I was reading Mikes readers blog about the purpose of mosquitoes and I wondered is there a purpose for roaches

Question

other than to gross us out and to be nasty? I mean what would happen if roaches just all died out? I know, I know they have been around a long, long time and it is said that they could survive a nuclear blast.

Answer 1

Cockroaches have same purpose just as other insects have, like -

1. Pollination.

2. Food for other animals.

3. Decomposer's of food and waste left by us.

Insects like cockroach are the most hated animals. They are also one of the insects that are most underestimated.

Every creature no matter how small/creepy/crawly/ugly it looks, has a purpose in the ecosystem.

I myself don't like cockroaches but i kill them only when it is absolutely necessary, they are pests after all. Anyway they are going to become the lizards dinner eventually.

But we don't understand them. There are many things to learn from them - Like -

They can survive eating anything.

They can live for weeks with their head cut off.

They can also survive radiation.

They are very adaptive and get immune to various insect sprays.

They have hard skeleton and don't die easily if you step on them.

These qualities of cockroach need to be studied and can be used for the benefit of humanity.

Though cockroaches are generally considered pests, only about 30 species (less than 1%) infest urban habitats, 55 species in total live in the U.S.
