On the glassed-in balcony, hay eaters and a couple of false scorpions were bred in a box of old books. I vacuumed them all, put the books in the freezer, and threw the box away. On the back wall of the box, I found a spot covered with what looked like dark brown dots. Is this masonry? excrement?

The balcony and all the objects on it were thoroughly vacuumed, washed and calmed down, and three days later I found hay eaters on the balcony step from the side of the room! I smeared it with cockroach chalk, applied a layer of insect repellent gel, but I don't know how many of them have already leaked to my house or how many more animals are left on the balcony. I definitely have them at home, because I've been regularly shaking up my bookshelves for a week now and I find a few of them every time.
I called about a dozen pest control offices, someone suggests outright profanity - spray the floors and skirting boards, someone suggests hot fog as a radical measure.

I scoured the Internet and was completely upset - they write that it is almost impossible to withdraw them.
Good people, help me with tips and info, I'm desperate. There are a lot of books at home, some old and some expensive. How to protect books and remove book lice in the apartment?
What methods and poisons are effective? Is it worth trying disinsection or is it a deliberate divorce from which there will be no effect?
Where do the parasites lay their eggs - in the spines of books or something? I read that they lay eggs in the fall, which means that they are just about to lay their eggs in our house.

The apartment is dry and cool, the windows are always open, so they (theoretically) should not like it. However, there are 3 large bookshelves that I can't get rid of.
Pozh-sta, save-help. Any tips and info are welcome.

Thanks for the link, I read that topic several times, but after it left the impression that getting rid of these creatures in the apartment is not realistic.
I've called a dozen and a half dez for today.offices, but the feeling that most offer garbage-irrigation of floors and skirting boards by the type of cockroach baiting. But these things move on walls, don't they, not just on floors?
You are like a pro, if you work at a dez. station and you have poisoned reptiles yourself, can you tell me how to poison them in a residential apartment, not a warehouse? What poisons? which method? How do I process books that have already been infiltrated by the critters? I already have a neurosis on the basis of these beetles, I'm afraid that they will multiply at home and will run in herds...

So it's not clear if Grandpa was poisoned or you? I don't even know what could be done in order to be guaranteed to be poisoned by it - the body itself will tell you what to dump when it feels its unique aroma ))
In fact, the devil is not so terrible as it is painted)). If SO2 were so toxic, it would not be used as a preservative or as a fumigant for processing greenhouses with vegetables and fruits. It does not change the composition of the blood, as, for example, cyano - or hydrogen sulfide, also does not cure cancer, like some organic matter, and does not accumulate in the body, like heavy Iu compounds. All that it can cause is local irritation of the mucous membranes, due to its acidic environment (with water it forms sulfurous acid H2SO3), but of course in high concentrations - suffocation, so any, even non-toxic gas will cause it if you displace oxygen (air). No one will, I hope they purposefully breathe or drink the solution )) I immediately wrote that you can get poisoned if you don't use your mind.
But all the filth, including mold, kills at once. Just then you need to ventilate well and that's it. By the way, in the old entomology manuals it is recommended as one of the methods of soaking in stains.
P. S. Any soda is extinguished-Na2CO3, NaHCO3, and even better caustic-NaOH )))

I'm ready to fumigate the apartment for many days with anything, just to get the creatures out and not let them multiply. Unfortunately, I don't know much about chemistry myself, and I don't understand how this is technically feasible.

If you can, please tell me the steps:
1. Balconies - they are glazed, but the frames are old wooden (the floors get wet and there is mold), so there is no tightness, but there is plenty of food for the creatures. How can they be processed and in what way? (irrigation, cold steam, hot steam, or just spray the walls and floor with what?)

2. Apartment - a lot of books, 10 indoor flowers.
How to process the apartment and in what way so that there is an effect? How to process books, because cold steam is probably impossible and not effective?

3. How and how often do the creatures reproduce? Where do they make masonry-in books or where?

I keep calling dez. most of them don't even understand what kind of insects I'm talking about and suggest that I poison them like cockroaches.

Dear AGG suggested Ziper and Cyfox, I'm trying to find out who works with them.
But I didn't understand, are they both for hot fog or for cold fog too? In general, in the case of a residential apartment with a bunch of books, will the cold fog work?

