HARRIS Diatomaceous Earth Food Grade, Half Pound with Easy Application Puffer Tip

This stuff really works! HARRIS Diatomaceous Earth is super easy to use—so easy, in fact, that my 3-year-old climbed up on some boxes, opened it herself, and started sprinkling it on the ground like it was chalk art in a bottle (thankfully not on herself!). That just goes to show how user-friendly and mess-free it is.I applied it near our basement entrance, where we were seeing several ants a day creeping inside. After using it regularly—about once a week, the number dropped dramatically. From finding 10+ ants a day to just a couple a day in 2 weeks, and then eventually none at all after about a month. It made a huge difference.I also used it while in Hawaii, where the cockroach situation can be intense. The cockroach population definitely went down after use in the condo, and one morning I found several large dead cockroaches suddenly in a pot of water—something that had been sitting out for weeks with no activity before. Clearly, they were drying out and desperately searching for moisture.Pros:1) Easy to apply and non-toxic2) Very effective against ants and cockroaches3) Can be used both indoors and outdoors - be careful if indoorsCons:1) Requires reapplication for best results if it rains or gets windy2) Careful when applying if windy - DANGEROUS to inhale or get in eyes, otherwise non-toxicOverall, it’s an affordable, effective, and safe pest control option that I’ll continue to keep on hand. Highly recommend.

This works on plants, keeps critters away (rodents) and is also healthful to ingest (food grade only). It is helpful for hair, skin & nails, ingestion issues and more. There are many credible sites discussing human health benefits. ( it was hard to believe until I read them).

Had an issue with cockroaches when a previous roommate did not properly store their pets' food away and basically left the bags of food open in the garage. Unfortunately, when we started to see cockroaches near the garage it was already too late. The house was infested, bombing it was a temporary fix, but the cockroaches always came back after a few months. Preparing the house for fumigation was time-consuming due to the number of people and pets living here, and hiring a professional exterminator is too expensive for us.We researched more natural ways to keep the infestation at bay and found diatomaceous earth. It's food-grade, so if this was accidentally ingested it would be ok. You do have to be very careful though, because this powder is so fine and if we breathe it in, it is very harmful to our lungs and respiratory tract. We masked up and dusted the powder very lightly on areas where we knew the cockroaches appeared and where not a lot of people or pets would access often or for long. We sprayed a light mist of water to keep the powder from flying up into the air just in case. It took some time for the powder to show its effectiveness as we still were seeing cockroaches, but by the end of the month, we all suddenly thought that there weren't a lot of cockroach sightings as in previous months. Additionally, it did help with the large ant hills near our front door.We originally bought this as it was small and affordable to try, definitely a fraction of the cost compared to fumigating or calling a professional. If it didn't work we would at least be able to use this in our garden and say it was worth a try. Since it works, we will be buying more diatomaceous earth.Edit:It has been over half a year since we got this. Realistically, I will say this did not eliminate all cockroaches, unfortunately. However, it has been effective for our infestation with some patience and time. We were using this product almost daily for almost 3 months until it got to the point where we were only seeing a sighting of a cockroach once a month. After that, we would put more focus on the area where the cockroach was seen and use this product there.I hated to live in the house due to how disgusted I was with it, but now it is very livable. For those in dire situations with no possibility for a more permanent solution, this is still a highly effective temporary solution.

Good stuff and works well unless it gets wet

Safe, environmentally responsible, effective pest management! Sprinkle around doors and windows, wait three days, bugs are gone.

I purchased this product after being told that it could help prevent ants from entering my home. I was skeptical, but it has worked like a charm. Very few ants in the house after creating a barrier.

I bought this product because of the "application tip", the size (not a large bag), and the container. I had used DE before and knew it worked. Before I bought 1 kilogram (2.2 lb) food grade in a sealed bag. It was a large bag that lasted a very long time. I knew it was safe so it won't hurt my pets.However, I do not know what to think about this product.What I did not like is that the product comes NOT sealed. So, it can easily be tampered with or mixed with other things. Before using it, I contacted Harris to see if they sent the products sealed or not. They send them unsealed, which is crazy to me.So I used it. It took a while to eliminate the ants that had appeared in the kitchen. Because it is "food grade", I felt it was safe for my pets and myself. But since I applied it in some areas of the kitchen, my cats started vomiting and one of them got really sick with vomits. The vet thought he had been poisoned but did not have enough poison; thus he got really sick but got well. The only thing that I had used new was this stuff. Not to say that I got rid of any little spot of this product and the rest went to the pharmacy container to return dangerous medications.Next time, I will buy a sealed DE food-grade bag and take my time to put it nicely in key spots. Oh, the application tip is a joke so you would be better off buying a bag.
