Roshield Rodent Proofing Paste
Mastic paste to prevent rat & mouse ingress
- Prevents rodent & insect access
- 100% non-toxic
- Easy to apply
- 2 X 300ml cartridge
Rodent proofing paste is a gap filler that is fast to apply and is also known as a pest-repellent mastic that once in place blocks access for vermin. The unique softcore ensures that vermin are repelled as soon as they gnaw through the outer layer of material

Pests such as rodents and insects occur everywhere. In particular, mice and rats are true masters at gaining access to areas where potential meals are stored. Rodents have a natural tendency to sharpen their front teeth constantly on items such as woodwork, plumbing and electrical wiring.
Rodent proofing paste stops this gnawing behaviour. When the mouse, rat or wasp, for example, reaches the softcore as it gnaws, it is deterred from continuing.
The gap filler is easy to use in existing or new buildings. Although you would not expect them in a new building, unwanted openings are often found; think of ducts for cables, walls (cavity walls), connections for plumbing, or suspended ceilings.
The gap filler is suitable for sealing holes, cracks and seams, joints and expansion joints, settlement cracks and sewer connections. Openings can vary between 5 mm and 10 cm in diameter. Because the gap filler conforms directly to the opening, the opening’s shape and finish are not relevant, provided the surface is dry and clean. The gap filler adheres well to concrete, stucco, masonry, drywall, plastics (such as trespass), metal and wood.
It is straightforward to use mastic. A 300ml paste cartridge is inserted in a caulking gun. The opening is then sealed tight with the material in the gun. Take a look at the video above, which shows in detail how to use the product. Note: the layer of mastic should always be thicker than 10 mm to create a softcore.
Rodent proofing paste is fast to apply for protection against rodents and insects. The 300ml cartridge fits standard caulking guns. The mastic can be applied immediately after the nozzle has been cut off. A hard outer layer gradually forms on the mastic, but the barrier is active immediately. If it nibbles at a sealed opening, the mouse or rat will be deterred almost immediately by the mastic composition on the surface or underlying layer.
Rodent proofing paste is 100% non-toxic and contains natural fibres and oils. The strength of the product lies not in killing the vermin but in blocking their access. Because the gap filler is non-toxic, it is ideal for use in the food industry or areas where food products are stored or processed. Due in part to IPM (Integrated Pest Management), there is a constant search for preventive measures that can be taken to keep mice and rats out of buildings. Working within the IPM and HACCP systems, our proofing paste is an excellent solution for protection against vermin.
After forming the hard (oxygen-excluding) outer sealing layer, the mastic is completely water-resistant and has a life expectancy of 8 to 10 years. Even dirt will scarcely if at all, adhere to the surface. This makes the mastic ideal for inside or outside use. Rodent proofing paste can be used in environments with temperatures between -50c and + 90c
Rodent proofing paste forms an impenetrable barrier against vermin and retains its properties over an extended period. Because it is non-toxic and contains natural fibres and oils, it is both extremely durable and environmentally-friendly. Using this gap filler, you will not need to make any alterations to the building, thus saving on other materials. The use of this repellent mastic reduces the need to use toxic substances that are dangerous to the environment and animals.
The best-known method for coping with vermin is to use pesticides such as poisons. Because this often does not solve the problem and is certainly not animal-friendly, an Integrated Pest Management (IPM) policy for pest control has an important role. The IPM approach does not control the symptoms (kill vermin) but actually solves the problem (removes the cause). Rodent proofing paste repellent mastic ensures that mice, rats and insects cannot reach potential food sources and remain away from the area involved.
Proofing against rodents
Before undertaking any rodent proofing works, we recommend that you survey the property; this will help highlight any possible entrance points, including ones you are unaware of. Pay particular attention to wall junctions, pipework and vents as a general rule; house mice will get through a hole the size of a small pencil and brown rats a 10p coin.
Typical entrance points include:
- Missing or damaged air bricks or vents
- Around pipework on external walls
- Weep holes and gaps in the mortar
- Damaged soffits and fascia
We recommend that you control any established infestation before undertaking proofing works; otherwise, it may hinder any present control treatment as well as potently forcing rodents from finding or creating new access points. However, we do appreciate that in some circumstances, proofing rodents is the only approach if other control measures have had little success, especially when controlling mice within city centres.
Not all access points are visible, and in many circumstances, proofing cannot be undertaken. An example is that you are located in a flat or a mid-terraced building with no control of the surrounding voids and cavities. However, proofing should still be undertaken on a room-by-room basis to prevent internal ingress.
An area that is often overlooked is rats gaining access to the property via the drainage system. A fault within the pipe can be common and often goes undetected, leading to rats gaining access to internal cavities and gardens via tunnels under the ground. If you believe that this might be possible, we recommend placing a drain guard that creates a one-way system, thus preventing rats from accessing.
When possible, it is best to use a combination of materials; an example is our rodent-proofing paste is best used in combination with a mesh to best protect against the highest pressures inflicted by large established infestations.
Once prevention has been undertaken, it is important to clean the areas to remove any bacteria and viruses associated with rodents. Rats, in particular, are a transmitter of several diseases, including Weil’s, which can be harmful to both humans and pets.
Again at Roshield, we have a wide range of options that can complement the treatment process, including a 90% alcohol aerosol for the treatment of a room or our sanitiser and cleaner concentrate spray, which is great for treating large areas that may have been frequented by rodents, such as kitchen cupboards and other voids.
