Few people suspect it, but ordinary corrugated cardboard can become an unexpected helper in the fight against pests in the garden. For example, in Poland gardeners are advised to wrap the trunks of fruit trees with it to create a kind of trap for insects.
Polish publication Dziennik experts described this simple and eco-friendly method.
Why do pests hide in cardboard?
Many insects seek cozy, protected places for development, pupation, or overwintering. Corrugated cardboard with its numerous folds can mimic natural crevices in tree bark. Pests hide inside such wrapping, after which the cardboard can be removed and disposed of along with the insects.
According to experts, this method can help reduce the numbers of certain pests without the constant use of chemical plant protection products.
When should cardboard bands be installed?
It is important to choose the right time, since timing depends on the life cycle of the specific pest. To fight, in particular, the plum fruit moth, the first cardboard wraps are recommended to be installed around mid-May.

A second wave can be done in late summer. Spring bands are removed at the end of the season, while those installed at the end of August can be left until winter or early spring. After use, the cardboard must be disposed of properly so that any pests remaining inside do not continue their development.

How to properly wrap a tree with cardboard?
For the trap you will need ordinary corrugated cardboard about 10 – 20 centimeters wide. It is wrapped around the trunk, usually at a height of about 50 – 60 centimeters from the ground, and secured with twine or string.
At the same time, the wrapping should not press the bark too tightly. Cardboard bands also need to be checked regularly and replaced if necessary.
Will cardboard save the whole orchard?
A cardboard band alone is not always able to fully protect trees, especially if pests are already very numerous in the garden. Therefore mechanical traps are best combined with other protection methods:
regular inspection of trees,
removal of damaged fruit and other preventive measures.
Similar cardboard wrappings can be used not only on plums but on other fruit trees as well — including apple, pear, sour cherry, sweet cherry, peach, and apricot trees. The main thing is to consider which specific pests are a problem in a given garden.
