Mouse Shield is non-toxic and contains natural fibres and oils. The strength of the product lies not in killing rodents but in blocking their access. Mouse Shield is non-toxic, so it is ideal for use in areas where food products are stored or processed. The unique soft core ensures that vermin are repelled as soon as they gnaw through the outer layer of material. Mouse Shield is packed in a 300mL tube and easily applied using a standard caulking gun.
