Hi, I’m Rose with ZappBug and in this video we’re going to cover the use of Diatomaceous Earth to get rid of bed bugs. Diatomaceous earth is a chalky substance made of fossilized sea creatures called diatoms whose bodies were primarily silicon dioxide. It’s nontoxic and one of the safest ways we know of to kill bed bugs. When handling diatomaceous earth there’s a couple safety tips to keep in mind. As with any substances be cautious when using it around pets or small children. Diatomaceous earth is non-toxic when ingested, and it’s actually used for deworming pets, but even so I don’t recommend eating it. Prolonged contact with your skin will dry it out but it’s no big deal. If you experience that you can just use some moisturizer, and maybe talk to a doctor if you have any preexisting skin conditions you feel could get aggravated. The most important safety tip we have is that you don’t want to breathe any in. Always be cautious and use a dust mask when spreading it. Also, make sure you’re buying pet or food grade diatomaceous earth, not pool grade. This is a crucial difference: pool grade has much smaller particles and is a lot more hazardous if breathed in. I’ve also heard of insecticide diatomaceous earth that comes premixed with pesticides, but I haven’t seen any brands actually selling that, so keep an eye out and avoid any that’s labelled as such. As you can see, diatomaceous earth is a fine powder, similar to flour. Diatomaceous earth kills bed bugs by acting as a desiccant, which means that it dries out what it comes into contact with. You’ll be using diatomaceous earth as a barrier in areas you know bed bugs move around in. When they crawl through it diatomaceous earth disrupts their waxy shell and causes their eventual death by dehydration. This process is not instantaneous, so keep in mind that after using diatomaceous earth it takes approximately seven to seventeen days for bed bugs to die. The total length of time it will take varies depending on three things: what stage in the molting cycle the bed bug is in, how much of the DE they’re exposed to and for how long. So don’t panic – if you’ve spread diatomaceous earth and are still seeing bed bug activity for a couple days that doesn’t mean it’s not working. The diatomaceous earth we’re going to be using today is the Thomas Labs three pound jar of pet grade. We really like this version because it’s pretty cheap, comes with enough to get the job done but not too much, and also the easily re-sealable container. I bought this on Amazon and you can find a variety of different sizes and brands. We also have a link here and in the description if you’re interested. The brand itself doesn’t matter. As long as they’re pet or food grade they’re all going to be pretty comparable, and if you need more than three pounds there are larger sizes that are cheaper by weight. Bed bugs often travel through the walls of dwellings. We see this really often in apartment buildings — it’s one of the main ways that they spread from unit to unit. To prevent them from surviving in your walls you’re going to want to put some diatomaceous earth in your electrical outlets. First, just a safety reminder, make sure that you are wearing a mask before you spread any diatomaceous earth so you’re not breathing it in. Next, I recommend turning off the breaker for the room that you’re working in, just to be on the safe side. Whenever you’re working near electrical systems it’s always best to be extra cautious. Now that the breaker is off we can get started. All we need is our diatomaceous earth, a screwdriver to take the switch plate off, and a plastic spoon and duster to help us spread it. First, let’s take the plate off. Now you’ll just want to spread a thin layer of diatomaceous earth throughout the outlet gap. Depending on the size of the outlet you can use either a plastic spoon or a duster. For this outlet I’m using a duster. I bought this on Amazon and have a link in the description below if you’re interested. I’ve already filled this with diatomaceous earth so all I need to do is put my mask on, put the nozzle back in the outlet here, and press down. Before we put the face plate back on we’re going to want to put a little diatomaceous earth on it as well. We don’t need to go overboard here, but we want as much coverage as possible to make sure that we’re covering all our bases. You’re going to want to do this with all the outlets in your house just so that you know you’re covered. Another great way to use diatomaceous earth is to place it around the edges of your room. We want to do this for the same reason that we spread diatomaceous earth in our wall outlets: to prevent bed bugs from crawling through our walls and spreading even further. Here you can see the seam in between the wall and the floor where it’s possible for bed bugs to crawl and hide. Ideally we would want this seam to be calked closed, but that’s not always an option aesthetically or practically, especially if you’re in a rental unit. So our best bet is putting down enough diatomaceous earth that the bugs either don’t want to crawl through it, or if they do crawl through it they’ll be exposed to it and die. This is a really simple process and no real tools are required beyond some kind of spatula or any other flat edged object that you can use to push the diatomaceous earth into the crack. I’ve got my handy bucket of diatomaceous earth here and I’m just going to use a little plastic cup to scoop out some and place it down along the crack. You can use anything to scoop here, even spoons or measuring cups if that’s easy for you, the only thing that’s important is getting enough down. Now, I’m going to use this spatula to push the dust back into the crack. It’s that easy. If the crack is wide enough you can use a duster like we have here to push diatomaceous earth deep into the crevice. This one isn’t, but it’s the same principle. One of the best uses for diatomaceous earth is creating what we call a bed bug free zone in your bedroom. The principle behind this is using a much thicker layer of DE than we’ve used in our outlets and along the edges of our walls. We really want to get a nice, thick line here because we want to try and prevent bed bugs from approaching our bed while we sleep. We’re their primary source of food, so they’re naturally drawn to the bed above all other locations. But if the line is thick enough they won’t crawl through it at all. So we’re going to create a diatomaceous earth perimeter around our bed to establish a bed bug free zone and get a full night’s sleep. Now, you may still get a couple bites if there are bugs already inside the perimeter when you place it down, or if a couple bugs violate the perimeter anyway. But this will definitely severely reduce or eliminate the number of bites you’re getting. Also, keep in mind that bed bug bites can take a couple days to show up, so seeing bites after you create this perimeter doesn’t mean it isn’t working. All we need to do this is, as always, our dust mask, and any kind of scoop for the diatomaceous earth. A couple quick words about the dust mask before we spread this down. It may seem counterintuitive to you that we’re wearing a mask to spread it, but then you’ll be sleeping right by it after it’s down. The reason for this is because diatomaceous earth is nontoxic when it’s not being breathed in, and as long as there’s nothing that will disturb this dust you’re going to be totally fine. I wouldn’t recommend putting it in front of a heating vent or air conditioner or something else that’s going to disturb it. Now I’m going to create my barrier. As you can see I’m doing a much thicker amount than I did in the outlets or along the edges of the walls because I’m not trying to kill them as much as prevent them from coming near me. But that’s all you need to do. Now we’re done and you’ve successfully created a bed bug free zone around your bed. Remember that this step alone isn’t enough to kill bed bugs; you’ll want to follow the rest of our 8-step guide or use one of the ZappBug products to heat treat your belongings. Once you’ve finished treating your house you can vacuum up the barrier you’ve created; for more detailed instructions on that please see step one – creating a bed bug free zone. Next we’ll be moving on to step five: sealing cracks and crevices. Please click here or check out the link in the description.
