Oak processionary caterpillar removal in Barneveld
Never take a nest out of your oak yourself. The stinging hairs are the reason I go in wearing a protective suit.

Recognising a nest, and when
The oak processionary caterpillar lives in oaks. If there is no oak in your garden, it is almost certainly something else.
- A nest looks like a felted, greyish pack against the trunk or in the fork of a thick branch.
- There is often some webbing around it, and the pack sits firmly on the bark.
- The caterpillars walk up the trunk in a long line, one behind the other. That is where the name comes from.
- You usually see them from late spring onwards, and the nests can hang there into the summer.
- An empty nest is a nuisance too, because the hairs stay behind in it.
Not sure whether it is the oak processionary caterpillar? Take a photo from a safe distance and message it to me. Then I will tell you what it is, before you do anything.
Never take a nest out yourself
This is the one piece of advice on this page that I give with real emphasis. Stay away from it and leave it to someone with the kit for it.
- The caterpillar has stinging hairs. They come loose and spread through the air.
- That is why I go in wearing a protective suit. Garden trousers and gloves are not that.
- Spraying with the hose or poking at it makes things worse: that is exactly what releases the hairs.
- Keep children and pets away from the tree and hang the washing somewhere else for the time being.
How I go about it
I climb the tree, so a nest high in the crown or on the far side of the trunk is reachable as well. No cherry picker has to come into your garden.
- A look first
You send a photo or I come by. I look at where the nests are and how many there are.
- Into the tree in a protective suit
Fully closed, with protection for face and breathing. That is not for show.
- Removing the nest at the source
I work from up in the tree, close to the nest, so as little movement as possible gets into it.
- It goes with me
What comes off is not left lying in your garden. I take it with me when I leave.
