Rentokil has developed a new, unique tool to help assess the extent of rodent infestations. The Fluorescent Tracking Gel is a specially formulated non-toxic fluorescent gel that highlights rodent tracks on virtually any vertical or horizontal surface.
When a rat or mouse infests a kitchen, restaurant, food store or food processing factory, one of the first tasks is to find out where they are and the routes they take to get to food and shelter. The larger the building, the harder it is to locate the rodents and their hiding places.
The Fluorescent Tracking Gel is making this task much easier and Rentokil technicians are already receiving positive results in field trials on customer premises. Rodents are intelligent, agile and small, they easily into places humans find difficult to access or may not think to look. They can climb cables, wires, pipes, conduits, squeeze through gaps and gnaw holes through many types of material to gain access to buildings and hidden spaces.
The Fluorescent Tracking Gel has been deployed on customer premises worldwide with outstanding results, helping to solve infestation problems that previous conventional control measures could not solve. This new innovation has quickly become a key component in identifying root causes of infestations and adds a smarter tool to the resources of our pest control technicians.
The first step in getting rid of rodents is to survey the infested property to find out where they are and how many there are. Even today, many pest controllers simply lay down bait or traps, without an understanding of the best places to position them on the site. A low-cost service without a proper survey can result in an ongoing problem for businesses when rodents return and cause recurring infestations. The customer often ends up with larger infestations and much higher pest control bills due to the delay in addressing root causes.
There are several factors that make a thorough rodent survey by a trained pest control professional essential:
Rats and mice are highly agile and enter buildings in many ways, so you need to inspect all the vulnerable places that they can access. Rodents can:
Rats and mice have well-developed senses of smell, taste, hearing and touch. The sensitivity of their whiskers enables them to move around at night confidently in complete darkness using these senses. This is why it is rare to see them during the daytime. They have poor eyesight which means they cannot see detail but can detect shape and movement in dim light.
Commercial buildings such as offices, warehouses, hotels, supermarkets and food processing plants have numerous potential weak points that can be exploited by rodents.
Each part of a building has different risks for entry, harbourage and providing access to other parts of the building. Poor building design and maintenance give rats and mice opportunities to enter buildings and get around them in numerous ways. Their intelligence, curiosity and agility mean that if there is a weak point they are likely to find it.
Weak points in the structure of buildings that allow rodents entry include:
A survey to assess a rodent infestation involves a systematic inspection of the building and surrounds to look for the signs of rodents:
– Droppings: Mice and rats produce large numbers of droppings: mice about 80 droppings per day and brown rats about 40
– Dirty smear marks along their runs made by their oily fur
– Gnawing damage around holes, cables, packaging, or on food products
– Rodent runs – routes commonly used to travel around a property
– Nests and harbourage – any undisturbed space or corner in a building can be used, such as roof voids, underfloor spaces, ducting, cavity walls, inside stacks of foodstuffs
– Live or dead rodents
– Smell — mice urinate frequently which creates an ammonia-like smell
– Noises of rodents scampering, gnawing, scratching and squeaking in hidden places
Finding out where the rats and mice are located and where they are active in an infested building is one of the essential tasks in planning control measures. For decades pest controllers have used a simple powdery substance, generically called tracking dust, to show where rats and mice are running around.
Tracking dust consists of talcum powder, flour or china clay, but more recently a range of branded products, some with fluorescent dyes, have entered the market. These should not be confused with toxic tracking dusts that are designed to kill rats and mice after they swallow the dust when they groom themselves.
Tracking dust is simply scattered on a floor or flat surface where rats or mice are suspected to run and left overnight to see if tracks appear. Tracking dust has limitations, however. It can be difficult to spread and clean up and should not be used where the dust can drift and contaminate food. Also, it can only be used on smooth horizontal surfaces.
As described earlier, rats and mice are agile creatures and don’t stick to smooth flat surfaces to find food and shelter in buildings! Considering all the structural weak points in buildings listed above, it can only be used in a limited number of risk areas. This is where Rentokil’s new Fluorescent Tracking Gel leads the way in highlighting rodent activity.
Rentokil’s innovative Fluorescent Tracking Gel is a specially formulated non-toxic fluorescent gel that can be applied to virtually any surface where rats and mice can run or climb. The gel is painted onto a surface using the applicator in an area where there is evidence of or suspected rodent activity. The gel does not dry out and when the rodents run over it or climb on a surface where it has been applied, it sticks to the feet, belly, and tail.
The rat or mouse then leaves a trail of the gel wherever it goes. The fluorescent dye in the gel lights up when a UV torch is shone on it by a Rentokil technician, highlighting rodent trails in a building. This gives a good indication of where to put traps or bait and helps to determine control measures to take and advice for customers to prevent further infestation.
The gel’s properties make it far more versatile than tracking dust. The built-in brush in the applicator makes it easy to apply gel in a controlled and precise way on surfaces such as shelving, beams, around holes and restricted places where rodent activity is suspected. The gel is easy to remove with a wet cloth or sponge, or scraping tool, when no longer required.
The gel has been certified as food safe by HACCP International. This confirms that Fluorescent Tracking Gel can support the integrity and safety of food and complies with food safety legislation and standards endorsed by the Global Food Safety Initiative.
The gel can safely be used in splash and spill zones in areas where food is handled in businesses, such as in kitchens and food processing areas.
