A method of preventing the advance of insects of the kind which move on the ground, on parts of biological plants, buildings or the like, wherein a mechanical barrier is placed in the path of the insects. The barrier has the form of a material composed of a large number of thin fibres. According to the invention, there is used flexible, thread-like fibres which are loosely placed together or loosely joined together to form a manageable material composition, such that when coming into contact with the material, an insect can experience the fibres as being the threads of a cobweb and be repelled thereby. The invention also relates to a device for use in carrying out the method. |
