Haven't yet tried

We live in the city and sadly, so do roaches. Our apartment building got infested and the landlord was too cheap to call an exterminator. I heard the DE is supposed to help with killing and preventing roaches, so I bought this as a safer alternative to poison. The day it came in, the landlord had an exterminator come it. We still have a few roaches, so I'm going to get this out ASAP.

Didn't affect the fleas at all sadly

I put it in some dust baths in hopes of treating small animals without dangerous chemicals but it has failed. Dropped directly on fleas and they just climb out and jump away. Disappointing but I guess it works for some added nutrients to their food. That's about it.

Miracle in a bag!

I live in south fl and the ants here are unreal! My apartment has the worst Ant problem top that off with cat food and I couldnt win. I have tried it all! The terro drops did absolutely nothing and that typically is my cure for ants in the past. I even did a water moat and I swear these ants can swim. I got this and sprinkled a bit on trays with the food bowls and a little around the base board near the food and not one ant!! Its been almost two weeks!! I could cry happy tears!!! Its safe for my babies and solved my issues! I highly recommend!

I'm not one to review products

I usually don't leave reviews of products that I purchased. I ordered this as I was having a problem with roaches around my parrot cage. Just put some around his cage yesterday afternoon. I didn't expect results so quickly. Like I do ever night pick up news papers from around his cage to catch his poop. Tonight 1 lone roach usually over a couple of dozens run from me. Safe for all pet's and humans I'll be keeping this on hand as I live in an apartment building. Couldn't be any happier with the results. Believe me I've tried everything

Food Grade Diatomaceous Earth

I buy food grade only to sprinkle around the outside pet food bowls. Keeps bugs out of their food

This is the best and safest to kill flea cycles!

I have tried this multiple times and is the best and safest to kill flea cycles and other insects. I will not use anything else anymore! I have recommended to friends many times!

Must have

Great, if you have feral cats or scaredy-cats that you have problems treating for fleas this is the solution. You just mix it in their food. Also, it is safer than Bravecto & those types of digestible flea treatments.

Great for the litterbox!

I got this to try for worms in one of my cats and read that it can be used in litter boxes. Haven't tried it for worms yet but it IS what I've been looking for in the litterboxes! I have 3 neutered male cats and no litter makes scoopable clumps of their urine. Baking soda helps but nothing made unbreakable clumps. Since using diatomaceous earth I don't have to sift forever when scooping the boxes. Clumps are firm and don't break into 1,000 pieces.

It sure is Diatomaceous Earth

Beware on using this anywhere near where you inhabit daily. It works so well because its so fine and can dry out the tinest of insects but by golly does it get absolutely everyWhere

Do NOT put this on painted cement floors!!!!

So when we moved into new house there was a feral cat situation in the crawl space and had an out break of fleas. I read about this & thought I'd try this to see if it would help in case had same problem the following Spring/Summer so I made the HUGE mistake & put this all over the basement floor & in crawl space. OMG it's like this stuff bonded w/ the paint on the cement floor. I swept, vacuumed, used cleaners & scrubbed & scrubbed & STILL there is a white film/ speckles all over the floor. Floor has to be repainted. I'm still furious that this ruined floors. Oh & this stuff did nada what so ever to help w/ fleas & had another outbreak.
