Pest controllers RES ..and the historic rodent issues now haunting modern-day London

You may or may not know that the city of London in general has something of an historic ongoing ‘today’  problem with rats and mice, which have thrived as a result of the ever changing human structural advancement in the City over the centuries. So, speculates our latest IMD online recruit the Regional Environmental Services company…..


RES is an established business that serves the whole of the UK capital city and also surrounding Southern Counties regarding all bird waste/fouling and pest control problems. Their team are specialist surveyors and technicians with considerable expertise in pest control and relating to pest presence. The business belongs to the BPCA which provides continual legislative updates on all aspects of pest control and  relating handling requirement.

CRRU code 

It operates in step with relevant industry codes of practice and progress. It is a compliant with and has a full understanding of the CRRU code of best practice of March 2015  and ensures its field personnel  are always qualified to use and administer rodenticides in accordance with precise practices. All RES staff undergo updating training via specialist seminars where qualification certificates are issued, following post course tests. All technicians receive industry periodicals as a method of update on legislation and varying codes of practice.


So, that’s all about RES … now read to get their informed thoughts on  the rats and mice and other pests of London and why they are there.  As mentioned already,  the type and style of structural development in London over the years  has  left in its wake the obsolete foundations of the past, which apparently – suggests  RES –  serves as a ‘thoroughfare’ for rats and mice to go through to the many modern structures – in particular offices and also intensive older-styled apartment development areas.


The combination of this situation and both rats and mice being enticed in by tasty morsels of food being left in the work environment leads to ever greater numbers of rodent sightings. The numbers of rats and mice accessing any building will vary depending upon circumstance such as rise in water table, seasonal change or construction works, nearby.  All this occurs despite the pest controllers best efforts to entice mice to eat bait or go into traps. Thus any pest control service and system within a building has to be a programme requiring client co-operation to achieve the prime objective of reducing numbers of rats or mice in any particular building.

not prevention 

Focusing on mice, pest control is very much control and could not be considered prevention, especially in the urban environment where there are too many unpreventable factors to offer the latter. Pest control in regard of the customer contractor relationship, has always been a two way street requiring the co-operation of the customer so that the pest controllers expertise is put to good effect.

hand wipes

Due to the modern way of working it is common practice to eat at work stations, with there being very few exceptions to this trend. This can be managed to avoid the availability of food, and food packaging to mice. Crumbs as well as finger smears on desks or inside desk drawers, also packets of food, opened bottles of fruit juice, are not invisible to the sensitive nose of the mouse.  Thus food should never be left in desk drawers. Hand wipes should always be used, following eating and crumbs hand swept into a bag or food container. Bottles of soft drinks should be removed from site at the end of each day, along with all food and food waste.


It is bad enough to have the trauma of seeing a mouse in the office and the revulsion of seeing mouse droppings on a desk, however just as bad if not worse is the unseen urine trails across desks, which are produced by the naturally incontinent mice.There is an infection risk such as salmonella when mice are present, and this is greatly heightened when food is being eaten on a desk, where there have been mice. This is where food or hands come into contact, directly with bacteria infected urine or droppings.


Mice are less likely to forage and cross desks if no food is present. Our intention is to deal with mice in the building service risers and sub floor areas, where there would be no contact with office staff, thus reducing this risk of infection to virtually zero. We do need help in achieving this by staff having an awareness that there must be a code of hygiene observed, not just for the sake of seeing less mice, but more importantly for the health and safety obligation to themselves, as well as their colleagues.


A planned programme should be put into place in order to reduce the issues encountered with mice in a building and should be implemented with the full knowledge and understanding of the building staff that we do require co – operation in regard of food handling. 

effectively trap

This will enable us to effectively trap and bait by focusing the mice on eating what we put down, without the distraction of more tasty morsels nearby.The only long-term method to control rodent populations is to make the area unattractive or inaccessible to them. Eliminate their food sources by keeping desk surfaces, floors, and cabinets clean……so if you work or live in London you perhaps now know what to do
