HARRIS TUHIMO Diatomaceous Earth Food Grade, 2lb

This dust is very messy, but very effective! I have used it to stop garden pests, to keep vermin out of my cabins & sheds, to stop ant trails into my house, to dust cats & dogs to get rid of flea infestations, to dust environments to kill fleas, and even fed it to pets to kill intestinal parasites. It is wonderful stuff. It works by mechanically scraping the waxy coating off an insect. This makes it lose water rapidly, dehydrate and die. It's a mechanical effect so they cannot really ever develop a resistance to it, and the effect happens slowly, so the insects never learn to associate the powder with illness. They just crawl through it, and to them, it is like crawling through broken glass. If they scrape or clean it off themselves, they're only speeding up the effect. The only problem is handling it - it's messy, although it doesn't stain, is chemically inert, and is easy to wipe or wash off with water. The bag is sealed, but the internal zip-lock seal is not, so when you tear that opening, do it slowly or use scissors, and have the bag inside another, plastic bag to contain any puffs of powder that come out. I recommend a powder duster tool to use this, but you can also cut the corner of a zip-lock bag and use that to dispense the powder. A small spoon will also do the trick. Dust around the door jambs, behind fridges & stoves, and wherever else moisture or bugs are likely to congregate. The powder contains silica (diatom shells are made of it), but as I recall, this is not a reactive form of silica, so you cannot get silicosis from it. It is not dangerous like other silicates are, but it can cause mild respiratory irritation if you use it a lot. You can wear a mask when you dust it, or just do what I do and pull your shirt collar up to cover your nose. For normal use around the house, you probably won't need to do any of this. I just mention it for those who will be using this heavily and often. EDIT: I'd like to add some information. I did a LOT of research about whether food grade diatomaceous earth is dangerous. It is not! It is USDA approved as generally safe for people and pets. It's the amorphous and crystalline silica that's dangerous, and those are found in insecticide DE and filter medium DE, not food grade DE. Food grade DE is purified. You can use it with no worries. I cannot add links to a review, but you can try searching "food grade diatomaceous earth safe" or similar, to find a number of science papers.

I bought this food-grade diatomaceous earth for my raised beds, and it works wonderfully. It has been highly effective at protecting my tomates, cucumbers, and peppers from crawling pests. I love that’s it’s OMRI listed and safe to use on edible plants. Excellent quality and easy to apply around the garden.

This stuff works great, but it's messy and covers everything. Distributing it evenly is a task, but it kills the fleas. You'll have to repeat the process to break the fleanlife cycle, so plan on making a mess more than once. Do your research, watch videos, read up on it and be vigilant.

Kills the bugs naturally

Woke up one morning with bite marks on upper legs, a few more bites 2 days later. Did research & immediately sprayed clove spray, let it dry some, then spread baking soda to the mattress later, moved to the couch to sleep, sprayed orange & Citronella spray on couch, a few days later I spread the powder around the house perimeters, have not been bitten again after a week. I think the combination of things work great, but I think the Earth powder topped it off
