Mcalpine ARB-1 Anti Cross-Flow and Rodent Barrier Valve, Black

Product Information

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. Audit Compliance– proofing expansion joint gaps supports your audit compliance by proactively minimising the risks associated with internal mouse and rat activity. This in turn reduces the need to use rodenticide within your facility to control infestationsas you arerestricting rodent access.

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) 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:

Mice can fit through surprisingly small spaces. As such, we recommend mesh that has a hole size no greater than 6 mm x 6 mm. As a general rule of thumb, if you can get a biro through a hole a mouse can fit through too. If you’re not looking to stop rats and mice are the only concern then our galvanised mouse mesh will likely do the job. This can be bought in our online shop here. Mouse mesh should always have a maximum hole size of 6 mm x 6mm. Close openings around augers, pipes, and electric cables where they enter structures with Portland cement mortar, Concrete Patch ®, masonry, or metal collars (Fig. 11). 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.

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. It is a highly affordable way to stop rats from entering your home through the toilet. The price of the unit itself plus our charge for fitting is extremely cost-efficient. 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. 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.We sell standard insect mesh in various widths. The narrower width rolls (50 mm to 400 mm) we describe as soffit vent mesh or simply soffit mesh. Regardless of the name, this mesh is identical to standard insect mesh. Soffit vent mesh is available to buy in our online shop soffit mesh category. Midge Mesh Entry Barrier to Rodents - Kevlar and knitted steel mesh core combination (unique to Rentokil UK) is flexible yet strong enough to prevent gnawing rodents creating entrance gaps under pedestrian and roller shutter doors. 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. There are many points of potential entry into a building for a rodent. One of the reasons businesses develop pest problems is because they don’t fully rodent-proof their premises’. Proofing is always the first line of defense against rodent infestations. The Flexi Armour rodent proofing range of door seals provides effective proofing measures, to help prevent the entry of rats and mice and reduce the risk of a rodent infestation developing on your premises. Rats typically burrow and nest under feed bunks that are placed directly on the ground or near ground level. Properly designed concrete bunks that sit tightly on a concrete base eliminate rodent habitat. Though cattle traffic may discourage burrowing under the concrete slab, a foundation may be needed to prevent burrowing around the sides of the slab that do not receive heavy cattle use. Concrete slabs on which feed bins are placed should have foundations extending 36 inches (91 cm) into the soil at the outer edge to prevent rats from burrowing under the slab. Installing heavy gravel and maintaining a clean, weed-free zone around the perimeter of the slab will also discourage rat burrowing and permit easier detection of rat activity.
