Wood – Dealing with woodworms

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!