Well, in this situation, even now I don't know if you should get involved with it... I thought you knew some of the basics, after all. And then what good is really poisoned, and I will be to blame ))
In what form? This is an acidic gas - sulfur dioxide, anhydride of sulfurous acid, as I have already written. With water, it forms a weak sulfuric acid (not to be confused with sulfuric acid!). Non-flammable and non-explosive. There are several ways to get
it: 1.Burning elemental sulfur (just not from matches, there is little sulfur in them), and which is sold in a pharmacy, yellow, sometimes comes across even in coal, technical sulfur.
S+O2=SO2
First, the sulfur melts, and then ignites and burns quietly to form dioxide. You can burn it on any metal surface.
2. Or you can act with a stronger acid on any salt of sulfurous or thioseric acid-bisulfite, sulfite or thiosulfate, for example, sodium.
Na2SO3+2HCl= 2NaCl+H2O+SO2
To do this, add hydrochloric or even better, dilute sulfuric acid to the powder of this salt. Intensive release of carbon dioxide will begin. The main thing is to get out of there in time so that you don't get enough of it yourself )) it is best to use chemical utensils for this purpose, such as a large flask, since the reaction is exothermic. Reagents are mixed at the bottom, it is necessary that there is a reserve of space in the vessel so that it does not pop over the edge.
Why did I recommend it - it is also used in agriculture for this purpose, even special smoke bombs are sold, they fumigate edible plants in greenhouses, that is, it is certainly poisonous, but only if they breathe purposefully. As it is, it just fades out and that's it. Neutralized with a solution of soda if anything.
But if this is how you feel about chemistry, then maybe you shouldn't mess with it? It's up to you.

Wow, chemical knowledge ))

As for sulfur and poisoning, I remembered two cases-as it was still at school, we decided to set fire to sulfur, toli mixed with aluminum toli on an aluminum plate.. And neither where nibut and in the room, yo.. It burned a little bit, on the tip of the knife, and there was a stench))
Another case about sulfur-as I decided to throw off the black film with such a type of Ag999.9 catalytic plate with a developed surface, there are hundreds of square meters. cm, somewhere I read that to clean any costume jewelry, you need to add salt, soda, an aluminum object to boiling water, throw a ring there and it will lighten the image.. Well, I did so with this plate - so everything sizzled, such a stench went sharp, that it was already bad...then I read more and there is a possibility of hydrogen sulfide release )
So let the hay eaters live better!) Suddenly sulfur on aluminum will burn? )))

Actually, the" problem " isachalnaya strange, this is of course someone like, but .. hay eaters.. they are absolutely harmless, to poison them with something is to harm yourself..

01.09.2016 13:19, коты

What kind of knowledge is there, I beg you )) school course of inorganic chemistry... well, in general, yes, there was a hobby at the amateur level in my youth.
When sulfur reacts with aluminum, aluminum sulfide is formed - a salt of hydrosulfuric acid, and it, in turn, releases hydrogen sulfide in the presence of moisture, while hydrolyzing, and completely, so that water-insoluble compounds, gas and sediment are formed:
Al2S3+6H2O= 2Al (OH) 3+3H2S
This hydrogen sulfide will be more poisonous than sulfur oxide - it binds the iron of blood hemoglobin to sulfide, the blood literally turns black, besides nerve poison, etc.
And silver is best cleaned with a solution of ammonia (ammonia), it dissolves the oxide, forming a complex, but it does not react with the Me itself.

They also feed on mold fungi, that is, you know, here you still need to lower the humidity somehow - increasing the temperature, blowing air (in kstti book storages - necessarily).. You will get stoned with sulfur, even if it helps that after a while the hay eaters will start up again.

I understand all this. They divorced initially on the balcony, there are old wooden panels with mold, from the rain get wet. When I spotted the critters and cleaned out the balcony, threw out the box where they obviously had a nest, and shook out the old wooden table that hadn't been climbed in a couple of years, the critters started running to our apartment.
More precisely, I do not know, maybe they ran over before, just did not notice them. And now I purposefully wash everything at home-I vacuum and check the books-nightstands for their presence. And I find the creatures. Today, on the bottom shelf of the cabinet, where we store documents and photos, I found 4-5 pieces in a new package of paper!

The apartment is not very humid, the windows are always open, the apartment has fresh drafts.
During the heating season, the air becomes very dry, previously a humidifier was used. We probably won't do it now. I'd just like to keep them from spreading all over the house for a start.
How do these things move? on walls, ceilings, skirting boards?
Where do they lay their eggs?

Sorry, but what does gypsum, sulfur and combustion have to do with it? Gypsum does not belong to the category of combustible substances, because it does not burn. Generally. When strongly heated, it loses all water, since it is a calcium sulfate crystallohydrate-CaSO4×2H2O and will no longer solidify, even with the addition of water. But it will not burn and it is generally a very inert substance in chemical terms. The formula contains sulfur, yes, but this formula can no longer be destroyed, because the salt of alkaline earth Me, and even sulfuric acid, and as you know, sulfuric acid displaces everything, even stronger acids from their salts, but sulfuric acid can no longer be displaced by anything, because there is no such acid to it competed with her in terms of density and strength at the same time. White smoke was most likely caused by the burning of aluminum, it burns perfectly in the air with the formation of white oxide Al2O3.

