The invention relates to a barrier for inhibiting the migration of crawling animals such as insects. The barrier comprises a body that is configured to encircle a leg/wheel of a furniture item and thereby intercept any crawling insects. The body has an annular shape defined by an outer boundary and an inner aperture, in which the leg/wheel of the furniture item can be located. The barrier includes inimical means to inhibit the migration of any crawling insects across the body. The barrier further comprises a slit extending radially from the boundary to the aperture so that the body can be reversibly opened and closed. The slit advantageously allows the body to be opened and closed around the leg/wheel of the furniture item during installation. Likewise, the slit allows the device to be reopened and extracted from around the leg/wheel of the furniture item during removal. As a result, the device can be installed, removed, replaced or retrofitted easily and quickly without having to lift, move and/or disassemble the furniture item. The invention further relates to a method of inhibiting the migration of crawling insects by mounting the said barrier around a leg/wheel of a furniture item, relates to a kit comprising a plurality of barriers and relates to a furniture item protected from crawling insects where a said barrier is mounted for use around a leg/wheel of the furniture item.
