Store food products in rodent-proof enclosures or on shelving at least 18 inches (46 cm), but preferably 30 inches (76 cm) or more, above the floor. Tubular supports (legs) for shelving should be a minimum of 4 inches (10 cm) in diameter to prevent rats from shinnying up from the floor.

Rentokil Flexi Armour Expansion proofing is a durable combination of flexible yet hard wearing knitted steel mesh with a self-levelling and tough epoxy resin (unique to Rentokil). This sustainable proofing solution is used to eliminate gaps in expansion joints on floors and walls. It seals these narrow spaces preventing rodents from using them as unseen ‘pest highways’ to move through your facility in search of food and harbourages. Flexi Armour Expansion has the flexibility to allow the joints to expand and contract, yet is robust enough to be impenetrable to rodent gnawing. The Rat Barrier was initially developed to help combat flooding problems in the UK but is now being used to prevent rodent ingress into buildings, both commercial and domestic. The valve is now used to prevent the following: Firstly, it is very important to note that rodent mesh is not the same as insect mesh. These meshes are not interchangeable. Rodent mesh is relatively much tougher. Rat mesh and mouse mesh is also more expensive because it contains more metal. Conversely, insect mesh is cheaper, lighter, is woven with fine wires and has much smaller holes. Rats and mice will gnaw through insect mesh with ease. Rat MeshStandard insect mesh (aka fly mesh or flymesh) has a hole size of 1.36 mm x 1.36 mm. This is small enough to stop the vast majority of unwanted insects, including flies, mosquitoes, wasps and bees. Insect mesh is available to buy in our online shop insect mesh category. Soffit Vent Mesh Figure 15. Left: A curtain wall made of concrete will prevent rats from burrowing under foundations to gain entry to buildings. Curtain walls can be installed on existing buildings. A horizontal footing extension often deflects burrowing rodents away from structures. Right: Feed sheds, corn cribs, and other existing wooden structures can be rodent-proofed by installing hardware cloth topped by a band of sheet metal. The hardware cloth can also serve as a curtain wall to prevent rodent burrowing. All vents and duct openings for heating and air conditioning should be screened or raised and/or guarded with an excluder device to prevent rodent entry. Residential cold air return grills can easily be mouse-proofed by placing 1/4-inch (0.6-cm) hardware cloth behind the grill where it is not unsightly. In some applications, power vents can be covered with hinged metal plates (louvered) that open with air flow and close when fans are off. These louvers are only effective if they fit tightly and the sides are recessed to prevent rodents from pushing through them. Caution: Hardware cloth less than 1/2 x 1/2 inch (1.3 x 1.3 cm) significantly reduces air flow. In buildings where ventilation is already marginally adequate or inadequate, such further restrictions may be unacceptable. In some locations, small mesh screens can become clogged with dust or freeze over. In such situations, the use of 1/2 x 1/2-inch (1.3 x 1.3-cm) hardware cloth is a reasonable compromise between ventilation requirements and rodent control. Caution: letting metal siding rest directly against concrete can lead to accelerated rusting and corrosion. The siding should be installed so that openings are no greater than 1/8 inch (0.3 cm) wide. If the siding is installed with the ribs horizontal, the ends must still be sealed or the bottom of the decorative corner trim flashed and closed. Next working day delivery is not available for the Scottish Highlands and some remote areas where an additional charge may apply.

Proper storage and disposal of house-hold garbage and dead animals is a very important part of rat control. Bulk dumpsters are often left with the tops open, or the tops are badly bent, allowing rodent entry. Constant vigilance and calls to the refuse company should correct these situations. Seal bulk trash compactors from rodents. Spilled refuse and juices from crushed contents often create rodent problems under and behind compactors and bulk dumpsters. Clean these areas of-ten and install rodent screening in container drains. Targeted Rodent Proofing– by preventing rodent ingress in these vulnerable areas and removing opportunities for them to nest and find refuge, you minimise the risk of pest activity and limit the potential spread of infestations inside your premises. Properly applied flashing extends to within 1/8 inch (0.3 cm) of the edge of the door at the sides and bottom. Close the gap at the top or sides of roll-up doors with conveyor belt material shaped to fit into the side channel frames and mounted on the top door jamb. Bent bottom rails on doors should be straightened. Concrete dam-age due to inadequate reinforcement or poor placement practices should be repaired or the concrete replaced. A metal or pipe threshold is sometimes preferable or required. Rodent-Proof Construction | Rodent Entry Points | Rodent Exclusion Methods | Rodent-Proof Construction | Rodent-Proof Resources | ICWDM | Wildlife Species InformationThe choice between concrete and wire mesh depends on the expected life of the structure. Though wire mesh costs considerably less than concrete, its usefulness generally lasts only 5 to 10 years. Below, we have outlined the properties of some commonly employed meshes. These include mesh to prevent the passage of rodents (both rats and mice), insects (including specifically midges) and for use in beekeeping applications. Of note, much of the information below has been advised to us by the British Pest Control Association (BPCA). Rodent Mesh (rats and mice) Flexi Armour Expansion Joint Proofing– this resilient yet flexible proofing solution eliminates the gaps in expansion joints on floors and walls in larger premises, preventing rodents chewing through and entering the voids. Rats are great at climbing and swimming, and can hold their breath for long enough that it allows them to travel from one location to another through sewage pipes and drains. Whats The Advantage Of Using A Rat Flap?

Since the 1950’s drainage systems have been much less isolated from the main street sewer and this has allowed rats more access into peoples drainage systems. Damaged or unmaintained storm drains and sewer pipes easily allow vermin access into the main drainage systems. From here they can enter your home by travelling through sewers, up pipes and exiting from the foul air outlet at roof level or swimming through the water contained in your toilet system. The MultiFlap ensures you’re protected by keeping them in the sewers where the authorities can deal with them.

Whats The Advantage Of Using A Rat Flap?

We provide a variety of effective proofing solutions against rodent infestations to help protect every aspect of your business: Please note; this model is made of a high grade plastic, but a determined rat can, and will, chew through plastic. Although this is very rare, it is possible. If this this concerns you, you might like to consider a more expensive stainless steel model (see below in ‘you may also like’ products).
