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.

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. 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?

When rats or mice are present in a building, attention must be given to interior as well as exterior rodent-proofing to remove all sources of shelter. A combination of actions is required in such instances, as no single effort is likely to yield the desired result. 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. 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. 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). 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 Information They are designed to be effective against the consequences to your home of drain flooding after heavy rainfall or burst water mains.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. 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) Figure 22. Guards can be used to prevent rats from climbing augers, pipes, or wires leading to buildings. Footings or foundations for grain bins should extend into the ground to prevent rat burrowing. The valves do not require any maintenance as they are made using 316L grade stainless steel, and once fitted you can rest assured it will do its job for up to 20 or more years. The first and most important advantage of using it is that once it is fitted inside your drain, you can be sure that rats will never be able to enter your home .

Rats can access buildings via the drains and drainage valves or rat flaps can be employed to combat this issue Close openings around augers, pipes, and electric cables where they enter structures with Portland cement mortar, Concrete Patch ®, masonry, or metal collars (Fig. 11).As the valves are one way, they do not stop anything from exiting the pipes in the usual way. After your sewage has freely left the pipe, the valve closes up again automatically.
