4 Ways To Identify Cockroach Eggs

by | Jul 17, 2023 | Roaches

Look up some pictures of American cockroaches. Gross, right? In fact, all of the most common roaches you’ll find across the States – including the German and Oriental cockroaches – make you wince. But why’s that? Is it just the flattened bodies, the long thin antennae, the spiny legs? No: it’s also the fact that cockroaches are absolutely filthy, the secretions smell, their bites are painful and can cause allergic reactions, they creep about silently at night, and we somehow know instinctively that they carry horrible diseases. Cockroach eggs, on the other hand, are something else. But what does a roach egg look like, and why should we be especially worried?

What do cockroach eggs look like?

So why don’t cockroach eggs gross us out? Well, it’s pretty simple. Because while an American cockroach – or any other cockroach, for that matter – may remind us of disease, or a terrifying tarantula, or a repulsive centipede, roach eggs look like:

  • Reddish-brown grains of rice
  • Tan-coloured capsules
  • Oval-shaped beads or mustard seeds
  • Small, dark-colored lentils
  • Miniature coffee beans.

Not exactly terrifying, right? Well, think again. If you see an American cockroach egg laying about the place, that means you’ve got a population of healthy, reproducing roaches nearby. And not just that, that roach egg casing can trigger your asthma and other allergic reactions, give you diseases like salmonella and gastro, give rise to an army of filthy roaches that spoil your food, spread bacteria and pathogens all over the place, and generally just make us miserable.

What do cockroach eggs look like – and how else can we rapidly identify them? It certainly sounds like we need to know!:

1. Visual appearance

They’re small, their protective casing (called an ootheca) is oval-shaped, and they’re somewhere in the region of reddish-brown or tan, depending on the specific species.

2. Location

You’ll find cockroach eggs in places that are dark, warm, and secluded – and probably strategically placed near potential food and water sources. So, start looking in crevices, cracks, and corners of cabinets, walls, and even appliances.

3. Cluster formation

It’s rare to find a single cockroach egg and no others nearby. That’s because they lay those eggs in clusters – bearing in mind that every single ootheca houses multiple eggs.

4. Ootheca structure

Remember, the egg capsule is called an ootheca, and it’s simply a protective casing for up to 50 cockroach eggs at a time. Apart from looking like mustard seeds or small coffee beans, it’s elongated with visible ridges and grooves.
