What Do Roach Eggs Look Like?

Everything starts with an egg.

A pregnant roach arrives at your home and searches for a hidden place to lay its eggs. Around two or three months later, depending on the species, the egg (or eggs) hatch and dozens of nymphs (little roaches) are running through your home spreading diseases - you have an infestation.

This situation is completely avoidable with the right information and some work from your side. An important factor for you is that once you see anything that even looks like a cockroach, a baby cockroach, or an egg, take immediate action!

Where Do Cockroaches Lay Eggs?

If you have found an egg (these capsules are actually called oothecas) by cassuality; probably it will be more because a roach can lay several oothecas in just a few days. It is better that you find them right now. The most common places where a roach lays its eggs are:

  • Interior and exterior pipes
  • The foundation of the home
  • Small cervices
  • Walls or cracks in the walls
  • Cabinets, etc.

Keep in mind that the female cockroach will search for a hidden place without light, and preferably, warm to save its oothecas. You must analyze your home to find these places.

Depending on the aspect of the ootheca, you can differentiate between the most common species of cockroaches. The German cockroach, the American cockroach, the oriental cockroach, and the brown banded cockroach.

Let's take a look at them.

German Cockroach Eggs

  • Size: six to nine mm.
  • Time to hatch: -
  • Quantity of babies by ootheca: Up to 50

  • Time to hatch: 45 days
  • Quantity of babies by ootheca: nine to 10 babies
  • Infestation size: Between 54 to 900 cockroaches

  • Ootheca color: Dark reddish-brown
  • Size: 10 mm
  • Time to hatch: 80 days
  • Quantity of babies by ootheca: Approximately 16
