1 is the beetle Molorchus minor (Coleoptera: Cerambycidae)
2-in nature, the larvae of this beetle live in pine trees, such as pine, fir. I got into the apartment by accident, most likely with some coniferous building materials. It is not dangerous for humans, but it can damage wooden structures made of coniferous wood. How to get rid of it? Etch the room with intexicides (I do not know such an insect that could survive dichlorvos. But it is best to use more modern means, for example, from the group of synthetic pyrethroids.). Given that it's winter, you can wait for severe frosts (January is just around the corner) and send all the wooden things where the beetles have settled to the street, in the cold. From a sharp temperature drop, the beetles will die themselves.

I am more and more inclined to believe that he came along with the construction of the sauna. There are no conifers there (at least, I think so).
I can't take out the sauna in the cold.
Poison dichlorvos (or other drugs) is also not particularly desirable. Sauna after all.
Maybe they'll die themselves? 90 degrees of heat, apparently, they tolerate well:- ) They have SUMMER.

Thank you for your quick response. I'm not an expert, but I compared the image on the Internet. The surface of "our" beetle is smoother, and in all the photos on the Internet it is more prominent.
Tell me, can these beetles (or their larvae) cause serious damage to the wooden structures of the house? And if so, what should I do?
Thank you in advance for your response.

If the population is large, they can do a lot of harm. Most often you have to deal with a similar problem on the roof crate, because almost everyone drives an unedged board there and does not clean the bark from it. To avoid further settlement, sand all boards as much as possible and treat them better with "Kartocid-compound - wooden doctor". The tool is not cheap, but everything else is just nonsense or very dangerous (believe my rich experience in this matter

for several years I have been processing houses throughout the Tambov region)

Road wasp (family Pompillidae). I got into the house by accident.

Thank you very much. Just the same mountain from the shoulders)

Why is it disgusting? Very cute insect. Read Fabre or Khalifman on the life of wasps. It will be more interesting than some bipeds. About the definition, or a road wasp, or a rider, like that: http://homepage.eircom.net/~hedgerow14/may30.htm. Give a macro photo of the object.

Thank you, I'll read it! Unfortunately, there is no macro=( And it's disgusting-just because it's not very pleasant to see such guests in the house...

That is, in principle, you can not worry, they themselves will "leave"? And they are not dangerous to humans? It's just not clear yet where they came from, if it's winter in the yard?

Thanks for the reply.
There is little information available on the Internet, so you may have some questions:
After yesterday's visual inspection of the attic floor (completely made of wood) and the attic room (you can walk around the attic room), I did not find any beetles or holes in the boards from larvae. All boards are dry and clean, with almost all boards, with the exception of four, removed the hump (personally pointed out the need to remove it to the builders). The house is new, completed in 2013, on the attic floor for four months found ten such beetles (it is inside the room, not in the attic).
Does such a large number of beetles indicate that the situation is dangerous? Is it possible to conclude from my personal inspection of the premises that the situation at the moment is not dangerous? Is it possible to continue breeding beetles if the humpback is removed, the tree is dry and clean?

Molorchos minor - small half-winged barbel. It develops in coniferous forests, the beetle overwinters in the cradle. In the heat, they started to come out of infected building materials, check the edged boards - if there are holes about 1-2 mm in diameter, then you are "lucky" and sold the infected materials...
In the logs of the house (sosbenno old) will not develop - all the beetles that are already in the boards will come out and die...
But other beetles can also develop in the same boards - if you use them, soak them thoroughly with antifungal impregnation (it also kills unwanted neighbors)...

There are no holes in the new boards , so they weren't brought with them?
Could they have brought it from the street closet with boards? (my husband made a crate out of them) - and if the ceiling has already been closed!! - then it is necessary to open it? -( or there are some other options. Thanks!

They will go to another world, flying around the apartment. You can use a sneaker to help. If they are road wasps, they are dangerous. They bite. If you grab it. If the rider is not. They don't bite. Road wasps "came" from the ground, where they spend the winter in predkukolkah. Changed for flowers? Rider-from a butterfly pupa. Perhaps someone has pupated in your apartment. And not just once, but several times. There are no other options.

Thanks! Well, apparently, it's still a wasp... So we will change the land in flowers, and then again the other day I met another individual on the windowsill!
And since the baby is expected to appear in the house soon, I would not like to be bitten again.
Can't it be a flying ant? My husband said that in the basement in the garage, too, never met and fought with this animal!

We stayed with relatives in Irkutsk. They brought a whole suitcase of such "beauty". I'm very worried, they were poisoning bedbugs not so long ago.
I looked on the Internet, they don't seem to look like bedbugs. These beetles are long, brown, the body seems to be divided into 2 halves, on the back of the back in the middle of the strip (either as for the wings, or just a smooth groove - they are very small impossible to see). The width is less than 1 mm and the length is approximately 4 mm. Our suitcase was standing on the floor, there were a lot of things in it, things were not moved either on the floor or on the bed, they somehow got there, maybe 50 pieces are enough (I hope). There were also a lot of potted flowers next to the suitcase. We have no bites, no redness, nothing.
I immediately packed all my things in bags, I'll spray dichlorvos inside, I'm getting ready to order an exterminator, I'm afraid that some kind of hit has escaped and is already preparing a plan to seize our apartment.
Maybe someone knows what kind of insects they are?