You're right, I don't know about this issue.
But let's try to figure it out. You write that this is a fuel-oxidizing mixture and an oxidizer-gypsum, i.e. CaSO4, in fact. And do you also cite nitrate as an analog? What are oxidizing agents in the combustion of substances? These are elements whose strongest element is fluorine (which decomposes even water at n. o.), followed by oxygen, chlorine, bromine, and iodine. Nitrates are only carriers of these elements, in this case elementary oxygen, as well as permanganates, chlorates-perchlorates, releasing it during ignition, impact, etc. But what other than intergranular water can gypsum release? Oxygen? Sulfur? How can it oxidize aluminum? With very strong heating, it decomposes into sulfur anhydride-SO3, that's the oxidizer, perhaps it is the culprit of the celebration )) Well, then it's clear, so in the process of writing I still got to the bottom of the a priori truth ))) thank you for enlightening me, I didn't know. Only a very strong heat is needed to initiate the reaction. What reaction products are obtained? Depending on what substances will be in excess, if you mix stoichiometrically by reaction, then most likely aluminum sulfate, calcium oxide is formed, like this:
3CaSO4+2Al= Al2(SO4)3+3CaO, although I may be wrong.

They move around wherever they want, and lay their eggs where they crawl. So if they wanted to then have long been crawling around the house, I say-try to use the rapator.. Well, or call the team uh, they will not only etch out the hay eaters, but everything that is poisoned )

Can they also do masonry work in books, or only on hard surfaces?

I do not know how long ago they began to leak to us-all summer from the moment I noticed them on the balcony in a box, or in the last week, as I washed the balconies...

I smeared the shelves of bookcases with cockroach chalk, window and balcony openings leading to the apartment, Raptor-gel from cockroaches and ants, "hot spots" on the balconies sprinkled with Insect Repellent Raid.

Today I talked with another "bragida uh". They assured me that they have a lot of experience in etching hay eaters. Use Xulat, something on c.., myxomin (but this is an antiseptic, what is it for?) and a bunch of other stuff. They offer complex processing (hol+gor+barrier), but books and all papers are not processed, they need to be covered with a film. How, then, can we punish those who have already hidden in the books???

My husband is against any treatments, he is afraid that we ourselves will spend money for the company. He thinks that there are no problems yet, "suddenly they will not take root," and I am panicked that they will breed all over the apartment.

As for the oxidizer, my terminology is rather not chemical, but pyrotechnic. Oxygen or sulfur? Yes, probably both. I read about such mixtures that sulfides are still formed in the products of combustion, although there was still elementary sulfur in the composition, maybe from it. But I excluded sulfur, because it is difficult to get it from us, except in scanty bags in the vetaptek. The proportions, if not confused, are as follows: alabaster-12, aluminum-10, KNO3-3. Nitrate provides greater ease of arson, but I think it will also burn without it, although you need to choose a different proportion and make the fuse hotter. Mixed with vodka (greetings to Pan Stepovoi). Just on the water is impossible-aluminum powder is not wetted with it. The resulting "porridge" is slightly pressed into cardboard sleeves from toilet paper, and dried for a couple of days, it turns out very technologically and not dusty (compared to compositions with silverware without gypsum). It is set on fire relatively easily with an ordinary sparkler in the amount of this piece. It burns like this (somewhere between 60-80 g):

Here you can see white smoke rising from the top, and red-hot slag pouring down, the composition of which just interests me, as well as a purple halo from potassium ions (with sodium nitrate it turns out a bright yellow color, with the addition of chalk - a light red hue, but for some reason calcium from gypsum does not appear).

But I think that next time (after the war, because now you can go "to the basement" for pyrotechnic experiments in the yard, and this is correct), nitrate should be excluded altogether, and it will probably burn more slowly, because it is very violent and fast with it. And the cost reduction is considerable. In general, mixtures based on calcium and barium sulfates (lighting and incendiary) were invented by the Germans at the end of the Second World War, when they began to feel interruptions in nitrates and chlorates.

