Leatherworms: reproduction and control

Good afternoon!

The topic has been repeatedly discussed here, but I would like to touch on a slightly different aspect of it.

Background:
we lived in a rented apartment, lived for a year everything was without problems.
As I was mopping the floor, I saw a bug, another small gray-black-brown one - I didn't care if there were any beetles flying in the window - I always catch them or throw them back out or down the toilet

Then they didn't live at home for some time, because of the circumstances, they rarely stopped by. When they returned, they began to find the larvae of the kozheed (what it is, I learned after a long search on the Internet).
It turned out that they divorced in the room, near the through ( through all floors ) pipes and in the kitchen near the same pipes.
In the room there were three sofa cushions near the pipes and an Ikea box with small things (books, charging equipment, etc.), and in the kitchen a refrigerator.

I'll say right away that I'm still clean, I'm not very good with this topic, I'm paranoid about cleanliness - "I rub and mine and vacuum, mine, vacuum and rub", and everything in a row.

I was upset in general because of this, I washed everything, cleaned the pillows, shook the box and everything was OK, I decided.
Then we began to move in with our parents, and even forgot about this topic, we moved this Ikea box, an ironing board, a table. We stayed with our parents there for about a month and came back with this stuff.
I began to do the cleaning, as always moved the pillows to propylisositat, and there are about six of these larvae.
I began to examine everything, found in the sofa, in the underwear drawer, at the junction of several more of the same, and there were small ones there.
I bought sprays from kozheeda, plates, steamer.
The work was colossal, vacuumed all the sofa and processed, untwisted it all, and the bottom was also vacuumed.
They shook up all the things in all the closets.
They tore off the skirting board where they found them, and there's a bunch of these skins from them, and they're crawling here and there.
They tore off all the baseboards, vacuumed them, and sprayed them with a leatherworm remedy and scratched them with an insect repellent pencil. Glued the skirting boards.
We decided to wait a couple of weeks.
Still, we'll see one here and there in the next couple of weeks.
In general, we moved out.
When moving, all things were shaken up, what furniture was rubbed.

The second part of the story. After we left, my mother also began to find these maggots in her home.
My parents have a new two-story house, so I found 3 pieces on the second floor, we just put our things on the second floor.
Then I found one maggot on the first one.
And so 4 months have already passed, and she finds them one by one.
Once I even caught a bug that looked like this leatherhead-like it was.
And my mother is already shaking from these maggots.

I also forgot to tell you that I gave my mother a pillow before we found out about these leatherheads, and the pillow was lying in my sofa right now. But I would still have noticed them on the pillow I think when I took it from there.

And a full out. Yesterday, at work, I saw a bug on the window, apparently it was a leatherworm.
And a day earlier, on the wall, at a height of about 1.5 m, I saw a light brown worm crawling, it was very small, about 1 mm long,but it looked like a larva.

Are they following me?!

In general, what we have. Within a few months, I developed a persistent neurosis from this infection. I vacuum every day, including furniture, wipe all surfaces and wash floors every day. And I do it after work, so I get very tired

My parents had all sorts of moth and skin-eating plates put up everywhere.

I would like to clarify how these infections can be implicitly bred? I can't figure out where my parents got them from. did the pillow and our box really crawl so much? And again, how implicitly can they divorce? is it possible to transfer the larva on clothes when it is very small or it will crawl into the bag there or somewhere else?! Otherwise, I have a constant feeling that I carry them on my things. You may say so, but I say it as it is.

And if we do not see beetles in the house, but only larvae - is there a chance that they will divorce? I understand that beetles exist in the open, so if there are no beetles, then there won't be any new larvae, right?

And by breeding, I understand that the larva would appear, should two beetles of different sexes meet? or they are something like that, on their own. I can't find anything about breeding on the Internet(

Thank you in advance! help my neurosis)

I would like to clarify how these infections can be implicitly bred?

Just like "explicitly" - easy, easy, natural. For example, you etched your apartment (and yourself at the same

time) with chemicals, but your neighbors didn't. A holy place is never empty - breeding beetles need a living space-voila. Do not forget that kozheeds fly perfectly, which greatly facilitates their "development of new territories". By the way, about the flight: try to inspect the indoor lighting devices (sconces, chandeliers, etc.) - behind the glass covering the lamps, dead beetles should be found in the shades, attracted by the light source (like many flying insects) and died there from high temperature.

I can't figure out where my parents got them from. did the pillow and our box really crawl so much?

