HARRIS Diatomaceous Earth Food Grade, 4lb with Powder Duster Included in The Bag

Works well on a number of pests and highly recommend the duster to optimize application.

Great product..recommend!

Diatomaceous earth really helps to reduce the number of bugs in my space, and the duster included with this bag is really helpful for spreading it around indoors without creating a ton of visually obvious powder areas. You can puff it onto white walls and ceilings, and it’s basically not noticeable. I’d been putting diatomaceous earth on carpets and other places around baseboards and under furniture, too, which could look a little poor in some areas, but the duster included here helps me to diffuse more discreetly, and I even put a very thin layer over most of the open carpet area in my room that’s not really visible. Diatomaceous earth isn’t a 100% fail-proof solution all by itself, particularly for sugar ants (I recommend Terro and always keeping all foods well-sealed) and gnats/fruit flies (red wine vinegar and soap, fly paper, keeping the area clean), but it does seem to be one of the very best tools in my arsenal against insects. In combination, diatomaceous earth, sealing door and window gaps, Terro traps, a fly paper trap, and a vinegar, sugar, water, and soap trap when necessary seem to take care of 90-95% of bugs in my otherwise fairly vulnerable faux-studio bedroom space, and I reckon that diatomaceous earth does about 50% of the work. It seems to be particularly effective against spiders, thank god. Fortunately, I haven’t had much of an issue with houseflies, but I would guess that it would be somewhat effective for them, too, if you’re willing to diffuse it onto walls and window sills. Unless, I accidentally drop a large amount on the carpet or something, I don’t really vacuum this up or anything; I just apply every 6-12 months over as many surfaces as I feel I reasonably can, and I’m willing to accept a slight white cast or occasional white spots on surfaces and the risk of some minor skin irritation (not that I’ve really noticed any, apart from applying the product by hand) over having a lot of bugs in my space. I didn’t really use a mask or anything the first couple times I applied this stuff everywhere, which is probably really stupid of me as it’s not great for your lungs, so please take caution in that regard. My hope is that once it’s out of the air/settled, it’s not much of a lung health risk even if applied over a huge number of surfaces in a space, but it is a potential risk to be aware of.

We were experiencing a massive flea infestation and our home is tiled throughout. We tried flea collars and spray but all the spray did was make us cough. We decided to add DE in a flea killing triad of DE, traps and better collars and within 2 weeks the fleas were gone. The great thing about DE is it works against other pests as well and its not toxic.

i poured this throughout all my floorboards to help with a roach problem i had, it did help alot but did not eliminate them 100%, also extremely messy.

I love gardening and have grown some veggies in my back yard, I found some annoying bugs like pill bugs, ants and fungus gnats etc., I did a lot research and dont feel like to use something chemical which may harm the environment and human body health, so I decided to get this food grade Diatomaceous Earth with the duster and yellow traps and they works well, the powder is extremely fine just like girls loose powder. After few time of this, I did see some dead bugs, just spray a layer on the surface of potted plant to prevent fungus gnats , stir into the soil dirt and spray it to wherever has shadow that bugs loves to hide in, or spray on the plant leaves for any kind of caterpillar. California recently has roaches problem, Ive seen roaches shown like 2 years ago, this year they gets bigger and more, sometimes I take walk in hot summer midnight and I see some roaches on the sidewalks, lawns, they gather together especially around the fallen rotten fruits from trees just outside your house and I saw some in my back yard too, after blowing the dust away I sprayed the powder into the gap between house and concrete, it did a great job killing all the bugs, I saw dead drying roached the next few days and they less shown, DE can be used in both dry and wet, I like to use it dry, Ill consider non-food grade for just insect prevention and food grade one for edible plant, so far I highly recommend this and remember wearing face mask and goggles to protect yourself when using DE.

Soooo this stuff isn’t an overnight fix. BUT if you leave it down for *days* in places with bugs, and make sure the bugs are going through it, those bugs will die! :) I douse my house heavy when we go on vacations or trips. it’s not as effective on carpet/rooms with tons of furniture in my opinion, because bugs like fleas can hide a little. But this stuff WILL make any issue, less of an issue. Diatomaceous earth plus other preventative measures will help you and can’t harm anything! That said- don’t breathe it, wear an N95 mask when handling. Get a SHOP VAC with a filter to sweep it up! You’ll ruin regular sweepers. This stuff IS hard to clean up but in my opinion I always want a little on my floors to control any pests lol. After I shop vac, I take a wet clean mop and just get up majority of dust without stirring it up. All in all, thank God for diatomaceous earth! :) giving 4 out of 5 because it’s messyyyyyy and does take a while to work. But it WILL work when used right!

Silicates dust so put a mask on and safety glasses to protect your lungs and eyes. Better to have gloves as it dessicated skin. It is food grade as some people ingest it, but ask your doctor first and if you can take it, always drink a lot of water: it dehydrates badly. Anyway, put just a bit and spread it to obtain a thin layer. I use it only at the entrance of the garage where we have too many coach roaches.

Great product! Use it in the garden and make my own supplements with a capsule filler and a little bit of citric acid. The 4lb bag at this price gives me plenty for both. The applicator/blower is garbage. Upside down does just a little bit more than nothing. Outlets on the bottom will blow 90% of it out in the first two puffs and leave you with a stopped up mess, and after just a few tries the sides of the bellow are starting to wrinkle and bind. I ended up using an 8oz squeeze bottle and thats worked out perfect for the garden application. It can be very messy working with such a large bag so recommended that you use it outside with good air flow.

I put this around the perimeter of my home inside and out! I haven’t seen any crawling bugs in a LONG TIME! I am getting ready to move to a new location and I’ll definitely be using this product to get rid of AND prevent any unwanted critters from entering my home.
