Yep, as disgusting and nightmarish it sounds, this is actually how a roach infestation begins.
And even though there are now many remedies available to eliminate this problem, you first need to understand what exactly you are dealing with, and this article is here to help you do that.
Keep reading to find out everything you need to know about cockroaches’ eggs and how to get rid of them.
What Does Cockroach Eggs Look Like?
Cockroaches lay multiple eggs at a time, and these eggs are all inside a single casing known as ‘ootheca.’
The egg capsules are usually dark-brown to reddish-brown in color and range from 5 to 14 mm long, depending on the species of cockroach you are dealing with.
Despite what some people believe, cockroaches’ egg cases can be spotted and seen with naked eyes.
However, they can sometimes be overlooked because they are glued to or deposited in hidden places that are not easily visible to us, like under wooden furniture, behind photo frames, etc.
Finding an egg case is a sign of infestation in the home.
American Cockroach Eggs
One of the most common cockroach species is the American cockroach; they prefer warm and damp places and usually enter houses to find water and food.
Female American cockroaches, during reproduction, create shielding cases for their eggs.
These cases are shaped like capsules that are deposited by the female cockroaches in a humid, warm area.
An average American cockroach egg case contains about 16 to 17 eggs, and when they hatch, tiny nymphs come out of these capsules.
The cockroaches emerge from eggs in 6–8 weeks and need 6–12 months to mature.
These egg cases are about 35-38 mm long; they are dark-colored—blackish or reddish-brown.
People usually find these egg sacks in basements, kitchens or laundry rooms, under cabinets or appliances, etc.
American cockroaches also deposit their eggs behind stored items in sheds and garages.
German Cockroach Eggs
The German cockroach is another concerning pest that reproduces very quickly and efficiently.
The female carries the developing eggs inside the capsule and deposits the capsule right before the eggs hatch.
A German cockroach’s ootheca is brown-red in color and mostly measures between 6 to 9 mm in length.
The female cockroach carries around the ootheca until the eggs inside it are ready to hatch.
After depositing the egg sack, the females can start producing more eggs in a couple of weeks.
One single ootheca can accommodate up to 50 nymphs.
Female German cockroaches can usually produce between 4 and 9 egg capsules in a lifetime and for an egg to develop into an adult usually takes up to 103 days on average.
Because German cockroaches can produce multiple egg sacks containing large numbers of eggs, populations can grow rapidly in a relatively short period.
A typical German cockroach infestation will contain around 75% of nymphs in the population.
