Proofing Against Rodents

Why Proof against Rodents 

The image to the right is of water pipes, waste pipe and electrical cables passing through an opening in a wall inside a house.  This work was as part of extension being built a few years ago and has been left like this.  The property has had a number of infestations by rats which in turn have been dealt with by a number of pest control companies.  

In each case the owners were advised that they would need to have the openings, holes and gaps repaired (filled, sealed) if they didn't want the problem to return.  There are many holes in this property making it easy for rats to invade but the owners chose not to take the pest controllers' advice.

The owners went away for a few days recently and when they returned, rats had gnawed through a plastic water pipe causing a major flood approximating in about £10,000 worth of damage.  Most of the cost was borne by the owner.  The proofing work was a few hundred pounds.

Still it could have been much worse if the rats had chewed through electrical cables. The owners are now getting the proofing work done as soon as the current infestation is dealt with.

What is proofing against Rodents

Proofing against rodents is simply put, denying them access to your property by filling, covering, repairing or sealing any holes or gaps which allows them to enter.  Rat and mice can squeeze through small gaps which would seem impossible looking at the size of them but if their head can fit through then they can.

If you have a problem with rats or mice or squirrels, they must have got in some how.  Part of the pest controller's role is to find out how they got in and advise on the best course of action following treatment. 

All recommendations should be taken seriously as rodents can do extensive damage as in the case mentioned earlier.

These images are of  examples of damage caused to property giving rodents access.

This is a broken air vent that needed to be replaced.  A temporary measure would be to cover it with a wire mesh.      






This image is of a shutter door which had a gap of about 30 millimetres when fully closed.  Fully grown rats were using this as an access point into this premises.  The proofing required here was a bristle strip or weather seal.





This image shows the damage caused by rats gnawing on the insulation around hot water pipes.  Rats can gnaw through copper pipes so it was only a matter of time before this would be an expensive repair job.




In this image mice are using the gap that the pipes pass through as a conduit into the underfloor cavity in this building.  The remedy here is to fill this gap and create a boundary that stops mice from passing through. 



Proofing against rodents should always be carried out after a treatment against infestation and is an effective way of deterring them from re-infesting.
