Cockroaches are the oldest surviving insects on the planet. India alone is home to about 30 different types of cockroaches. Some of the common roach species we find in North India include the American cockroach (Periplaneta americana), Oriental cockroach (Blatta orientalis), and Brown Banded cockroach. Cockroaches are also a major concern due to the fact they produce several very potent allergens that have been linked to the development of asthma. In fact, 6% of the Indian population is said to be allergic to cockroaches. Fortunately, research has proven that good cockroach prevention and control can reduce the level of those allergens in infested buildings.
