Different Types Of Roaches


Are Cockroaches Harmful To Humans?

Cockroaches are filthy pests that can spread disease, contaminate food, and cause allergies! The allergens left behind by cockroaches are often very irritating to humans and have been known to cause sickness, allergies, diarrhea, and even asthma in children. A cockroach can survive for more than a month without food or water and over 45 minutes without air.


It is often said, “For every one cockroach you see, there are 1,000 more in the walls.” Unfortunately, this is more often true than not as cockroaches reproduce very quickly and prefer dark, secluded areas, for example, behind stoves and in the walls. Cockroaches will eat almost anything, but favor greasy, sweet foods left behind in the kitchen. When one cockroach discovers food, it releases a chemical into its feces which will guide other roaches to the find.

Most roaches are oviparous; their young grow in eggs outside of the mother’s body. In these species, the mother roach carries her eggs in a sac called an oothecal, which is attached to her abdomen. The number of eggs in each oothecal varies from species to species. Many female roaches drop or hide their oothecal shortly before the eggs are ready to hatch. Others continue to carry the hatching eggs and care for their young after they are born. Regardless of how long the mother and her eggs stay together, the oothecal must stay moist in order for the eggs to develop. Newly hatched roaches, known as nymphs, are usually white. Shortly after birth, they turn brown and their exoskeletons harden. They begin to resemble small, wingless adult roaches. Nymphs molt several times as they become adults and the period between each molt is known as an instar. Each instar is progressively more like an adult cockroach. In some species, this process takes only a few weeks but in others, like the oriental cockroach, it takes between one and two years. The overall life span of cockroaches differs as well – some live only a few months while others live for more than two years.

Cockroaches Love The St. Louis, Missouri area Climate And Once They’re In Your Home, It Can Be Nearly Impossible To Get Them Out

The cockroach is one of the most common and hated insects around. This species of bug has evolved to adapt to a wide range of environments, and is found in humid, tropical regions all over the world. The St. Louis metroplex isn’t tropical, of course, but cockroaches can survive in nearly any warm climate (and some cold climates, too!).

Cockroaches travel to the St. Louis metroplex from all over the world in luggage, airplanes, long-haul trucks, and shipping containers. The pests or their eggs can make their way into your home unnoticed through grocery bags and other packages. The cockroach has adapted to live in urban areas, and they are some of the worst pests to have in your house.

The cockroaches’ ability to reproduce as rapidly as every three days means that the population can soar within weeks of the initial entry. Roaches can adapt to nearly every situation they encounter, so they are difficult to eliminate.