Thank you, very curious, it never occurred to me that gypsum can generally be used as an oxidizer in pyrotechnic compositions )) at first I thought that this mixture is similar to termite, but no, in termites-oxides are times, and secondly, most importantly-in termites, more active Me reduces less active, and it is oxidized at the same time. Here, calcium is much more to the left in the series of Iu stresses than aluminum.Now I thought about it... if all these substances (take without nitrates, sulfur, etc.) are selected in stoichiometric quantities according to the reaction, then the final products will most likely still be aluminum sulfate and calcium oxide, since gypsum does not directly emit either O2 or S, but sulfur anhydride-SO3. But! If the quantitative ratios of the components change, a different reaction course is also possible, since SO3 can also undergo thermal decomposition into O2 and SO2, and excess aluminum can reduce SO2 to S. So the formation of sulfides is also possible. Plus, at such high temperatures, the formation of calcium aluminate can occur at all, since calcium is replaced by alkaline-earth Me, and aluminum by amphoteric Me.
In general, calcium ions turn the flame brick-like.
And why only after the war? I thought that on the contrary, when there is a war, then there is more lawlessness
about weapons - war after all. And if that, then there is dvzhe justification-arm ourselves, and what to do, suddenly the enemy will attack my house ))
Secondly, this is pyrotechnics, not high-explosive devices. What's the use of it? Light and noise effects. If this were the case, then long ago all the youngsters would have been transferred for explosive packages with magnesium and potassium permanganate...

Gentlemen, the creatures seem to have spread all over the apartment. They don't catch my eye (yet), but today when disassembling kitchen cabinets, I found 3 pieces in an old box with a mixer! I threw out the box, washed the shelves.
Kitchen cabinets are made of ordinary chipboard, there are dark spots on the back walls - I can't figure out whether it's just greasy drops of something, or dirt, or mold (but where would the mold come from? our apartment is dry, the ventilation is good, it doesn't seem like it should be). What you can use to clean kitchen cabinets to kill mold (if any). but so that you don't get poisoned yourself? Someone wrote about chlorine, but I am familiar with it only in the form of Domestos and in chemistry I am not strong at all.
You can explain to me in a very accessible language - what to use? While wiped with a formaldehyde solution, but I don't know if it will help or not. But I've had enough of it myself, and now my throat feels really bad...
My husband is still against treating the apartment with smoke, he is afraid that we ourselves will be poisoned. And I have a growing panic, I'm afraid of insects.

And spray dichlorvos from crawlers in the morning with a couple of cans on the room with the windows closed and immediately leave it for a day, and come and ventilate in the evening? And not so much like dead.

Dichlorvos really stinks, I have asthma, I will die before the creatures. There are less smelly tools, such as Raid / Kombat, I can try them. Where exactly to spray? on the floor? on the walls? in closets with things? I don't understand where things can come in contact with poison. They do not catch your eye, you need to look for them purposefully. In the kitchen, I went through all the cupboards, checked all the crusty cans, and found no more critters. Surprisingly, in the cabinet with cereals-pasta-cookies was not a single reptile, and found in the farthest cabinet with kitchen inedible gadgets. Where is the logic?
Well, the problem is, we only have doors in the rooms. In the hall-corridor-hallway-kitchen there are no doors, and this is a significant part of the apartment, that is, it will not be possible to close it. Unless you spray the whole apartment at once. I'm already thinking of buying a tub of Xulata and a garden sprayer and spraying everything myself. Only I'm afraid that it will come to a divorce from my husband, he yells that I'm paranoid and that he personally does not see any reptiles and they do not interfere with him, and is angry at the traces of chalk in the bookcases and the smell of gel from cockroaches around the balcony openings. It's scary to imagine what will happen to him from the smell of poison.

Raids and combat units are no longer operating in the same way as they were twenty-five years ago.

Spray where possible, but mostly just in the middle of the room, so that the vapors fill it completely in the absence of fresh air from the windows, then you don't need to dust in every crack, the vapors will get there by themselves. But don't leave the shelves closed.

Of course, the whole apartment at once, otherwise what's the use.

Solve your asthma and husband's problems at your own discretion. You can ask someone, and not to poison yourself, you can spend money on personal protective equipment, if it is so important for you to lime the fauna.

I don't recommend changing your apartment. In any apartment where not since yesterday they live without major repairs, if you search well, you can find so much inconspicuous fauna that only you know grass. And someone has enough noticeable information.

Thank you for your tips. And then what should I use, ordinary Dichlorvos? That is, you just need to block up the windows and spray into the air, I understand correctly, opening all the shelves and lockers?
We have a gas mask, I think it will be enough.
Today I dismantled another forgotten place in the kitchen - the kitchen sofa. I found 2 live creatures and 3-4 pieces of dry corpses. Have they been living with us for a long time???

If I didn't completely kill the reptiles, at least I wouldn't let them breed. Already in the shudder throws as I see them when searching. Changing the apartment is not an option, we live in our own and we are satisfied with it. Yes, and things are still difficult to process carefully.

I called a couple more dez. companies. Prices for repeated calls are growing right before our eyes... In one, I was told that they process the apartment and balconies only with the permission of their neighbors. Awesome.
