April 28, 2018

We all have seen a cockroach and may have even come across them plenty of times and every time most of us may have felt only one out of the two things - annoyance or a little fear. Many of us may also have wondered 'can cockroaches bite?' But one thing can be more or less a surety - that most people will not like their presence. Whatever we may have felt ourselves, but it is a known fact now that the insect is one of the most primitive winged creatures on the planet. There is data to corroborate that the insect has been there for more than 320 million years. At least 4600 species of the insect still abound the earth. The word cockroach comes from the Spanish Word Cucaracha. What attracted roaches to earth is still not very clear for researchers but one thing that is very clear is that they have a ‘never say die’ attitude, due to which they have been able to keep themselves afloat for so long.

Physical Characteristics of Cockroaches:

It has an oval flat body, a shiny brown or black leathery covering, and a long delicate looking antenna. Unlike other insects, the head of a cockroach is usually bent downward and all parts of its mouth point downward and backward so that it is quite typical of this insect.

People have always wondered, ‘can cockroaches bite?’ regarding its small mouth. In fact, the answer can be both a yes and a no. They generally like to eat vegetables and meat. There have been instances where cockroaches have been known to eat human flesh, both living and dead. Cockroach bites can be irritating or may produce a swelling. They may be expected to take a bite on feet, fingernails, hands or eyelashes. But these can only be in extreme cases. Usually, cockroaches are shy insects and may not show up easily, remaining confined within their area.

The Physical Structure of a Cockroach:


A male cockroach has a pair of wings whereas the female of most species may be devoid of it. In some species, the female may exhibit a pair of vestigial wings. A female cockroach is responsible for producing eggs in typical egg cases that are known as oothecae. Oothecae can be left protruding from the body of a female roach or can be glued in some protective area. After deposition of these oothecae, gentle white nymphs may emerge out of them. Initially, their body may be quite soft on the back portion but with the advent of time and growth, the exoskeleton may harden producing a brownish color. Most roaches, including the American cockroach, have a distinguishing body structure that is typical of the creature and though there are minor differences, they can be easily recognizable.

There are certain cockroaches that may have a wingspan as large as 4.7 inches and that can be quite massive for any insect! Due to their typical body features and certain distinct traits, the creature is very much desired in laboratory experiments to this date. A lot of research has already been done on it and many more are under study. Queries like 'can cockroaches bite?' and 'can they be alive in all-weather's?' still abound the zoological circles.

The Diet and Living Environment of Cockroaches:


Cockroaches generally prefer to live in a dingy, warm and dark environment. This small insect can be expected worldwide to be present in a place that has sufficient moisture so that breeding becomes easier for it. It is also the reason why these are abundantly found in mild and tropical climates throughout the world. People generally ask ‘does water attract roaches?’ and the answer is a definite yes, as long as there is no flooding. Though there are some varieties of cockroaches that can actually be alive even under water for a few minutes like the German Cockroach, that has the ability to stop breathing for a few minutes!

Unlike popular perceptions, there are only a few species of cockroaches that can actually be considered as pests. However, it also must be mentioned here that wherever this creature lives, it can thoroughly emit a pungent smell and that can be a huge turn-off for anyone. Moreover, the insect may damage more materials compared to what it consumes itself and therefore a lot of trash can be created by it. As to the question, ‘what attracts cockroaches in your home?’ there can be a lot of answers but then people must maintain cleanliness all around a place so that there is no accumulation of dirt and dust.

An American cockroach and many other insects like living inside wall and hole cavities. Therefore, it can be worthwhile to get rid of these holes and cracks, especially if one lives in a shared apartment. It is because neighbours may not maintain the same level of hygiene and cleanliness and it can be worthwhile to take care of them independently. Hence, any fissure in between a wall and countertop, baseboard and the pantry should be kept sealed. This can take some time but results can be long-lasting.

The Vision of a Cockroach:

With regard to its eyes, all types of roaches, including the German cockroach, have compound eyes, as in every other insect. Some of them may get attracted to lights at night but mostly, they keep themselves confined to the soil and are mostly nocturnal creatures. The antennae of a roach help it to find food and make its way through. Therefore, it can be one of the most important organs of its body.  

The diurnal species of roach can be found in shrubs and foliage of trees. Most species of cockroaches are unconnected to mankind but some of them like Panesthia Regalis and Theria Petiveriana can be quite beautiful due to the alternate orange band on a dark body and with superb spots of white.


The life cycle of a cockroach can be quite varied as it initially starts from the egg, goes through the nymph and finally develops into an adult. In most species of roaches, they can easily live more than a year. Certain species of roaches are known to live from one to four years too. Moreover, it can stay in many different types of climatic condition, vegetation, and circumstances.
