Question: I am dealing with woodworms at home and I am looking for an effective method to contain their spreading and eliminate them from my furniture. 
I would just like that they chose another place to build up their home, that should not be my flat!!!

The woodworms are in my furniture since 5 years more or less. I have at least 5 wooden pieces of furniture occupied by woodworms. They are mostly chairs, a showcase and a chest. I figured out that they were woodworms because of the sawdust and the little holes left in the wood.
What happens is that these tiny animals move from a piece to another and every year a different piece of forniture is contaminated. 

I did not call a pest control and I had ever dealt the situation on my own. What I did since now it has been to inject a solvent with a syringe inside the holes in order to kill the eggs that they supposedly laid down inside the hole.

However now I am a little bit worried because in this season (spring) they are growing up a lot and spreading in my house and because they started getting inside 3 uncontaminated wooden doors I care a lot about.

Now my request is the following: could someone suggest me some effective methods to prevent their spreading?
I know it may sound strange, but does someone know the habits of these little animals? Or does someone knows a useful book or guide to face against them?

I am able to contain the emergency injecting the solvent in the holes, but I definitely cannot figure out how and where they lay down the eggs. This could be very useful because I would be able to prevent them dig their hole. 
Indeed I understood that the big hole we can see in the wood is the exit hole, while the entrance hole is a tiny one, almost not visible unaided eye.

Thank you to everyone!

Answer: 
You can use a left over matte finish (I'm guessing this is what you were talking about), but the blocks will soak it up and you may need a few coats for a decent look. I would start with a masonry primer first that will seal and fill the pinholes, then you can topcoat it with whatever you want. 

You can paint the floor, but you're going to have give more information: Is it new concrete? Is it stained or sealed? Is it painted right now? Do you plan on parking cars on it? 

H&C Shield-Crete and the Acrylic glaze to go over it may be your best bet.
You could also used watered-down PVA glue to seal up the pores in the concrete and prime the surface for paint, as this is a cheap and effective way of doing this, and will reduce the amount of paint you need for good coverage.

Note that regular PVA cannot be used to prime surfaces prone to dampness or getting wet.
