Rats and Mice are well known for spreading diseases such as plague, weils disease and cryptospridiosis but this article focuses on their gnawing behaviour, why they do it and what risks it presents to public health.
Rodents are characterised by their teeth. They have a pair of incisor teeth in the upper and lower jaws, separated from the molars by a large gap (diastema).
The incisors do not stop growing. This means that the animals are forced to gnaw steadily in order to wear them down.
This picture shows a skull from a rodent specimen who’s incisors hadn’t worn correctly and had become overgrown.
The incisors are curved inwards and have an extremely hard anterior coating,The enamel of rat incisors is hard, harder than iron, platinum and copper.
The softer inside layer is worn down much more rapidly than the hard, outer layer.This means that the teeth are continually kept sharp, enabling them to damage even materials such as masonry and electric cables.
Rats are believed to have caused a massive blaze that destroyed three coaches and three minibuses at a coach company headquarters in Southampton in December of 2012.
The rat has small flaps of cheek tissue on either side of the inside of the mouth that close behind the incisors, protruding into the gap between the incisors and the molars (the diastema) These flaps are believed to form a plug that keeps unwanted debris from entering the mouth,a rat does not have to swallow or even taste what it chews,allowing them to gnaw away with impunity.
Here, we have the skull of Rattus norwegicus, The Brown rat, the incisors and diastema are clearly visible.
Next, A Grey Squirrel, Sciurus Carolinensis.
Here we see the very clear teethmarks of a brown rat on a piece of electrical cable.
this is an old bait tray, that would have held rodenticides once, it would appear that the local rodent population not only consumed the bait but found themselves partial to the plastic tray themselves.
If you suspect that you have rodents in your property, The safest and most efficient way to deal with them is to contact a professional pest control company, such as Cavalry Pest Solutions.

Ethical Pest Control….Whatever Next?
Wigan‘s Entrepreneurial Pest Controller, Elliot Lowe is at it again with what he believes is a first for the U.K’s Pest Management Industry.
Elliot is in the process of launching Cavalry Pest Solutions as a Community
Interest Company, a non-profit social enterprise.
Elliot explained “It’s really quite simple, A CiC is run just like an ordinary LTD
Company but has an asset lock and a profit cap set by the government, profits
made by the company above this are re-invested into the community.
Cavalry Pest Solutions CiC will provide professional & efficient Pest Control to
domestic, commercial & Rural customers and the surplus profits will be directed to providing free educational talks and workshops to community
groups and to providing a form of subsidised Pest Control that supports Local
A booklet published by the Chartered Institute of Environmental Health, ‘The
Perfect Storm’ and a recent Episode of Panorama have highlighted the potential consequences of budget Cuts on Council Pest Control Departments.
The Chief Executive of The Chartered Institute for Environmental Health, Mr Graham Jukes believes that the proposal “is very much in line with current government thinking and will add in some way to addressing the problem of the poor and disadvantaged in dealing with pest control problems”.
The Pest Control Industry is undergoing a huge period of change due to
European legislation as well as dealing with the effect of the current austerity
measures and Elliot feels that his new approach has the potential to make a
significant contribution “Both the British Pest Control Association and the
CIEH have highlighted the fact that the public image of the Pest Control
Industry needs changing and I am firmly committed to using Cavalry Pest
Solutions CIC to contribute to raising the profile of our Industry whilst at the
same time providing support to Local Authorities that hopefully may ease
some of the financial pressure they are under. I’m passionate about Pest
Control, It’s my profession and I’m proud of it, and I feel privileged to be part of something that can make a difference. Customers can feel that too, knowing that whenever they choose Cavalry Pest Solutions to provide Pest Control
Inspections, Treatments and Proofing, a percentage will be invested into
improving the quality of living of those most in need”
