Black plastic sheets in the garden: why they attract vipers

Between the patio, vegetable patch and garden shed, there is often something that barely attracts anyone’s attention – yet for adders and other vipers it becomes an ideal hiding place. Understanding why this material is so appealing can make a property considerably safer with just a few simple measures, without resorting to panic pruning.

Why vipers suddenly appear in the garden

In Central Europe, vipers are by no means found only in remote mountain areas. They now encounter excellent conditions in rural settlements, on the edge of villages and in sparsely built-up residential areas. They hunt mice, young birds and lizards, while using structures created by people as shelter.

Snakes are cold-blooded animals. They rely on external warmth to become active, hunt and digest food. For many species, temperatures of roughly 25 to 30 degrees are ideal. This is precisely where a common garden mistake comes into play, consistently providing these temperatures day after day.

Warm, undisturbed areas in the garden

“Where heat builds up and the area remains quiet, a ‘temporary snake room’ forms almost by itself – right between the beds and the patio.”

The overlooked risk: black plastic sheets in the garden

It is usually not piles of stones or natural walls that prove most attractive, but an apparently practical aid: dark, often black plastic sheets or synthetic weed-control fabrics laid directly on the ground.
