Rats are the most detrimental pests found chiefly in unsanitary conditions. They are highly responsible for the transmission of many diseases like rat bite fever, Leptospirosis, Plague, Trichinosis, Salmonellosis and food poisoningas their feeding habits are destructive.
Rats cause a lot of damage. As the teeth of rodents continue to grow over their lifetime, they need to gnaw on hard substances such as lead and plastic pipes, insulation material and electric wiring. This habit increases the risk of short circuits and fires. In addition to this, they transmit a number of dangerous diseases such as Salmonella, Leptospirosis (Weil's disease), Tuberculosis and even tape worms.
