Hi, I would appreciate your help about this matter.

I found at home some of these insects shown in the pictures below..
It's darkbrown-black coloured ( in the last 2 shoots  it appears red-
orange due to the flash light of my camera).

They should look like fleas, but they didn't jump when I caught them
(as fleas should - they were only "walking" on the floor).
If I'm not wrong, fleas are quite hard to crush and this is not the
case.

Here are the links of the images

I would like to know what are they and if they should be dangerous (in
this case I suppose I should make a disinfestation or something
similar).

Thanksa lot  for your attention and help.

Hello!

> I found at home some of these insects shown in the pictures below..

If you don't tell us, where in the world that home is, no one will
be able to tell you exactly which species these beetles are...

Here in central Europe we have only one similar looking species,
'Gibbium psylloides' (family Ptinidae). But in America, Australia,
Asia (...) there may be others looking like it.

thanks a lot for the info.

I live in northern Italy...

I forgot to mention the size of these insects: 2-4 mm I think

So I suppose they shoulb be the ones you told... are those insect
parasites or dangerous? Should I make any disinfestation?

thanks again for your help.

Not dangerous or parasites, but they can be a household pest, especially
when occuring in larger numbers. The beetles and their larvae eat nearly
all kind of organic material.
Sorry, I am no specialist and can't tell you, whether a disinfestation
is necessary or whether it would be sufficient to find the source and
remove it.

Looks like what i have: a shiny spider beetle as Juergen points out.
I'm fighting them myself  and the bug-buster just came this morning to
disinfest.

Read more about them here:
http://www.ento.psu.edu/extension/factsheets/spiderbeetle.htm

They are totally harmless (they like fabric and dust) but still
annoying as i find them crawling on my bed (the bed itself has fabric
all around), especially at night (their main activity timeframe).

I find they are coming from the floor as i have crappy parquet in my
bedroom with some spaces between the wooden tiles. Not much I can do
since the appartment is not mine and i cannot remove the floor ;-)

The problem is that, as you can read, every female could lay 100 eggs
so it could take as little as 10 of them to make 1000 and then you'll
start noticing them! I had plenty of them below the bed and in between
the bed and its shoulder.

If you find a way to get rid of them update this thread.

Lorenzo

P.S To the experts out there: is there any other insect that could
fight them and be more manageable (easier to get rid of once it has
done its job?).
