Cockroaches are the oldest surviving insect form on the planet and the United States is home to about 70 different types of cockroaches. Some of the common roach species we find in the US include the American cockroach (Periplaneta americana), Oriental cockroach (Blatta orientalis) and Brown Banded cockroach (Supella longipalpa). Dating back nearly 350 million years, cockroaches are notorious for being extremely difficult to get rid of indoors. Besides being a nuisance and frightening people, there are more harmful reasons why cockroach control is a necessity when you first spot the signs that you may have an infestation. Roaches carry disease-causing microorganisms on their bodies that can contaminate surfaces and foodstuffs. 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, cockroaches are the number one cause of allergies among inner city children, and 26% of the US 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.
