Due to their relatively small diameter, optical fibers are more susceptible to rodent attack than traditional telecommunication cables. Rodents cause lots of maintenance problems by cutting and destroying wires of telecommunication and transmission equipments.

Rodents chew because they must (their teeth continue to grow during their lifetimes and must be constantly worn down) while deer and other animals chew in search of food or out of boredom. Whatever the reason, the very act of chewing damages the wires or pipes rendering them useless –or worse, creating situations like the New Zealand Stock Exchange which was forced to close down for several hours after rodents chewed through a fiber-optic communication cable, leading to the collapse of the country's telecom network for 6 hours.

Subterranean termites and other insects are also known to feed on wires and cables which may be laid underground for transmission of information and communication purposes. This can expose wires and lead to short circuits. The Termite Prevention and Control Research Institute has studies reporting that insects also damage wires and cables made from copper, iron and aluminum. Hence the damage done to wires and cables needs to be addressed.

Conventional insecticides/rodenticides cannot be processed be with these wires and cables as they aren't meant for polymer processing temperatures often leading to toxic fumes which are a hazard to workers handling the processing of wires and cables. CombirepelTM combines the need to deal with these pests combined with the need of having a non toxic and non hazardous additive for the telecommunication industry.

Gas pipelines especially the ones which are used in the city gas distribution systems since they are made of polymeric material are vulnerable to attacks by aggressive subterranean termites as also other insects.

These applications are especially sensitive since they are used for hauling natural gas over long distances and thus can lead to a potential disaster in case of a gas leak. Hence insect/termite proofing of the gas pipeline needs to be done effectively.

They are also disturbed by chewing of rubber gas tubings and pipelines. This has now compelled the pipeline and rubber tubing manufacturers to fabricate products, with anti- rodent properties, complying with government specifications. Times online, UK News, had reported the death of an old lady due to gas explosion. Gnawing rodents were to blame for the death of an 80-year-old woman in a massive explosion that flattened her home. They had gnawed through her kitchen rubber pipes, causing a build-up of gas in the room.

Rodents significantly damage crop before and after with an estimated 20% of the world's food supply consumed or contaminated each year. Rodents have two major impacts. The first is the substantial pre- and postharvest losses they cause to agriculture.

The second is as carriers of debilitating human diseases, insects are most often responsible for damaging crops as it eats leaves or burrows in stems, fruit, or roots. Losses to the tune of 10,000 hectares of paddy crops getting destroyed due to insects and worms have been reported in areas like Bhubhaneshwar, Orissa. This requires that the problem of insects be addressed in an effective manner.

Drip Irrigation & Pipelines (pre- harvest losses):
Drip irrigation, also known micro- irrigation, is an irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of plants, through a network of valves, pipes, tubings, and emitters. However, the whole purpose of conservation of water using such systems turns futile if these tubes get vulnerable to rodent/insect attacks. Some farmers despondently state that "for every eight rows of rice they sow for their families, they sow two rows for the rats." Thus it is essential that the drip irrigation pipelines/tubings are made anti-rodent and anti-termite/insect.

Storage containers and bags (post- harvest losses):
Rodents have an enormous economic impact on stored grain in developing countries. Under traditional rice farming systems, rodents generally cause chronic losses to production in the order of 5–10% per annum. In Asia, a loss of 5% of rice production amounts to approximately 30 million tonnes; enough rice to feed 180 million people for 12 months. Moreover, rodents are carriers of more than 40 diseases like Leptospirosis, Salmonellosis, Plague (Epidemic disease), Trichinosis etc.

According to a 1990 survey of extension specialists throughout the United States, stored grain losses exceeded $500 million for the year. Most of these losses resulted from infestation by several species of insects and damage by numerous molds and mycotoxins. Similar losses have been reported over the years in various countries. These losses need to be minimized/nullified. Plastic bags which are incorporated with CombirepelTM can be used to tackle this menace thereby reducing losses of the stored grain.

A termite barrier is a physical object that keeps termites from penetrating the foundation of a house or accessing other parts of the property. Termites are wood-destroying pests most commonly found all over the planet.

New developments and centrally heated homes all over the United States, Europe and Australia have made them the breeding centers of termites. According to Bjostad, termites cause $22 billion in structural damage annually around the world. This includes $11 billion in annual damage in the United States, including damage in Colorado, where many residents are unaware of termite infestation. The estimated cost of termite treatment is 200 million Euros per year. If added the cost of repairs, replacement or destruction of structures, furniture, walls and other woodwork, the annual cost in France would be around 500 million Euros a year. More and more countries are now heading towards a termite barrier system installed during the construction phase of the house. CombirepelTM can be incorporated in these termite barriers and thus used for protection of the houses from termites.

CombirepelTM can also be used as a wood preservative to protect household furniture from infestation from aggressive Formosan termites which are known to inhabit wooden constructions. The wood prior to use in the application can be dipped into a solution of CombirepelTM thus rendering it termite proof.

Passenger coaches often are infested with roaches, rodents and bed bugs and several other insects. This can cause great discomfort for passengers especially in long distance trains. Pantry cars are also vulnerable to cockroach and other insect infestation which can contaminate the food via droppings, wings etc. besides creating an unhygienic atmosphere.

Rodents often disturb underground train services and metro rail services. They are a menace for the passengers travelling in train especially in A.C. coaches. Thousands of complaints have been registered by people travelling in trains regarding rodents.

These problems can be addressed by the use of CombirepelTM by blending with paint and coating the same to the coaches.

World over heritage structures which are the symbol of pride for any country suffer the ignominy of being vandalized by birds who sit on these heritage structures and make a mess with their pecking, food habits and droppings.

CombirepelTM provides a solution by which these structures can be restored to their former glory! A customized application of CombirepelTM is possible by which it can act on certain receptors in the feet of these birds and thus effectively repel them and prevent them from approaching these structures paves the way for heritage structures to once again serve as a symbol of pride and glory.

The rodents have been a nuisance for the defense system. They move the underground laid mines from their original location creating a trouble for them to locate it again. They chew the cables and pipes also creating a problem for the defense to transmit information from one place to another.
According to study by the Defense Research and Development Establishment, Gwalior, India; the aircraft arrester system remains in open ground all the time, since it is used on runways.

It is damaged by rodents who by nature chew and cut materials and hence nylon tapes in open fields are susceptible to these rodent attacks. The rodents consume more than 50% of the nylon belt without any rodent repellent additive.

Many of us have had trouble starting our cars in the morning as a rat or a vole had eaten through the cable. Complaints of car shut-downs and engine damage are extensive and prevalent globally. And to add to the dilemma, rodent damage is not covered under most auto insurance schemes.

Another problem that has often been encountered for under-the-hood parts is that of overcrowding by spiders. This gained attention when Mazda recalled 52,000 U.S. Mazda 6 sedans because of spiders weaving webs in a vent line.

Many electronics companies has been trying to come up with new methods to prevent the cable and wiring of refrigerators from rodent attacks. They have developed anti- rodent sleeves using ROHS compliant polymer additives for such measures.
