This molting behavior happens anywhere from ten to thirteen times until they become a full-grown adult cockroach. After their final molt cockroaches reach their final life cycle form—the adult. Adult cockroaches are equipped with wings and reproductive capabilities and are typically about three inches in length.
Fully grown, American cockroaches are a reddish-brown color and live up to about one year. More favorable conditions lead to rapid population growth while unfavorable conditions cause adults to develop slowly or even die early on. Here are a few signs that you might have American cockroaches somewhere in your home. American cockroaches typically leave droppings where they hide.
This can be anywhere from basements and garages to pantries and behind appliances. Though these droppings are small, they often carry disease causing organisms.
These organisms can contaminate your food, eating utensils, and food preparation surfaces. Identifying a cockroach ootheca, or egg case, is actually not such a bad thing!
The egg casings contain just the eggs of the cockroaches, meaning you can get rid of the cockroaches before they hatch. Egg capsules are about 38 millimeters long and are typically a reddish, black color. They are commonly found in basements, laundry rooms or kitchens and behind appliances or under cabinets.
A good precaution to take is checking these areas around the summertime. Though cockroaches are around all year long, they typically take refuge in homes when the weather is hottest.
The odor of the chemical helps cockroaches identify each other which causes them to stay together in groups. It takes cockroaches about one to two months to hatch, though the egg stage can last from 14 to days depending on species and climate. In general, the higher the temperature, the quicker the pests develop. Most females create multiple egg cases during their lifetimes, so infestations grow rapidly. For example, one German cockroach can produce over eggs in a year.
Nymph Next in the cockroach life cycle is the nymphal stage. Nymphs hatch and undergo several molts, growing a little each time they shed their skins.
As they emerge from their old shells, immature pests have soft, white bodies that harden and change color to brown, tan, or gray. They will reach full adult size and coloration with their last molt.
