    Has anyone ever had problems with dry stuffy noses when you have DE down? Not like a cold where its plugged but just "noisy nose" and the nose is always crusted. My kids have been like this for months now. Even if I got the humidifier on full blast. The air just seems so dry even my lips always feel dry. My daughter also keeps breaking out in eczema, though that could be due to the hard water out here.

    I'm not an expert. Just sharing what I learned from my experience.

    It is very possible, DE contains silica, it sucks moist so it dries the ambience. DE is very light, so it can go airborne and end up in your nose... From what you say, i think that you over applied as for this to happen you have to use too much.

    My PCO over applied it. They coated my entire house with it. Imagine a bag of flour exploding everywhere. Took weeks to clean it up. Then I swept some under the base boards before I mopped up.

    If that was over 2 weeks ago, then you can clean the DE completely and you will feel better

    Dusts should not be applied like that.

    DE is produced by many different manufacturers for many different purposes beyond killing bed bugs. That means the source of the silica, the exact ingredients/amounts used, and the processing could all vary from manufacturer to manufacturer. That makes the efficacy of DE very variable but also raises questions about safety.

    In the US, potentially harmful crystalline silica is permitted in food-grade DE up to a certain percentage. But it's impossible to test every production of DE to ensure that it does not exceed the legal limitation. If applied following the label, health risk of food-grade is very minimal even if it does go a bit above limit. But, in situations like yours where it appears to have been spread in open spaces in high volume ("coated my entire house"), the risk is obviously higher.

    I don't want to be alarmist, but if I were you I would have you and your kids checked by a lung specialist especially since you're all having some symptoms which might be connected to the DE. It's much better to be cautious here. And I would consider demanding at least a refund which you should receive no problem since this appears to be a violation of the law.

    I believe you are located in the US. If they had dumped CimeXa all over (which is not advised either), you'd have had a lower health risk and a much better chance of resolving your bed bug issue. So why do PCOs in the US use DE for bed bug treatments? It might be due to ignorance, but also cost is a factor here. Most PCOs treat other pests besides bed bugs and they buy their pesticides in bulk. DE or products like Alpine (mostly DE) are less expensive than better dusts for bed bugs like CimeXa, Tempo, Drione.

    We weren't living in the house for weeks after the treatment. We carefully wiped and mopped all of it up. I just swept a little under all the baseboards to prevent any from trying to make a home there if a future i festation ever happens.

    I live in Canada, central Saskatchewan to precise. This guy was the only one willing to come to my home for the least amount of money. I'm not even sure what he sprayed as there was nothing on the invoice beisdes "fumigation". I saw him carrying a sprayer with greenish blue liquid inside. I have not been able to contact him for the paat few weeks. He may be on vacation.

    The followimg weeks after treatment I scrubbed the walls and floors down to wipe off any chemicals.

    We are currently renovating our floors and painting our walls. So we will clean up any DE left under the baseboards. We will then puff a bit of cimexa before sealing it up with red tape and putting new base boards on.

    You realize no fumigation was ever carried out since this is use of a gaseous component. He shouldn't be writing the word fumigation.

    I know that now. Unfortunately I did not know the difference when it was happening. Whatever he did killed the bugs thank god. But now it kind of scares me wondering what he really sprayed. Like I said I cannot get a hold of him right now to ask what he sprayed. Hopefully the town he came from answers my email asking about him.
