Colorado, a state which is located in the Western United States and experiences relatively cold temperatures, which makes cockroaches quite tough to survive. These cockroaches still find a way to somehow live in dark cozy areas. Though there are a lot of species of cockroaches in the United States, Colorado mostly has only three types, which are listed below.

1) German Cockroach

German Cockroach

Description

 Scientific Name: Blattella germanica

This cockroach is the most troublesome for households. These cockroaches are a significant worry as they like indoor locations. These are small in size, ranging from 1/2 inch to 5/8 inch in length and medium yellowish-brown in color. German roaches can be distinguished from other cockroaches by two dark parallel stripes on the anterior, dorsal portion of the thorax.

The preferred habitats by these cockroaches are Kitchens, bathrooms, and other locations that provide appropriate amounts of food, moisture, warmth, and shelter.

LifeCycle

The reproductive rate of these roaches is highest, among others. A female German bug lays 20 to 40 eggs at a time, with an average incubation spell of 28 days, and will produce around four or five oothecae in her life duration, which makes about 200 offspring. These go through six or seven instars before maturity. The development stage from nymph to adult takes an average of 103 days. Their average adult lifespan for both males and females is the same that is less than 200 days.

2) American Cockroach

American Cockroach

Description

Scientific Name: Periplaneta americana

American cockroaches prefer damp conditions and often are found in sewers, woodpiles, and mulch. This is a reddish-brown, about 1.5 inches long or longer than that, winged, but does not fly. The wings of males are longer than the female wings. Young cockroaches are gray-brown. 

As the American roaches mature, they become more reddish-brown in appearance. They have well-developed wings but do not fly much unless temperatures are above 85 degrees, then they are known as “flying water bugs.” These generally cannot survive in temperatures less than 25 °F.

LifeCycle

A female roach lays around sixteen eggs at a time and produces six to fourteen ootheca during her lifetime. The average incubation period is 44 days, which makes up to 224 offspring. American cockroaches go through 10 to 13 stages before adulting. This process of reaching adulthood takes an average of 600 days. Male cockroaches can survive up to 362 days, whereas females can live over 700 days.

3) Oriental Cockroach

Oriental Cockroach

Description

 Scientific Name: Blatta orientalis

 These are also known as Black Cockroaches because of their appearance. These are shiny black to dark reddish-brown. They are about 1 inch in length. 

They are most active early in the evening and are located at ground level. They often take shelter in basements, crawl spaces, utility rooms, sewers, and old incinerators as these places do not have frequent visitors. Due to the cold environment, they are commonly found under refrigerators, sinks, washing machines, and floors.

LifeCycle

 A female Oriental cockroach lays about 16 eggs in one time and will produce around eight oothecae during her life, which is roughly 128 offspring having an average incubation period of sixty days. These roaches go through seven to 10 instars before reaching maturity, and this development process takes about 589 days. Females approximately live for 180 days, whereas males have a shorter lifespan of about 160 days.

Conclusion

Cockroaches are tiresome pests that take a lot of hard work on the part of humans to get rid of once they infest our homes. Proper controlling measures should be taken, and hygiene should be maintained to keep cockroaches away.
