Cockroach vs. Bedbug: Difference Between Bed Bugs and Roaches

Cockroach and bed bugs both cause irritation when seen. Though there is a difference between both of them.

Let’s start with defining both of them in brief:

Cockroaches are an ancient group of insect dating back at least as the Carboniferous period, which can be considered as about 320 million years back.

They are flat and oval-shaped insects.

They can be almost found anywhere where there is an adequate supply of food.

Bed bugs are small, flat and oval-shaped insects. Bed bugs can’t fly and have no wings.

They simply rely on humans to carry them from one place to another. They feed on blood from humans or animals.

They are mostly active at night; they feed on their victims when they sleep.

It can also create a bit of larger bumps on your skin.

  • It can also cause a skin rash.

Final Words

In the end, I would like to conclude that cockroaches and beg bugs both are dangerous for health. They carry bacteria and often are exposed to the food which is eaten by us. So, proper cleanliness should be maintained. Proper ways to get rid of these insects should be taken in order to avoid diseases.
