A pesticidal device comprises a support material which is associated with a pesticidal substance and having means for attachment of the support material directly onto the surface of a locus. The attachment means comprises at least one formation adapted to retain the support material on the surface of the locus over a period of time by directly gripping and/or entangling with the surface of the locus. The support material may be separate from the attachment means or integral with it. Attachment means include barbed plastics materials such as hook piled materials, clips and plastics strips with cuts, notches and/or protrusions therein. |
