No, crickets and cockroaches are not related. Both insects may be classified together depending on how the grouping is done. They also have a few similarities, but many kinds of research have shown that the two are not closely related by any means.

Have you ever observed the similarities between crickets and cockroaches and wondered if these insects are closely related? Well, you are not alone in your curiosity, as millions of people worldwide have had the same puzzling thought at one point or the other.

This article will address your query by showing the several similarities and differences between these true insects.


Crickets are insects that belong to the orthopteran group that consists of long-jumpers like grasshoppers and locusts. Although “cricket” is often used as a general term to describe related insects, the typical cricket is quite different from bush cricket and others.

Crickets are most famous for their unique chirping sound, and this is arguably its most distinct feature. But it would surprise you to know that only males chirp and female crickets do not share this disturbing sound. In fact, the chirping sound is a communication method used to attract females and ward off close competitors.


Cockroaches belong to a group of insects called the Blattodea, along with termites. There are different species of cockroaches, totaling up to about 4,600. Several species are household pests, including the Australian and American cockroaches.

Cockroaches often come in different sizes and shapes, depending on the specie, but the majority of them are about a thumbnail large. Cockroaches have several unique features, but their resilience and adaptability often help them survive harsh conditions. They are often attracted to food crumbs and dirt piles, and they can eat almost anything.

Cockroaches and crickets may be two different insects belonging to separate groups, but they share enough similarities to prompt an inquest over their relationship.

Here, let’s take a look at some common features of both insects.

  • Appearance: Although the resemblance may not be striking, you can easily mistake one for the other when they make a scurry past you in the dark. Both insects are brownish, and each has six tiny legs, which makes it more difficult to tell them apart at a glance.
  • Antennae: Both insects have clearly visible antennae, perhaps adding to their similar appearance. Like most other insects, cockroaches and crickets utilize their antennae as their primary sensory organ. They can smell, feel surfaces, and tell temperature changes with this remarkable organ.
  • Feeding Habit: It is true that crickets prefer grass habitats which are quite contrary to cockroaches that can live anywhere. But they are both most attracted by food sources which are often either organic matters or plants.
  • Pest Behaviors: Because these insects are attracted to organic matters, they often find their way to homes in search of food. Once they get into your house, they often settle in quickly and reproduce immediately. Hence, their status as household pests.

Differences between Crickets and Cockroaches

Cockroaches and crickets may share some qualities that paint them similar, but these insects are very much distinct. Their key differences include;

  • Appearance: Indeed, the two can be said to have a lot more similarities in their appearance. But some contrasting features still sets them apart from the other. Firstly, cockroaches have a shell-like exterior as a protective layer for their wings and soft bodies. Crickets, on the other hand, have two front wings and two other hinge wings underneath them.
  • Habitat And Feeding Habit: Crickets often make their home in grass lawns and low bushes to have their fill of grasses. But cockroaches prefer moist surfaces where they can easily find organic materials.
  • Mating Habit: Both insects are known to be rapid reproducers, but they have a distinct mating habit. Male crickets call out to nearby females by making chirp noises, while Cockroaches flap their wings and make hissing sounds.

Are Crickets and Cockroaches Dangerous?

Yes, cockroaches and crickets can transmit diseases to humans, especially when you let them contact your food. Both insects can bite too, but it is very rare to see them attempt to bite humans except in cases where they are many with limited food sources. However, you can rest easy knowing that their bites are not fatal and may only cause temporary itching.
