Rodents have constant growing incisors in their upper and lower jaw, to wear them out, they need to gnaw. Railways are most infected by pest like rodents, termites, cockroaches, bedbugs etc. Rodents and other pests also spread diseases such as Leptospirosis, bubonic plague, Salmonellosis, rat- bite fever, dysentery, typhoid, poliomyelitis, gastroenteritis and skin infection. Thus they are a threat to passenger’s health. The Indian Railways spend about Rs 60,000 every month to get rid of the rodent menace.
Termites are small organisms of about 4-15 mm long and vary in color from white to tan and even black. Termite’s bodies are divided into three parts- head, thorn, domain and six legs. They eat 24 hours a day and seven day in a week. Termites cause $2 billion in damage every year.
Rodents and termites are a threat to the railway sector. Indian Railways is operated by government of India through the Ministry of Railways. It is one of the world’s largest railway networks comprising 115000 km of track over a route of 65000 km and 7500 stations. About 25 million passengers travel daily and 2.8 million tons of freight is transported. Indian Railways collect revenues of about Rs 111984 crore.

Many conventional methods are used like fumigation, glue boards, rodents traps to control the nuisance created by rodents, but these methods are proved worthless. Also these methods are unhygienic as well as toxic to humans as they contain harmful chemicals. As glue board cause slow death to the rat and they slowly decompose, it leads to an unhygienic environment. Glue board is also not very effective if exposed to the moisture.
Combirepel®™ is a product manufactured by the C-tech Corporation which is non-toxic, non- hazardous and eco-friendly. Combirepel®™ is a blend of Rodrepel®™ and Termirepel®™ and is applicable for use against both termites as well as rodents.
Rodrepel®™ is a non-toxic, non-hazardous and eco-friendly anti-rodent aversive. Termirepel®™ is a non-toxic, non-hazardous and environmental safe anti-termite and anti-insect aversive to keep away termites and insects.
In Railways, Combirepel®™ is used in lacquer based form by mixing it with the lacquer or in a paint compatible form.
Combirepel®™ is tested on various railway zones- south-western zone, Konkan zone, Northern zone and central zone. It was tested extensively in the Northern Railway as it is the biggest in terms of network having 6807 km route. Four coaches were used for the testing, 1 pantry car and 3 AC coaches. The coaches are painted in 3 stages- the painting of the under carriage, the painting of the body panel and the painting of the interiors. The galvanized surface is painted with lacquer based paint. The interiors of the coach, body panel, doors, lavatory passage, window sides, seat sides and seat corner were also coated with the Combirepel®™ and the complete inspection are carried out every 2 months.
The pantry area is mostly attacked by the rodents due to the presence of food. The pantry area, resting area of passengers, the lavatory and the storage area were painted and checked.
No sign of infestation was noted. There were no pests in the storage rooms where mostly roaches and insects are found due to the darkness. There is a large difference noted in the numbers of rodents, termites, roaches and other insects after the treatment with Combirepel®™. It is also very safe for pantry cars and other sensitive areas as it is non-toxic.
Its application is very easy and effective. Combirepel®™ is mixed with lacquer in a ratio of 1:100 by simple mixing and the surfaces are painted. The mixture is blended by blender before application for uniform mixing. The paint is applied on the surfaces to be coated in uniform manner. Wooden surface and walls are painted with 1 coat; while on galvanized surface 2 coats of paint are used.
Combirepel can be used as an effective solution for the pest problem in railways.
