The American cockroach will reach 2 inches at full growth and can fly. However, their flight looks something like a drunken pilot with no concern for stick or throttle control; not the most graceful flight pattern you will admire in nature. The American cockroach’s primary diet is dead or dying organic material. Yard clipping, mulch, bark, fallen leaves, all of these items makes up the staple of American roaches diet. This diet is shared with the other three exterior roaches, the Oriental and the Turkistan. The major difference between the American and the other two roaches is their breeding potential. The American cockroach needs a full year to develop from its first instar (baby roach) through its final instar (adult roach). This is important in pest control because it can offer an opportunity to extend service coverage from monthly to bi-yearly in some cases. While they are the largest roach in St. George, in the opinion of the bug guy, this is the best roach to have.
