Asian Cockroaches

What do Asian cockroaches look like?

Asian cockroaches are small and look very similar to German cockroaches. Both are light tan to brown and have two dark, parallel stripes just behind their heads. They also share common features like six legs and long, slender antennae. That said, there are a few key differences between the two.

Asian cockroaches are slightly larger, measuring about ½ to ¾ of an inch long. One of the biggest differences is in their wings: while German cockroaches have wings that are shorter than their bodies, Asian cockroaches have longer, well-developed wings—which is why they’re strong fliers, unlike their German counterparts

What do Asian cockroaches eat?

Like most roaches, Asian cockroaches aren’t picky. They'll eat almost anything, from decaying plant matter and flowers to food scraps, starches, glue, and even other insects. Their wide-ranging diet makes them especially hardy and able to survive in a variety of environments.

Are Asian cockroaches dangerous?

The upside? Asian cockroaches don’t bite or sting. The downside? They’re still a health risk.

Because they feed on just about anything, Asian cockroaches often end up in unsanitary places—garbage, compost piles, or even dead animals. If they then make their way into your kitchen, they can spread bacteria and other harmful pathogens they've picked up along the way.

Studies show that cockroaches can carry and transmit more than 30 types of bacteria. Their droppings, shed skins, and saliva can also trigger allergy or asthma symptoms in some people.

How do Asian cockroaches get into homes?

Unlike German cockroaches, which are typically indoor pests, Asian cockroaches prefer being outdoors, especially in warm, humid areas with lots of vegetation. You’ll often find them in mulch, grass, compost piles, or leaf litter.

But since they’re excellent fliers, they can easily make their way indoors through open doors and windows. They might also come inside when outdoor conditions become less favorable or while searching for food. Thanks to their small size, they can slip in through tiny cracks or gaps in your home’s exterior.

Once inside, they tend to hang around if the environment is humid and food is easy to access. Bathrooms, kitchens, and laundry rooms are some of their favorite indoor spots.

Once inside, they might decide to stay if the conditions are favorable. Asian cockroaches are most likely to show up in your kitchen, bathroom, or laundry room since these rooms tend to have higher humidity than others. 

What are the signs of an Asian cockroach infestation?

Here are a few signs that may indicate you’re dealing with Asian cockroaches:

• Seeing live cockroaches: They’re nocturnal, so you’re most likely to spot them flying near lights at night.
• Shed skins or droppings: These are often found in hidden areas like under sinks or behind appliances.
• A musty odor: Large infestations can produce a noticeable musty smell.
