Woodlice (Roly-Poly and Pill bug)

He lives in Spain !

Either kill them yourself or call an exterminator. :)

But determine why they are there. An occasional, solitary woodlouse has probably crept in by accident, or been carried in on something. If it's an infestation you are dealing with then merely killing the animals is shooting the messenger, for their colony indicates damp and decaying timber (their food).

Woodlice have a type of blood known as hemolymph, which is typically clear or pale yellow in color. Unlike vertebrates, woodlice do not have hemoglobin; instead, they use a copper-based molecule called hemocyanin for oxygen transport, which can give their blood a bluish tint in some cases. However, in general, their blood is not vividly colored.

These Creatures lack strong enough vocal chords to perform such strenuous activities. (If you are asking me to play along with a little kids joke, then they open their mouth's and go on a show that Idolizes Americans, and if this is some sort of riddle, then the answer is: they rock and roll.)

A colony consist of up to 20~40 woodlice.