Maybe even with a box. And with a pillow. And they could crawl (fly) from neighbors, from the street, etc. They could generally exist in small numbers in their parents ' apartment before and simply not catch the eye, until they massively multiplied when creating favorable conditions.
In general, many species of leatherworms living in our apartments (houses) do not need much to survive: a small amount of dust behind the baseboards, which always contains organic residues, is enough to feed the larvae. In nature, these beetles develop at the expense of such remnants in the nests of birds, mammals, social insects (bees, wasps, bumblebees), even spiders (remains of "half-eaten" (dead) insects, larval skins, etc.).

And if we do not see beetles in the house, but only larvae - is there a chance that they will divorce?

Of course! Not a chance, but a pattern: everything goes in a circle-egg-larva-pupa-imago (adult beetle)-egg again and ... everything will repeat again from the beginning. Like everything else on the planet.

I understand that beetles exist in the open, so if there are no beetles, then there won't be any new larvae, right?

So - and-so

. Of course, if there are no beetles, there is no place for larvae to come from. But just because you don't see beetles doesn't mean there aren't any. Larvae do not self-originate, they hatch from eggs laid by beetles. Just beetles lead a secretive lifestyle, which largely flows "in the corners", behind the same baseboards... Beetles come across when there are relatively many of them, during their mass hatching and summer. Once there are larvae, they will turn into beetles at the appropriate time in their life cycle.

And by breeding, I understand that the larva would appear, should two beetles of different sexes meet? or they are something like that, on their own.

In this matter, you almost figured out on your own

- there is no sexual reproduction in kozheaters.

Any rule is only a rule when there are exceptions to it.
I do not think that in this case we are talking specifically about Reesa vespulae: most likely, someone from the genus Anthrenus or (as one of the most common variants today) Attagenus smirnovi.

Dmitry, thank you for such a detailed answer!

I looked on the Internet, by the type of beetles that we saw, yes, it seems exactly this
Attagenus smirnovi

My mother told me yesterday that on the second floor, near the battery, 2 larvae crawled out from under the baseboard, and then I caught two more there. My parents have laminate flooring and plastic skirting boards.
My mother began vacuuming under the baseboard, and the beetle was "sucked" into the vacuum cleaner from there.

On Saturday, we agreed to remove the baseboards and vacuum everything behind them and miss Masha with a pencil.

What do you think is a good idea?

Despite the references in the literature, I myself have never "caught"

Attagenus smirnovi for "obvious sabotage", although in my apartment they periodically (though not so abundantly) appear. At the same time, I have a fairly large collection of insects at home, which seems to be attractive to leatherworkers (ugh, ugh, ugh!!!). However, as a preventive measure, scaring away fans of dry organic residues, I use anti-flea cat collars, cutting them and putting the pieces on the shelves in the cabinet with the collection (replacement according to the expiration date of the collar indicated on the package). And Attagenus smirnovi, according to my observations, is quite satisfied with eating dust accumulations behind baseboards.

This is normal

: plastic baseboards do not guarantee the absence of dust.

Try it: at least for a while, it may help. Only here is the idea with a frequency of once a quarter (and even in six months, a year) to remove the skirting boards in the entire dwelling and vacuum them personally would not inspire me: if the number of beetles is such that you see not swarms, but one or three periodically coming out into the light, I would accept: let them chew for themselves dust behind the baseboards.

I also encountered this problem. periodically I saw these beetles in the apartment (more often on the curtains and windowsill). And usually this happened in the spring - when the sun began to shine brightly. Apparently, these parasites flew out into the light. Asking friends - if anyone has such-many answered-it's from flower pots or flew out of the window. But after studying this topic on the Internet, I began to actively fight them. And now I'm struggling.
What I'm doing:
1. I periodically process the skirting boards with a toilet cleaner (a very thermonuclear thing), while opening the windows in the house. I do the same with wardrobes, sofas and other furniture where I find beetles or maggots. They live not only behind baseboards, but also in the sofa lining hide. I also want to buy a spray gun and dilute a concentrated solution with toilet washing liquid and treat the sofas (the part that comes into contact with the wall).
2. I bought boric acid at the pharmacy (in our city of Tomsk 1paketik 40 rubles) and fell asleep behind the baseboard.
3. I made an audit of the wardrobe and periodically throw out unnecessary things - you can not save anything and put it off if you have leather eaters in your apartment.
4. Do not help the moth remedies that I periodically put in the sofas

I DON'T KNOW HOW IT WILL END YET - which of us will survive
