catefix''.

How long after the application does it take for Catefix to take effect?
Catefix is active immediately after treatment. The nest, including the fire hairs, is fixed immediately.

What happens if it starts raining?
During a thunderstorm, the fixative becomes sticky again. The nest therefore contracts even more after drying. After a while, the nest will be destroyed with the fixative.

What happens if the nest falls out of the tree?
If a treated nest falls out of the tree, it will be held together by Catefix. This is in contrast to an untreated nest.
