Help: Is this insect dangerous ?

[e_lm_70]

Hi,

I got a house from a previous owner in Poland.

The man that was living before did left some wood in the garden, and since it was exposed to the "elements", it did got infested by these insects.

Unluckily since I use wood for heating, I need to accumulate wood in the garden (this is protected) but these insects did manage to find the way to my stored wood. And they look to multiplicate around my wood ... even if I can't see any wood damage in the wood that I store ...

Now, since the roof of the house is wood made, do I have risk that these insect could "attach" my house.
Even if the wood is stored next to the house, so far I did not find any of these animal inside the house or under the roof.

Thanks
